高层建筑混凝土剪力墙连梁设计实例分析

Design example analysis of concrete shear wall coupling beam in high-rise building

在高层建筑中,连梁作为剪力墙结构抗震设计中的第一道防线和主要耗能构件,其设计的合理与否直接影响到建筑物抗震性能的好坏。分析剪力墙结构体系的连梁受力和变形机理,结合工程实例分析两种建筑结构类型（剪力墙结构和框架-剪力墙结构）,提出连梁计算模型和超筋问题的处理方法。

In high-rise buildings,the coupling beam is the first seismic defense line and the main energy dissipated components in the seismic design of shear wall structure. The reasonability of the design directly affects the seismic performance of the building. Based on the analysis of the force and deformation mechanism of the coupling beam of the shear wall structural system,combined with the engineering example,two kinds of building structural types（ including shear wall structure and frame-shear wall structure） were analyzed,and the calculation model of coupling beam and the treatment method of the over-reinforced problem were put forward.
