在剪力墙结构设计中经常遇到连梁超筋而将其设置成双连梁,结构分析时通常把双连梁等效成单连梁再进行计算。根据两者转角刚度、等效刚度应相等的原理,提出转角刚度等效双连梁等效方法并推导出转角刚度等效公式,利用有限元方法验证了其正确性与优越性,为实际工程设计提供了技术支持。
In the design of shear wall structure often encountered beam over tendons and set it as a double beam, the structure analysis is usually double beam is equivalent to a single beam and then calculate. According to the principle that the stiffness of both corners and the equivalent stiffness should be equal, the equivalent method of equivalent stiffness of the double-girder with corner stiffness is proposed and the equivalent formula of the corner stiffness is deduced. The correctness and superiority of the system are verified by the finite element method. Design provides technical support.
