Hello,
I have a three story building with a rigid diaphragm on levels 2 and 3 (level 1 is ground). My roof is a metal deck and I want to analyze it as flexible.
I created my Nodal load cases labeled Roof-X and Roof-Y, both Seismic Load type.
I need to analyze the building with a Modal response or the Dynamic Load Case.
I want to combine my nodal loads with the Dynamic Load cases, but the Loads>Merge Load Cases is grayed out. I imagine this is because they are not both "Seismic".
How can I merge my nodal loads with the dynamic loading so that the brace frames are designed for both concurrently?
Thank you!!
