Thanks so much.

hi, I have a problem. I used two types of models to make the analysis pushover. In the first model I used nonlinearBeamColumn element in the second model I used dispBeamColumn element. The pushover curve obtained with the second model is about double compared to the first model. is such a thing poss...

Hi, I have a problem.
What are the values alpha ​​to be inserted in
the command constraints Penalty?
Thanks.

Thanks so much

The rotation is the chord rotation than the inflection point where the shear stress is zero (for example in the column). If I have a portal shear type the chord rotation is calculated as the difference in displacement between the two nodes divided by the length of cut. The cutting length is about ha...

Hi, I have another question.
How to calculate the rotation of the element to the rope?
thanks so much.

thanks so much

Hi, I have a problem. Below is the my problem: recorder Element-xml-$ datadir / FCol.out-time-ele 1 basicForces What are basicForces? It refers to a section of the element or a point of integration? recorder Element-xml-$ datadir / FCol.out-time-ele 1 basicDeformation What are basicDermation? It ref...

Thanks for your reply.

Thanks for your reply.
So how can I solve the problem of convergence?
Thanks.

Hello, I have a problem. I'm doing a nonlinear dynamic analysis with accelerogram. During the analysis, I get: DirectIntegrationAnalysis::analyze() - the Algorithm failed at time 20.16 OpenSees > analyze failed, returned: -3 error flag WARNING: CTestEnergyIncr::test() - failed to converge after: 10 ...

Thanks so much.

Thanks for your reply. For example, if the command object in the analysis are: constraints Lagrange ; numberer RCM; system BandGeneral ; test NormDispIncr 1.0e-8 6 ; algorithm Newton; integrator LoadControl 10; analysis Static; eigen frequency 3 analyze 0.1; For the following example which is the ty...
