I've used one ElasticPPGap material and one Hysteretic material in series. After the gap, the combined stiffness of the two materials shou...

Re: How to create spring and attach to it a zeroLength elem

Hi, I have once developed a compression only multilinear material in OpenSees by just modifying the existing multilinear material. I can give you the source file (.cpp) and also the .dll file but don't know whether the .dll file will work on your system. I am using 64bit Windows 8.1. But once you ha...

From python you can then load this mat file from scipy.io import loadmat, savemat var = loadmat('myvar.mat') # 'var' will be a 'dict' {}, so extract your matr...

PM Hinge interaction curve

Hi, Is there any option in Opensees so that I can input P-M interaction curve for Hinges. Actually I want to model a masonry column. But due to unavailability of axial shear interaction model I want to convert the shear forces to equivalent moment which will interact with the level of axial force pr...
