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?

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.

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.

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

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 files empty. Can anyone help me?
(Modal analysis is done, and the values of the period of time - which are unreasonable - are displayed).
