Re: P-Delta Effects for Models With Elements which doesn't include Geometric Transformation
Hi Yes, i assigned masses to the leaning column. But still i keep getting imaginary Eigenvalues. IS the leaning column method valid for 3D models as well? mine is a 3d Model, but i assigned a leaning column to the first frame of the building only. "Imaginary eigenvalue can be because the leaning col...

Re: p-delta effects
Hi,
Is Adding leaning column to simulate P-dela effects done ony in 2D analysis?

P-Delta Effects for Models With Elements which doesn't include Geometric Transformation
I have Modelled a Modular building in Opensees. This Includes Boxes( Modules-made of shell elements) connected with two node link elements to form a building as shown below. We also developed an experimental model of the same and noticed the results for the top displacement. I could notice that ther...

Modelling Aluminium frame
Hi everyone, How do we model an Aluminium frame in opensees for Nonlinear analysis? My concern is how to choose Material for it. Obviously we don't have a straight forwad code for it. But What Uniaxial Material do you suggest to be used to Model the Aluminium Material? Even if we use a Multilinear U...
