How to merge the results from sub-frame FE floor analysis and results from the 3D building analysis? <\/span><\/span><\/h1>\n
 <\/span><\/span>After a model is completed, a building analysis is mandatory which will generate results for G and Q (including the pattern cases of G and Q) as well as lateral load cases. This will be followed by FE Chasedown analysis and only then the results can be merged.<\/span><\/span> <\/div>\n
<\/span><\/span> <\/div>\n
<\/div>\n
\"Alert\" <\/p>\n
Note that these options will only be available when FE chasedown analysis has performed for all storeys from top to bottom. (Select All Storeys > Check "Include Upper Storey Column Loads" > "Floor Mesh and Analysis")<\/i>.<\/span><\/span> <\/div>\n

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

Are they added up together simply by superposition?<\/span>
<\/h1>\n
When FE Analysis results are merged, ProtaStructure completely replaces unfactored load case results for G and Q (including the pattern cases of G and Q) of Building Analysis with the corresponding loadcase results of G and Q from the FE Chasedown analysis. This means that the final merged result will consist of gravity load cases (G & Q) derived from FE chasedown analysis while the results of lateral load cases will be from 3D building analysis.  <\/span><\/span>
<\/span><\/div>\n
\n
\"Alert\"Hence, the merging of results is not superimposition as we understand it, i.e. we are not discarding the smaller values of say G loadcase of Building Analysis and replacing it by a larger value of FE Analysis.<\/span><\/span><\/span><\/div>\n
However, ProtaStructure always uses superposition to generate the results for design combinations.<\/span><\/span>  <\/span>As such, if a conservative design is desirable, such as for design a transfer beam, it is possible to consider both Building Analysis and FE Chasedown analysis in the design of the members by :<\/span><\/span><\/div>\n<\/div>\n
    \n
  1. Run Building Analysis which will generate both gravity and lateral results<\/span><\/span>
    <\/span><\/li>\n
  2. Perform beam and\/or column design.<\/span><\/span>
    <\/span><\/li>\n
  3. Run FE Chasedown which will generate different set of gravity loadcase results
    <\/span><\/li>\n
  4.  <\/span><\/span>Merge FE Chasedown results with Building Analysis results (by checking option "Merge Column \/ Beam Results….")<\/span><\/span>
    <\/span><\/li>\n
  5. Perform beam and\/or column design using the design option to increase steel only when the previous steel is insufficient. Previous steel if sufficient would not be changed at all.
    <\/span><\/li>\n
  6.  <\/span><\/span>For example, if the mid-span moment of the beam for FE Chasedown is found to be larger than that obtained from Building Analysis, the steel will be increased.<\/span><\/span>
    <\/span><\/li>\n<\/ol>\n

     <\/span><\/span>We will use a simple 2 storey structure similar to model used in the axial load comparison model as illustration.<\/span><\/p>\n
