I am analyzing a 2D RC frame building in OpenSees (tcl). The members are force based nonlinear beam column element. The frame is subjected to a lateral load and columns are expected to fail in shear. The shear behavior is incorporated through section aggregator command. But how we will know that a c...

Hi I am analyzing a 2D RC frame under some lateral load. I want to record the shear force and bending moment (at both ends and 4 integration points) for a column on which the lateral UDL is applied. I have defined the recorders as follows: recorder Element -file $dataDir/Moment1011sec3.out -time -el...

Hi I am analyzing a 4-story 2D RC frame under gravity followed by earthquake ground motion. All the columns as well the beams have same cross-section. However, I am getting "WARNING - ForceBeamColumn2d::update - failed to get compatible element forces & deformations for element: 2232(dW: << 0.201805...
