剪力墙结构中双连梁的转角刚度等效方法

Method of the angular stiffness equivalent of double coupling beam in shear wall structures

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。

The problem of over-reinforced coupling beam often encountered in the design of shear wall structures and common solution is setting it to double coupling beam,when carry on the structure analysis usually the double coupling beam is transformed into an equivalent single coupling beam to calculate.Based on the principle of angular stiffness equivalent,double coupling beam angular stiffness equivalent method was put forward and angular equivalent formula was deduced.Its correctness and superiority was validated by finite element method,provides the technical support for practical engineering design.
