only-compression material

Post by ssami » Tue Feb 16, 2021 10:02 am

Hi everyone,

Is there any multi-linear material in OpenSees that only considers the compression behavior? if no, is there any way to model such a material?

Thanks

Use Hysteretic or MultiLinear material and set the strength values on the tension side to be very low. It's not elegant, but it should work.
