Apply simple loadings on a cantilever with elastic materials in order to figure out what each column represents.

Dear Professor, I made a simple test with elastic element of elastic material, but there was no output result. With fiber section, it is the same as mine. Is there any other method？

dear,
I use the " recorder Element - the file $dataDir/ElementDeformation49. Out 49 section 1 - ele deformation " to output section deformation, why there are four column data? What do they stand for?

Please help me.

Hi guys. Why does the section moment—curvature analysis program on the OpenSEES official website fail to run？ When I run it, I get the following ： ##################################### Estimated yield curvature: 0.000126984126984127 invalid command name "MomentCurvature" while executing "MomentCurva...

Thanks a lot, this is very inspiring for me

dear : When I analyzed the seismic response of the cable-stayed bridge, the following results appeared. #################################################### WARNING BandGenLinLapackSolver::solve() -factorization failed, matrix singular U(i,i) = 0, i= 106 WARNING NewtonRaphson::solveCurrentStep() -th...

dear mhscott: I'm very sorry to bother you again. After I modified the material, the following error appeared again. Is it the error of mass and gravity? ######################################## WARNING - ForceBeamColumn3d::update - failed to get compatible element forces & deformations for element:...

Thank you very much for your reply, I will try again with a different material.

Hi, everyone： I am building a cable-stayed bridge with two towers , and analyzing its seismic vulnerability, the piers and towers are nonlinearBeamColumn element,and they are made of fiber sections. The following error occurred in the gravity analysis stage. #########################################...
