How to consider Mx-My interaction in concentrated plastic h

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.

Re: Bi-directional acceleration

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 directions set Recor...

Re: IDA on bridges

Hello

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

Re: simple/hinge connection

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

Re: simple/hinge connection

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.

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

Apply NTH in Two Perpendicular Direction at The Same Time

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.

Re: Find MAX from output data

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

Re: We are collecting OPENSEES User-Requirements Data

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

Not done analysis

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...
