Non linear inelastic time history analysis in SAP2000
Non linear inelastic time history analysis in SAP2000
(OP)
I am Modelling a 3 D 10 Storied Steel structure( Building) for seismic loading. I need to place dampers in the structures and the responses of the building are of critical importance. When i run a Non linear time history direct integration analysis for the structure, the responses i observe are in the inelastic range for the steel members, but the frame elements i choose were in the elastic range. So i get unreal responses for the structure. How can i get to account for inelasticity in my frame elemts and is SAP 2000 capable to handel Non linear inelastic analysis with responses accounting for inelasticity in the frame elements.

1.After the plastic hinge is formed all of the non linearity will be in the hinge formed, will the length of the hinge matter?
2. Are the displacements from a structure where plastic hinges are formed accurate enough.
3. My current research is on the placement of the passive energy dissipation devices, can the results from SAP 2000 Non linear inelastic analysis serve the purpose, are the results debatable.
