【摘要】 对在连梁处设置软钢剪切型阻尼器的某框架-剪力墙结构在罕遇地震作用下的抗震性能进行了研究。分析结果表明,仅在底部加强区设置约束边缘构件时,结构不能满足大震不倒的设防要求,该结构剪力墙中约束边缘构件应通高设置,抗震构造措施提高后的结构能够达到大震设防目标,剪力墙累积受压损伤得到有效减小,各层连梁中的阻尼器均起到了较好的消能减震作用,提高了结构的整体抗震性能。更多还原

【Abstract】 Seismic performance analysis is carried out for a frame shear wall structure subjected to major earthquake,and with installation of mild metallic shear type damper in the coupling beams. The analysis results show that while restrained boundary elements set in reinforcing area on the bottom of shear wall,the structure can’t meet the requirement of no collapse in rare earthquake,and setting restrained boundary elements along the whole height of the shear wall is necessary. After the aseismic structural measures are improved,the structure reach the rare seismic fortification target. Accumulated compressive damage of shear wall is mitigated effectively. Coupling beam dampers on each floor dissipate energy and improve the seismic performance of structure greatly.更多还原
