Material nonlinearity
Material nonlinearity
(OP)
To consider only material nonlinearity in SAP2000:
-what would be the mass source for subsequent load cases after nonlinear dead load as initial case? Two options are available, default mass source and from previous load case.
-how to find the point in which materials enters plastic state and no longer elastic? Is any plot or data produced after analysis?
Cheers,

Thanks for your input. In case of shell elements, what stress I need to plot against time using time history analysis? How about frame elements? To plot any value against time, then the required load case must be in dynamic state to be able to plot the stress/force vs time.

You can plot Von Mises stress.
