摘要

某些老建筑的改造加固往往涉及较为复杂的问题,对这些结构进行非线性地震反应分析有时比新建结构更为困难。基于ABAQUS平台对某二次改造建筑结构进行了详细的地震弹塑性分析,并针对其中关键耗能器件——软钢阻尼器从不同角度进行了对比研究,详细讨论了阻尼器在罕遇地震下的耗能能力,对初步设计方案进行综合评价并给出修改建议。
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 of the building’s preliminary design and some proposed amendments are formed as well.
