带洞口框支密肋复合墙梁抗震性能试验研究
|
摘要
为了研究开洞对框支密肋复合墙梁抗震性能的影响,对1/2模型试件进行了伪静力试验研究,探讨了开洞复合墙梁的主要破坏形态、承载能力、刚度、变形能力及滞回性能,并与同尺寸未开洞密肋复合墙梁进行对比.试验结果表明:带洞口的框支复合墙梁破坏过程及模式与未开洞试件基本一致,洞口处构造柱的设置弥补了开洞所造成的承载力及刚度的降低.
A1/2-scaled frame supported multi-ribbed composite wall beam with opening is examined under pseudo-static test to study the influence of the opening,and seismic performance of the wall beam.The failure mode,bearing capacity,rigidity,deformation and hysteretic behavior are studied in comparison with one without opening.The test shows that failure process and failure mode of the specimen are consistent with wall beam without opening;and constructional columns besides the opening can make up for the decrease of bearing capacity and rigidity because of the opening.
