Different Type of RC Beam<\/span><\/h1>\n
They are different types of reinforced concrete beam.  The icons are accessible from the <\/span>Modelling <\/span><\/b>tab, <\/span>RC Beam<\/span><\/b> drop down list. <\/span><\/div>\n

Foundation Beam <\/span><\/h2>\n
A foundation beam is a reinforced concrete beam modelled in <\/span>ST0<\/span><\/b>, which is always the foundation level.  <\/span><\/div>\n
Hence, this icon will only be available if ST0 view is made current and active by double clicking on this level in the <\/span><\/span>Structure Tree<\/span><\/b>. <\/span><\/span><\/div>\n
To model a foundation beam : <\/span><\/div>\n
\n
1. <\/span><\/span>Switch to the foundation storey (St: 0<\/b>)<\/span><\/div>\n
2. Click Modeling <\/b>tab > Beam dropdown > Foundation Beam<\/b> <\/span><\/div>\n
3. The beam property window will be opened<\/span><\/div>\n
4.  Create beam as stated in the next section "<\/span>Defining a New Beam<\/span><\/b>"<\/span><\/div>\n<\/blockquote>\n
The purpose of a foundation beam can be : 
<\/span><\/div>\n
1.  To insert a<\/span> Strip Footing<\/a>.<\/div>\n
2.  Modelled with raft foundation slabs to stiffen or strengthen it.  
<\/span><\/div>\n

    Tie Beam <\/span><\/span><\/span><\/h2>\n
    \n
    Foundation tie beams can be defined in ProtaStructure to provide a horizontal connection between two columns at the foundation levels preventing lateral movements and relative displacements, especially if there are pad footings. <\/span><\/span>Tie Beam can only be created if <\/span>ST0<\/b>, i.e. foundation level, is made current & active. <\/span><\/div>\n
    <\/p>\n
    \"Alert\"<\/div>\n
    Important! <\/b> <\/span><\/div>\n
    Foundation Tie Beam design is currently only implemented for Turkish Seismic Code (TBDY 2018) & American ACI318 Code.  <\/span><\/div>\n
    If you are using any other design code, do not model a tie-beam.  You may use a foundation beam instead. 
    <\/span><\/div>\n

    <\/span><\/div>\n

     To create a tie beam:<\/span><\/div>\n<\/div>\n
    \n
    \n
    \n
    1.  Switch to the foundation storey (St: 0<\/b>)<\/span><\/div>\n
    2. Click Modeling <\/b>tab > Beam dropdown > Tie Beam <\/b><\/span><\/div>\n
    3. The beam property window will be opened<\/span><\/div>\n
    4.  Create beam between 2 foundation columns, as stated in next section "<\/span>Defining a New Beam<\/span><\/b>"<\/span><\/div>\n<\/div>\n<\/div>\n<\/blockquote>\n
    \n
    Once inserted, their design will be carried out considering the axial forces on the columns or walls they are connected to. <\/span><\/span>
    <\/div>\n
    <\/div>\n
    The axial force considered in the design of tie beam is calculated with this equation in Turkish Code : <\/span><\/span><\/div>\n

    <\/div>\n

    Normal Beam<\/span><\/span>
    <\/span><\/h2>\n
    A Normal Beam is a reinforced concrete beam created in storey 1 and above (i.e. not foundation level).  <\/span><\/div>\n<\/div>\n
    To create a tie beam:
    <\/span><\/div>\n
    \n
    \n
    1.  Switch to Storey 1 (St: 1) or above <\/span><\/span><\/div>\n
    2. Click <\/span>Modeling <\/span><\/b>tab > Beam dropdown ><\/span> Normal <\/span><\/b><\/span><\/div>\n
    3. The beam property window will be opened<\/span>
    <\/span><\/div>\n
    4.  Create beam as stated in the next section "<\/span>Defining a New Beam<\/span><\/b>"<\/span><\/div>\n<\/blockquote>\n<\/div>\n

    Wall Coupling Beam<\/span>
    <\/h2>\n
    Wall Coupling Beam are used to link shear walls for increased stiffness to resist large lateral loads, i.e. seismic loads.   This beam type can only be created in Storey 1 & above, i.e. as a superstructure beam.   <\/span><\/div>\n
    \n
    <\/p>\n
    \"Notes\"<\/div>\n
    Specific checks are performed to validate this system to ACI seismic code. <\/span><\/div>\n
    This consequently decrease overturning effect and improve overall stiffness of a building system.
    <\/span><\/div>\n

