Why are the bars in Metal 3D assigned a moment coefficient equal to 1 when I have told the Portal Frame Generator to generate the data for the lateral buckling check? |
The Portal Frame Generator does not know what the moment diagram of the frames generated in Metal 3D will be like; therefore a default value of 1 is provided. Users must change this value to that indicated in the selected code. Regarding the braced distance, the program does generate the data correctly. |
