1、第46卷第lO期2015年lO月建筑技术ArchitectureTechnology·941·Vb1.46No.10Oct.2015带板双连梁与带板单连梁的对比分析及工程应用王秀存,张海2,孙益欢2,田慧(1.天津国民地产有限公司,300380,天津;2.天津城建大学土木工程学院,300384,天津;3.天津城市建设管理职业技术学院建筑工程系,300134,天津)摘要:通过有限元分析软件ANSYS分别建立带板双连梁和带板单连梁联肢剪力墙结构模型,并在结构顶点施加水平荷载,研究带板双连梁与带板单连梁在水平荷载作用下的受力性能。分析带板双连梁的连梁、墙肢内力、顶点最大位移、破坏形态、结构极
2、限承载力及延性等特性,并与带板单连梁进行对比研究。研究结果表明:带板双连梁在不影响水平力传递的基础上,能有效降低连梁剪力和弯矩,并对改善墙肢的受力有着显著作用;与带板单连梁相比,带板双连梁的极限承载力与抗侧刚度有一定的降低,但位移廷性有较大提升。最后通过工程实例,验证了有限元计算分析的结论,确认了双连梁结构形式在工程实际中的有效陛,为以后结构设计提供了参考。关键词:带板双连梁;墙肢内力;位移延性中图分类号:TU755文献标志码:B文章编号:1000—4726(2015)10.0941.06COMPARISoNANDENGINEEluNGAPPLICATIoNoFPLATE.SUPPoR
