ProtaStructure v9.0.445 delivers the most comprehensive structural analysis software improvement in 2026<\/strong> to date. Specifically, this release targets RC column design, seismic analysis, reinforcement detailing, and BIM modelling. Furthermore, every update addresses a real pain point that structural engineers face daily.<\/p>\n

In this article, we walk you through each update. Moreover, we explain why it matters and how it improves your workflow. Consequently, you will know exactly what to expect after upgrading to v9.0.445.<\/p>\n

Whether you are an existing user or evaluating new tools, this guide gives you a clear picture of the release.<\/p>\n

1. RC Column Design: The Most Heavily Updated Module<\/h2>\n

Prota Software packed more improvements into RC column design than any other module. Therefore, engineers on reinforced concrete projects will notice the biggest gains. Specifically, these updates speed up design, improve transparency, and strengthen international code compliance.<\/p>\n

Effective length factors now editable in the main dialog<\/h3>\n

Engineers can now view and edit effective length factors (Beta) for columns and walls directly in the main column design dialog. Previously, this required navigating to separate settings. Now, simply tick \u201cBeta Edited\u201d and modify values inline. As a result, slenderness calculation reviews become faster and more reliable.<\/p>\n

Tie bar option accessible from column design interface<\/h3>\n

The \u201cDo not use tie bars in Columns\u201d option now lives inside the Column Design Interface. Therefore, engineers no longer leave the design environment to change this setting. Consequently, focus stays on design decisions rather than menu navigation.<\/p>\n

SNI code compliance \u2014 Pu check removed<\/h3>\n

Prota Software removed the (Pu < 0.1 Ag.fc\u2019) check from Strong Column-Weak Beam reports. Specifically, this aligns ProtaStructure with SNI 2847:2019 clause R18.7.1. As a result, Indonesian code users get compliant output without manual correction.<\/p>\n

SNI code compliance \u2014 Vu and Vn values updated<\/h3>\n

The Column Beam Joint Shear Report now applies Vu and Vn values that match SNI code requirements precisely. Furthermore, this eliminates post-processing steps for Indonesian projects. In short, both SNI fixes together ensure fully compliant column output.<\/p>\n

Eurocode shear design report improvements<\/h3>\n

The Shear Design Details section for Eurocode column design reports now provides clearer and more complete output. Additionally, the Column Shear Check Report delivers more informative results for Eurocode-based projects. Therefore, peer reviewers can trace shear calculations more efficiently.<\/p>\n

VOM column member design improved<\/h3>\n

ProtaStructure now designs column members marked as VOM (Vertical Ordinary Members) with improved accuracy. Specifically, the update better reflects code intent for these elements. As a result, seismic design workflows produce more reliable results for VOM columns.<\/p>\n

Do not use tie bars \u2014 column design interface<\/h3>\n

Engineers can now access the \u201cDo not use tie bars in Columns\u201d option directly from the Column Design Interface. Consequently, this setting no longer requires a separate menu visit. Moreover, the change keeps the design workflow uninterrupted.<\/p>\n

2. Seismic Analysis: Greater Control and Transparency<\/h2>\n

Seismic design demands precision and clear documentation. Consequently, v9.0.445 introduces several upgrades that give engineers more control over seismic checks. Furthermore, reporting improvements add transparency that peer reviewers and auditors require.<\/p>\n

User-selectable columns for seismic irregularity checks<\/h3>\n
\"ProtaStructure
Batch Design Options dialog in ProtaStructure with the “Use Selected Columns for Seismic Irregularity Checks” option enabled, defining reference column pairs 14C17 & 14C5 for Dir:1 and 14C14 & 14C9 for Dir:2.<\/figcaption><\/figure>\n

Engineers can now select specific columns or walls for seismic irregularity checks. Specifically, the software uses only these members to determine maximum and minimum displacements. Furthermore, engineers should position selected members along plan edges, perpendicular to the loading direction. When deactivated, the software defaults to all vertical members for backward compatibility.<\/p>\n

