I have rigid diaphragms at each level with 8 moment frame beam lines in the Y direction and 4 moment frame beam lines in the X direction. I have Loads and Applied Forces report that shows the diaphragm forces at each level.
What is the best way to extract the diaphragm forces applied to each moment frame beam line? I need this to design the steel deck attachments (welds or screws) to these beam lines.
If the diaphragm is rigid then there is no internal diaphragm force reporting, so you'll probably want to use frame story shear reports to get the effective diaphragm to frame transfer forces. See: RAM Frame - Building and Frame Story Shear
