I did a nonlinear static analysis (Pushover) on a RC bracing moment frames with 2 spans and 3 levels (2D model) using SeismoStruct software.
Beam-Column Element types used is ==> Inelastic force-based plastic hinge frame element type- infrmFBPH
And then I make the same model in SAP2000 software with plastic hinge of the type Fibre P-M-M
The two curves (Pushover curve) are almost identical (Seismo and sap2000).
My question is as follows,
- Did I do the modeling correctly with regard to the plastic Hinge?
-In the three-dimensional model (3D) does not give us convergence in the results. Is the problem in coupling?
thanks in advance
