Dear community good morning,
On the below steel structure where only vertical loads applied (self weight (DEAD) + piping elements (DEAD)), when i post processing the model , during the combinations where wind and seismic loads applied, i see that on the reactions field on the pin points supports (4 corners), i have very less reactions on x and z axis. See below the relevant screenshots.
Also below you can see how i have already set the parameters in wind and seismic responce menus.
Is there anything that i should change?
Thank you very much in advance for your valuaable support.
Kind Regards,
Once you have a question specific to some model, always attach that model for the investigation.

Wind loads are low, because it is generated on open structure, so you should not expect high reactions. For the seismic loads, the mass above the ground level is quite low, so that leads to low horizontal reactions too.
On a separate note, compression only springs should not be used with dynamic response spectrum analysis. A more detailed explanation can be found here: Response spectrum analysis with compression only springs - RAM | STAAD Wiki - RAM | STAAD - Bentley Communities