    <\/span><\/div>\n

    \n
    To create a Wall Coupling Beam:
    <\/span><\/div>\n
    \n
    \n
    1.  Switch to Storey 1 (St: 1) or above <\/span><\/div>\n
    2. Click <\/span>Modeling <\/span><\/b>tab > Beam dropdown ><\/span> Wall Coupling Beam<\/span><\/b><\/span><\/div>\n

      \n
    1. Use different cracked section properties as dictated by different seismic codes.<\/span><\/li>\n
    2. Assess and check the connected wall panels to see if they act as a coupled wall or not.<\/span><\/li>\n
    3. Currently, there is no special design nor detailing for coupling beam –  it will be designed and detailed as a normal beam.<\/span><\/li>\n
    4. Details are shown in the Post Analysis Checks<\/b> Report > Wall \/ Frames Effect Check<\/b>.<\/span><\/li>\n<\/ol>\n<\/div>\n

      Defining a New Beam<\/span><\/span><\/span>
      <\/h1>\n
      Before inserting a Beam member, its reference axes should be defined.  <\/span><\/div>\n
      <\/div>\n
      <\/div>\n
      Beams are defined by two axis intersection points (insertion points)  defining the start "I" and end "J" of the member. Hence for beams, 3 axes are needed to create the 2 insertion points. <\/span><\/span><\/div>\n
      <\/div>\n
      To define a new <\/span>Reinforced Concrete Beam<\/span><\/b> member:
      <\/span><\/div>\n
        \n
      1. Display the storey level in the drawing area which will contain the beam. 
        <\/span><\/li>\n
      2. Click the <\/span>Beam Icon<\/span><\/b> from the reinforced concrete category under the <\/span>Modelling<\/span><\/b> ribbon<\/span><\/li>\n
      3. Pick the Beam Type<\/span><\/b> as stated in the above section<\/li>\n
      4. Edit the fields in the <\/span>Beam Properties<\/span><\/b> box. For example, users can edit the label of their beams in the <\/span>Label<\/span><\/b> field (max. 11 characters), modify the section dimensions and its eccentricities. 
        <\/span><\/li>\n
      5. To insert the beam, locate the insertion points in the plan view drawing area, or the 3D view. Click on two axes intersection points to insert the beam. <\/span><\/li>\n<\/ol>\n
        \n

        Defining a New Beam without Reference Axis
        <\/span><\/h1>\n
        A new beam can also be defined without necessity of predefining the main reference axes that should run along the beam. However, true potential end points or the axes that will potentially generate end points, must be defined first. The following figures illustrate this. 
        <\/span><\/div>\n<\/div>\n

        <\/span><\/div>\n
        A new beam will be defined between  Point 1 and Point 2. These points are true potential end points of the beam (<\/span>I<\/span><\/i> and <\/span>J<\/span><\/i>) and they are created by other axes, rather than a non-orthogonal axis that the beam is supposed to defined on. <\/span><\/div>\n
        <\/div>\n
        <\/div>\n
        When the new beam is drawn by picking the Point 1 and Point 2, a new axis will also be generated. This new axis is given a unique name preceded <\/span>"<\/span><\/i>@"<\/span><\/b> sign. The label of new axis can been seen on <\/span>Structure Tree.<\/span><\/b><\/div>\n
        \n
        \"Info\"This feature is very useful but must be used with caution. If it is intended to define a beam by traditional method over an already existing axis, you must be sure to snap to the real intersection point. Program may draw the beam but not on the axis intended. Snapping options can be adjusted via <\/span>Display Settings<\/span><\/b> <\/span>> Object Snap ><\/span><\/b> in <\/span>Display <\/span><\/b>ribbon. <\/span><\/span><\/div>\n<\/div>\n

        Editing an Existing Beam 
        <\/span><\/h1>\n
        In order to edit an existing beam: 
        <\/span><\/div>\n
          \n
        1. Select an existing beam. 
          <\/span><\/li>\n
        2. Right-click and select <\/span>Properties<\/span><\/b>.
          <\/span><\/li>\n
        3. Modify the fields such as <\/span>Label<\/span><\/i><\/b>, <\/span>"<\/span><\/b>b<\/span><\/b><\/i>",<\/span><\/b> etc. in the<\/span> <\/span><\/i>Beam Properties<\/span><\/b> box. 
          <\/span><\/li>\n
        4. Press the "Update" button in the form. 
          <\/span><\/li>\n<\/ol>\n
          Right-clicking on any one of the <\/span>"<\/span><\/b>b<\/span><\/b><\/i>", "<\/span><\/b>e<\/span><\/b><\/i>" "<\/span><\/b>h<\/span><\/b><\/i>",<\/span><\/b> or <\/span>"<\/span><\/b>e-z<\/span><\/b><\/i>"<\/span><\/b> fields will load a list of commonly used values that may facilitate data entry. 
          <\/span><\/div>\n
          You can repeat this process to as many members as you wish. One member at a time can be edited by this method. <\/span><\/div>\n
          If you want to update several beams at once, you can use<\/span> Beam Table<\/span><\/b> in the right-click menu <\/span>Properties<\/span><\/b> in <\/span>Beam<\/span><\/b> ribbon. <\/span><\/div>\n

