The analytical model SAP2000 constructed for this study uses the exact same size as the steel structure used in actual experiments. As SAP2000 is an engineering structure used to design package software, we only need to input data of the various size, cross section of figured steel and material characteristic. We can further use the build-in link to simulate the motion behavior of spherical sliding isolators including the effective stiffness and the friction coefficient.