This feature is particularly valuable on irregular floor plans. Therefore, it aligns ProtaStructure with the manual judgment experienced engineers apply to seismic code interpretation.<\/p>\n

Pushover analysis: direction selection added<\/h3>\n

Engineers can now select specific analysis directions for Pushover Analysis: 0\u00b0, 90\u00b0, 180\u00b0, and 270\u00b0. Moreover, performance evaluation and reporting run independently for each selected direction. As a result, building assessments become more targeted and granular.<\/p>\n

NSR R factor breakdown in reports<\/h3>\n

Post-Analysis Check Reports now include a detailed breakdown of the R factor for NSR projects. Specifically, this adds full transparency to seismic force reduction factor calculations. Furthermore, design checks and third-party audits become easier to verify and sign off.<\/p>\n

EC8 q-factor calculation steps<\/h3>\n
\"ProtaStructure
EC8 q-factor calculation output in ProtaStructure Post-Analysis Checks Report: overstrength ratio \u03b1u\/\u03b11 = 1.3, plan irregularity adjusted q = 3.45, and elevation irregularity reduced q = 2.76 for a dual coupled wall system with Hw = 28.00 m and Lw = 7.00 m, applied identically in both seismic directions.<\/figcaption><\/figure>\n

The Post-Analysis Checks Report for EC8 models now includes detailed calculation steps for the q-factor. Therefore, engineers working under Eurocode 8 can trace exactly how the behaviour factor derives. Moreover, this supports peer review and formal documentation requirements.<\/p>\n

Torsional irregularity check: column labels added<\/h3>\n
\"ProtaStructure
ProtaStructure now displays column labels next to minimum and maximum displacement values in the A1 Torsion Irregularity Check table, helping engineers instantly identify torsion-driving columns per TBEC 2018.<\/figcaption><\/figure>\n

Column labels now appear next to maximum and minimum displacement values in the Torsional Irregularity Check table. As a result, engineers identify torsion-driving columns much faster. Furthermore, more targeted design decisions follow from this clearer visual output.<\/p>\n

3. Reinforcement Detailing: Smarter Drawings, Less Manual Work<\/h2>\n

Automated reinforcement detailing is a core strength of ProtaStructure Suite. In addition, v9.0.445 reduces manual effort further across multiple detailing tasks. Consequently, engineers produce accurate, code-compliant drawings faster than before.<\/p>\n

ProtaStructure now hatches beam reinforcement in section drawings. Therefore, rebar placement reads more clearly on construction documents. Moreover, this improvement directly addresses feedback from engineers and raises documentation quality.<\/p>\n

All stirrups now shown in beam details<\/h3>\n
\"ProtaDetail
ProtaDetail’s new “Display All Links” option in Beam \u2192 Detail Drawings \u2192 Steel Bars and Links settings enables full stirrup visibility in beam elevation and cross-section drawings, as previewed with all links rendered in red at 10\/25 spacing.<\/figcaption><\/figure>\n

Engineers can now display all stirrups in beam detail drawings. Previously, drawings omitted some stirrups for visual simplicity. Now, however, full stirrup visibility supports accurate reinforcement scheduling. Furthermore, engineers retain complete control over what appears on each drawing.<\/p>\n

Hanger bars calculation in detailed report<\/h3>\n
\"ProtaStructure
ProtaStructure now displays column labels next to minimum and maximum displacement values in the A1 Torsion Irregularity Check table, helping engineers instantly identify torsion-driving columns per TBEC 2018.<\/figcaption><\/figure>\n

Hatching now applies to staircase reinforcement section drawings, not only beam sections. Therefore, staircase details reach the same visual clarity as beam drawings. As a result, construction documentation for stair structures becomes more consistent and easier to read on site.<\/p>\n

4. Modelling and Graphical Editor: Productivity Enhancements<\/h2>\n

Beyond analysis and design, v9.0.445 improves day-to-day model building. Specifically, these changes make repetitive tasks faster and reduce geometry errors. Furthermore, right-click shortcuts put common actions one click away.<\/p>\n