          Beam Properties<\/span><\/h1>\n
          Beam Properties<\/span><\/b> will be loaded when the <\/span>Beam <\/span><\/b>option in the<\/span> Modelling<\/span><\/b> ribbon is selected. A new beam can be defined by arranging  the fields in the form and then by picking two axes intersections in the plan view window. <\/span><\/div>\n
          The <\/span>Beam Properties<\/span><\/b>  form can also be accessed after selecting an existing beam an then by right-clicking and choosing<\/span> Properties<\/span><\/b> in the shortcut menu. <\/span><\/div>\n

          4. "<\/span>e-z<\/span><\/i><\/b>"  is the eccentricity of the beam along its section depth which measured the distance between top of the beam and the slab top reference level. Generally, all beams are inserted to stay below the slab reference level, having<\/span> "<\/span><\/b>e-z = 0<\/span><\/b><\/i>"<\/span><\/b>. If you need to define beams spanning above the slab top edge, then <\/span>e-z<\/span><\/b><\/i> <\/span><\/b>will be a non-zero value.

                                2. If a mixed selection is made involving beams, only selected beams can be listed using "<\/span>Beam Table<\/span><\/i>" option in shortcut menu. If some of the beams are selected, only the selected beams will be listed using "<\/span>Properties<\/span><\/i>" option in the shortcut menu. <\/span><\/li>\n
                                3. If "<\/span>All Storeys<\/span><\/i>" option is checked in "<\/span>Beam Table<\/span><\/i>", other beams defined in the Graphic Editor are displayed even they do not belong to current storey.

                                  The method for defining Curved Beam Members is as follows:-
                                  <\/span><\/div>\n<\/div>\n
                                    \n
                                  1. Press the "<\/span>Beam<\/span><\/i>" button located in "<\/span>Modelling<\/span><\/i>" ribbon.
                                    <\/span><\/li>\n
                                  2. Right-click and select "<\/span>Properties<\/span><\/i>". When the "<\/span>Beam Properties<\/span><\/i>" form is loaded. 
                                    <\/span><\/li>\n
                                  3. Select "<\/span>Curved Beam Insertion<\/span><\/i>" from the insertion method <\/span>. 
                                    <\/span><\/li>\n
                                  4. Pick the first and second points. The first and second points defined in this way will be the "<\/span>I<\/span><\/i>" and "<\/span>J<\/span><\/i>" points of beam respectively. 
                                    <\/span><\/li>\n
                                  5. Press "<\/span>F2<\/span><\/i>" on keyboard to enter the chord offset (<\/span>h<\/span><\/i>) of the curved beam or you can simple define the chord offset (<\/span>h<\/span><\/i>) of the curved beam by picking a point on the graphical editor plan view. <\/span><\/li>\n<\/ol>\n

                                    Defining Beams out of Columns Insertion Points
                                    <\/span><\/h1>\n
                                    "<\/span>I<\/span><\/i>" and "<\/span>J<\/span><\/i>" ends of beams in ProtaStructure Model must actually be defined at the same insertion point with column or wall insertion point. This assures the continuity of analytical model. However, due to grid system complexities, architectural limitations or possible user errors, end points of the beam may not coincide with column that is supposed to support it.
                                    <\/span><\/div>\n
                                    If the beam end (<\/span>I<\/span><\/i> or <\/span>J<\/span><\/i>) is defined on another point within the physical borders of the column section, a <\/span>rigid link<\/span><\/i> is automatically created by the analysis engine and the continuity is granted for. 
                                    <\/span><\/div>\n
                                    \n
                                    <\/p>\n
                                    \"Notes\"<\/div>\n
                                    This feature helps to prevent user errors or to work around some geometrical necessities. In normal conditions do not create your models relying on rigid links. Always work with \u201cnode-to-node\u201d concept in mind.<\/span><\/div>\n

                                    <\/span><\/div>\n<\/div>\n

                                    To illustrate this, below is an example where the column insertion point is different from the beam insertion point. in this case, the beam is defined near the column border.
                                    <\/span><\/div>\n

                                    <\/span><\/div>\n

                                    <\/span><\/div>\n
                                    The analytical assumption is as shown below. A rigid link is automatically created to "catch" the beam.
