Steel Residual Stress

[ysir]

Hey all,

I am now analyzing the steel frame that consider the steel residual stresses due to manufacturing.
I have look up many examples to see if there is way to incorporate this. However, I couldn't find any way to do this.
I would like to incorporate the residual stress distribution such as ECCS distribution where it has triangular shape i.e. non-uniform across the section.
Does anyone have any ideas how to do this.

Thanks

Hey,
Did you find information to consider the steel residual stresses in an Opensees model?
I would like to incorporate the residual stress in a tube section due to manufacturing.
Thank you

Try initial stress uniaxial material: http://opensees.berkeley.edu/wiki/index ... s_Material
