Seismosoft | Earthquake Engineering Solutions

Hello all,

I was wondering if SeismoStruct can be used to simulate/model composite materials such as Structural Insulated Panels (SIPs)? SIPs are made of two OSB boards and a foam core continuously bonded together. I need to model a 1.2 by 2.4m tall panel with the overall thickness of 165 mm. The thickness of the face sheets (OSB) is 11mm.

Thank a lot!

Hi umdelija,

If you are interested in the inelastic response of SIPs, I suspect that the only manner in which you will be able to model it in SeismoStruct is by calibrating an equivalent frame element using experimental results for SIPs (or results from detailed nonlinear shell elements analysis of SIPs).

If, instead, you are interested in considering only the elastic response of the SIPs, then you may compute the horizontal stiffness of such panels through hand-calculations (in the same way that you would calculate for an infill panel or a slab), and then introduce braces calibrated to have the same stiffness.

Best,

Rui
