SAP2000 Change the value of gravity.

SAP2000 Change the value of gravity.

SAP2000 Change the value of gravity.

(OP)
Hi, I'm new to SAP2000 and hoping to use it to perform a structural analysis on custom concrete-like materials under different gravity values i.e. on the moon and mars.

Is this possible in SAP2000? Is there a way to change the value of gravitational acceleration so that I can simulate these structures, i.e. change it from 9.80665m/s2 to 1.622m/s2 for the moon and 3.711m/s2 for mars - or any custom value I want to enter. Any help and the steps to do this would be much appreciated!
Thanks

RE: SAP2000 Change the value of gravity.

I would imagine there is a way to do that. Have never come across it.

I think it's possible to fake out SAP and just apply the ratio of 1.622/9.81 = .165 to your "Load Pattern" self weight multiplier.
