( Shanghai Xian DaiArchitectural Design (Group) Co., Ltd., Shanghai 200041, China)Abstract: In some projects of retrofitting of the old buildings, much more complicated problems are involved, and nonlinear seismic analysis to these projects may be more difficult than the new structure. Based on the ABAQUS platform, detailed elastoplastic seismic analysis is performed to Shanghai Shendu building, and in which the key energy-consuming device-low yield-point steel damper is studied comparatively from different aspects, and its energy dissipation capacity under the rare earthquake is discussed in detail. In addition to this, there is a comprehensive assessment ofthe building's preliminary design and some proposed amendments are formed as well.
Keywords: ABAQUS; elastoplastic; low yield-point steel damper; energy-consurmng
