Wind load from Equipment on a structure
Wind load from Equipment on a structure
(OP)
I am trying to model/analyze a structure on RISA 3D. I built the structure which has some equipment on it. I have applied a downward load due to the equipment. Afterward I built walls to resemble the equipment and gave the material 0 density so weight was not factored in since I already accounted for it. I wanted to model the equipment in order to apply a wind load to the equipment and to the structure. Is what I did an appopriate method? I was not sure how to represent the walls fastened to the structure so i fixed them in their locations.
Additionally, I have been putting grating in my models however i do not model it i just apply a deadload for the weight it would apply so that it is factored in. Would it be better to apply plates to the top of my structure?
Any helpful tips from people who do similar modeling would be excellent.

This may be the result of some un-realistic parameters for the wall. If so, then just go to the Solution tab of the Global Parameters and un-check the box which includes P-Delta for wall panels. Note: the P-Delta effect will still be considered for the beam and column members, just not the wall panels.
If you think the wall panels may have a genuine stability issue, then you should take a look at the parameters which define that wall (thickness and material properties) and see if those should be changed.
