thanks a lot

hello，
I would like to use matlab call opensees to parameter analysis. However, I don't know how to update the model with parameters I interest, and how to automatic call opensees . Is there some examples or command about this?
thank you !

hello ， everyone I used 2D model to represent a full frame, for example, there is ten bays in the full frame, and the 2D lateral force-resisting frame is only four of the ten bays. How to model the P-Delta effect? which one is the correct in the following two methods? 1、 the 2D lateral force-resisti...

hello, everyone: I didn't use leaning columns to represent the PDelta effect in my model, I just used Geometric Transformation Command "geomTransf ColTransfType PDelta" , and the gravity load was applied to the elements(beams), I don't know whether it is right to model the P-Δ effects. Is it the onl...

Dear moshref
can you send your TCL brace buckling code to my email?