Continuous drawing commands<\/h3>\n

Drawing commands now stay active until the engineer presses ESC. Previously, each element placement required reactivating the command. Consequently, placing repetitive elements on large floor plans takes significantly less time. Moreover, this change reduces interruptions during complex modelling sessions.<\/p>\n

Snap to member intersection points<\/h3>\n

A new option lets frame members snap precisely to member intersection points. Therefore, complex frame configurations carry fewer geometry errors. Furthermore, overall model accuracy improves, particularly on dense structural grids.<\/p>\n

Update end conditions from right-click menu<\/h3>\n

ProtaStructure now includes \u201cUpdate Column End Conditions\u201d and \u201cUpdate Beam End Conditions\u201d in the right-click context menu. Specifically, these options appear when engineers select columns or beams. As a result, a commonly needed action takes one click instead of several menu steps.<\/p>\n

Beam end releases explicitly displayed<\/h3>\n
\"ProtaStructure
ProtaStructure displays beam end releases M22 and M33 directly on the floor plan, helping engineers quickly identify released degrees of freedom at beam-column connections.<\/figcaption><\/figure>\n

M22 or M33 moment releases now appear explicitly at beam ends when they do not coexist. Therefore, engineers quickly verify that end conditions are correct. Furthermore, potential modelling errors surface before analysis rather than after, saving rework time.<\/p>\n

Cruciform column transfer to ProtaSteel improved<\/h3>\n

The transfer of cruciform columns to ProtaSteel now works more reliably. Moreover, the naming convention in the quantity table of materials has been improved. As a result, data handover between structural modelling and steel detailing workflows becomes cleaner and more consistent.<\/p>\n

Convert Ribs to Beam warning message enhanced<\/h3>\n

The warning message for the Convert Ribs to Beam operation now provides clearer information. Therefore, engineers understand exactly what the conversion affects before confirming. Consequently, unintended model changes during this operation become less likely.<\/p>\n

Extend frame to curved beam improved<\/h3>\n

The extend frame to member command now works more reliably when extending steel beams to curved beams. Therefore, engineers on architecturally complex steel projects experience fewer command failures. In short, this fix removes a persistent source of frustration on curved-geometry structures.<\/p>\n

5. RC Beam Design: Expanded Checks and Reporting<\/h2>\n

In addition to RC column improvements, v9.0.445 delivers focused enhancements to RC beam design. Specifically, these updates produce earlier warnings, more complete reports, and broader code coverage. Consequently, beam design workflows become more reliable across multiple international standards.<\/p>\n

EC8 5.4.2.2 shear force calculation in detailed report<\/h3>\n

The detailed beam design report now includes shear force calculations per EC8 clause 5.4.2.2. Specifically, this gives Eurocode engineers full traceability of capacity-based shear demands. Furthermore, peer review workflows that require calculation transparency benefit directly from this addition.<\/p>\n

BS Standard Pattern-9 added<\/h3>\n

Standard Pattern-9, a pattern commonly used in British Standard projects, is now available as a load pattern option. As a result, engineers on BS-code projects apply this pattern directly without manual configuration. Moreover, this addition strengthens ProtaStructure\u2019s coverage of UK market requirements.<\/p>\n

Filter for failed beams enhanced<\/h3>\n

The failed beam filter in the beam design window now works with greater precision. Therefore, engineers isolate non-compliant beams more quickly on large models. Moreover, faster identification speeds up the design iteration cycle significantly.<\/p>\n

Print marks preserved in design windows<\/h3>\n

Print marks in column and beam design windows now persist between sessions. As a result, engineers no longer reset print selections after reopening the design interface. Furthermore, selective printing workflows on large documentation sets become more efficient.<\/p>\n

NSR Clause 15.13.3.1 check for foundation and tie beams<\/h3>\n

An additional compliance check for foundation beams and tie beams now covers NSR clause 15.13.3.1. Therefore, Colombian code engineers get more thorough verification for these elements. In short, this update reduces the risk of overlooking this specific NSR requirement.<\/p>\n

