I'm trying to simulate a precast segmental column in 2d space for quasi-static test. I used dispBeamColumn eleemet with fiber section for the column,and truss element for the prestressing tendon, and zerolength element with conpression-only material for the segment-to-segment joints,Unfortunately,it...

Hello, i got a problem when i simulate post-tensioned precast segmental column, what i use for prestressing tendon is truss element ,and the material is ElasticPP, but the analysis failed ,when i change the material into other material (concrete01), it works , how can i correct the model ? thank you...

Hello, I'm trying to simulate a precast segmental column with a hollow section in 3d space. I used fiber section for the column. Unfortunately,it doesn't seem to work properly. I take the message: WARNING BandGenLinLapackSolver::solve<>-LAPACK routine return 49 WARNING NewtonRaphson::solveCurrentSte...
