Response History Analysis of Structures with Seismic Isolation and Energy211 Dissipation Systems: Verification Examples for Program SAP2000

摘要

SAP2000 is a recently released commercial structural analysis program with211u001ecapabilities for dynamic analysis of structures with isolation and energy 211u001edissipation systems. This report presents five verification examples in which 211u001eresults obtained by SAP2000 are compared to experimental results and to results 211u001eobtained by programs 3D-BASIS and ANSYS. Three of the examples involve 211u001eseismically isolated structures, of which, one was tested on the shake table 211u001eunder conditions resulting in bearing uplift. The other two examples involve 211u001estructures with linear and nonlinear fluid viscous energy dissipation devices, 211u001ewhich were also tested on the shake table. In general, SAP2000 produced results 211u001ein excellent agreement with other analysis programs and in good agreement with 211u001eexperimental resuts, except for the case of the structures tested with nonlinear 211u001eviscous damping devices. In this case, SAP2000 underpredicted the displacement 211u001eresponse of the structure.
