Dear SelimGunay

Thank you.

Hello

I have modeled a concentrated plastic hinge using the method which has introduced in report No.152, Ibarra and Krawinkler (2005).
But I don't know how to model or make Mx-My interaction in that model. So I need some help.

Hi everyone I want to run a nonlinear time history analysis. But I want to apply both longitudinal and transversal accelerations simultaneous. I have done that this way. Is that true? set iGMfact "1.82 1.82"; # ground-motion scaling factor set iGMdirection "1 3"; # ground-motion ...

Hello

Is there anyone who has an OpenSees example for 3D IDA analysis? Thank you if you share it.

In this case, the definition of 2 nodes in j is sufficient. However, with the three nodes, the above modeling can also be performed.

Hi,

you should define 3 nodes at j node. So in the definition of the equaldof command, the middle node will be common for beam 1 and 2.

Thank you

Good time
In the following of the above question, how should we define the analyze command?

Thank you so much Dear selimgunay

Hello Everyone

I want to accomplish NTH (nonlinear time history) analysis in two perpendicular directions at the same time (i.e. x and y directions). But I don't know how to do this. I would be appreciated if anybody helps me in this field.

Dear Selimgunay

The solution was the one you said and the problem was somewhere else. Sincerely thank you for your reply.

If you remove $ between incr and i, the problem with your loop will be resolved.

Dear Hibahashim

you can do it simply by using MATLAB or Excel.

Thanks to this post, which is designed to meet the needs of users. I must say that examples of the bridge are very rare.

Hello I've modeled a three dimensional reinforced concrete bridge using zeroLength element at the base of columns. The problem is that while there is no error, there is no analysis too. The proof of this is doing the total analysis (gravity and nonlinear dynamics) in one second and also being output...
