【摘要】 为了在保证框架填充墙平面外稳定的同时,尽可能减少填充墙对框架刚度的影响,GB 500011-2001《建筑抗震设计规范》中提出"钢筋混凝土结构中的砌体填充墙,宜与柱脱开或采用柔性连接"。本文针对填充墙与框架柱之间采用脱开、与框架梁之间采用钢筋拉结的构造方式,进行了模拟地震振动台试验研究。试验结果表明:填充墙与框架柱之间采用脱开的构造方式虽然能够满足"小震不坏,中震可修"的要求,但是在强震作用下,填充墙很容易发生平面外的倒塌,从而造成财产损失和人员伤亡。本文通过2片砌块填充墙体的模拟地震振动台试验,对这种构造方式下填充墙的平面外稳定性能作了相应研究。更多还原

【Abstract】 In order to ensure the out-of-plane stability of infill wall,also for reducing the influence of infill wall on the rigidity of frame,"The infill wall in masonry should be disconnected with column or adopt flexible connection with column" is putted forward in the "Code for seismic design of buildings".The shaking table test is carried out to research the disconnection of structures between infill wall and column of frame and the out-of-plane stability of infill wall using two models.The test results show that this type of structure can satisfy "No damage in small earthquake,can be repaired in middle earthquake",but in strong earthquake,out-of-plane collapse can easily occur when adopt this type of structure to infill wall,consequently may bring the loss of properties and lives.更多还原
