【摘要】 阐明新型阻尼填充墙的构造和原理;对阻尼填充墙的基本构成单元、单层单跨的框架阻尼填充墙、框架阻尼填充墙整体结构的减震性能进行综合分析,研究结果表明,阻尼填充墙通过框架柱带动砌体单元往复剪切阻尼层滞回耗能,其耗能性能稳定,耗能效果好;阻尼填充墙能为结构提供一定的抗侧力和抗侧刚度,但其对结构的刚度效应和约束效应较普通填充墙大为削弱,避免造成柱受剪破坏、结构延性及侧向变形能力变差等不利影响;在结构中设置阻尼填充墙,结构周期折减的幅度远小于设置普通填充墙的情况,而且阻尼填充墙耗散输入结构的部分地震能量,减小结构构件的非线性耗能,减轻结构在地震中的破坏,具有良好的减震效果,且墙体自身不破坏.更多还原

【Abstract】 The construction and principle of new-type damped infill wall are expounded.And the aseismic performance of damped infill wall(DIW)is analyzed comprehensively from several aspects,including the fundamental units of DIW,single story-single bay DIW-frame and DIW-frame structure,etc.The results indicate that the DIW contributes to the hysteretic energy of structure with its masonry units shearing the damped layer circularly,achieving stable energy dissipation performance and excellent energy dissipation effect.DIW is capable of enhancing the lateral force resistance capacity and the lateral stiffness of structure;but its stiffness effect and confined effect is much weaker than that of conventional infill wall,which prevent DIW from causing the adverse effects,such as shear failure of column,deterioration of structural ductility,etc.Compared with setting conventional infill wall in structure,setting DIW makes much smaller reduction amplitude of structural period.Furthermore,DIW dissipates partial energy inputed into structure during earthquakes,reduces the nonlinear energy dissipation of structural members,relieves structural members’ damage and plays a good role in aseismic effect with itself hardly damaged.更多还原