6. Foundation and Punching Check Improvements<\/h2>\n

Foundation and punching check workflows receive several targeted improvements in v9.0.445. Consequently, engineers on pad footing, mat foundation, and punching-sensitive projects get more accurate checks and clearer reports.<\/p>\n

One-way shear check enhanced for Indian code (IS-456)<\/h3>\n

Three new built-up section types join the steel section catalog: steel rod section, cross (+) section, and T-section. Therefore, engineers working with custom or unconventional profiles now find these options directly in the software. Furthermore, this reduces the need for manual workarounds when designing with non-standard cross-sections.<\/p>\n

Manual deflection category control for steel beams<\/h3>\n

Engineers can now manually classify steel elements for deflection calculations: Roof Beam, Floor Beam, Cantilever, or Purlin\/Girt. Specifically, deflection limits apply based on the assigned category. Moreover, batch editing through multi-element selection saves time on large steel structures. As a result, deflection verification becomes faster and more accurate across complex models.<\/p>\n

Steel purlins and girts: chord selectability controlled<\/h3>\n

Purlin placement on the steel truss now controls which chord sections engineers can modify. Specifically, if purlins only sit on one chord, the software disables section modification for the other chord. Therefore, engineers avoid incorrect section assignments that could undermine truss design integrity.<\/p>\n

Steel braces: new built-up section types<\/h3>\n

Steel rod, cross (+), and T-sections are now also available for steel brace design. Consequently, engineers designing brace members with non-standard profiles gain the same catalog options as beam and column design. Furthermore, this consistency across steel element types simplifies cross-section selection.<\/p>\n

8. Reporting and Drawing Enhancements<\/h2>\n

Beyond analysis and design, v9.0.445 improves drawing output and report content. Specifically, these updates make construction documentation more accurate and easier to produce. Furthermore, several changes directly reduce the time engineers spend cross-referencing separate outputs.<\/p>\n

Now, however, load information appears on the drawing itself. As a result, design reviews become faster and load discrepancies are easier to catch early.<\/p>\n

Ribbed slab load transfer added to load report<\/h3>\n

Loads on ribbed slabs now transfer to the structure during 3D structural analysis. Moreover, the load report documents this transfer explicitly. Consequently, engineers working with ribbed slab systems gain full visibility over how loads flow from slab to structure.<\/p>\n

Foundation depth per element thickness in detail drawings<\/h3>\n

Detail drawings for columns and shear walls with different foundation thicknesses now show the correct depth for each element individually. Therefore, drawings no longer apply a uniform foundation depth across varying conditions. In short, this eliminates a common drawing error on projects with variable foundation levels.<\/p>\n

Column application plan preview extended to Storey 0<\/h3>\n

Ticket: #66699<\/p>\n

Image: #66699<\/strong><\/p>\n

Why These Structural Analysis Software Improvements Matter in 2026<\/h2>\n

Structural engineering firms today face mounting pressure. Specifically, they must deliver projects faster, with fewer errors, and across more international codes than ever before. Consequently, software updates that target real workflow bottlenecks matter more than ever.<\/p>\n

Consider the seismic irregularity check feature. Specifically, ProtaStructure now lets engineers choose which columns define the displacement envelope. As a result, the software aligns with experienced engineering judgment instead of forcing a rigid default. Meanwhile, continuous drawing commands and snap-to-intersection improvements may look minor at first glance. However, across a full project, they save hours of repetitive interaction.<\/p>\n

In addition, reporting improvements matter more than they appear. For example, the EC8 q-factor steps, NSR R factor breakdown, and torsional irregularity column labels all actively support peer review. Furthermore, when a reviewer can trace every calculation step, approval cycles get shorter. Consequently, design confidence goes up as well.<\/p>\n

In short, ProtaStructure v9.0.445 delivers immediate value to structural engineers. Moreover, it supports five major code environments: Eurocode, ASCE, SNI, NSR, and TBDY \u2014 all within a single platform. Therefore, engineers working across regulatory standards benefit from day one.<\/p>\n
