【摘要】 减隔震结构在日本的应用已较为成熟,2011年东日本大地震后,通过震后调查发现减隔震建筑整体表现卓越,有效地保护了生命及财产安全,达到了预期的设计目标。但也发现减隔震建筑有亟待改进之处,如需要进行多目标设计和极限状态设计,以便在各种工况下均能发挥作用,同时也应该在减少残余变形和减少竖向地震动响应等方面予以考虑。对东日本大地震中减隔震建筑的性能表现进行探讨,得到的一些经验和借鉴,有利于未来减隔震结构的发展。

【Abstract】 Investigation of the performance of seismic energy dissipation structures in the Great East Japan Earthquake can be helpful for future development of the energy dissipation structure. Based on field investigation,energy dissipation structure had shown remarkable performance in safeguarding lives and properties during extremely intensive earthquake,reaching expected design objective. However,it is also necessary to make improvements in the energy dissipation structure. For example,multi-level multi-objective design and ultimate state design are needed so as to make the structure more effective in various cases.Meanwhile,reductions in residual deformation of energy dissipation element and in vertical earthquake response should also be taken into consideration.
