浅析剪力墙双连梁设计

对剪力墙进行开洞处理后形成连梁,实现了结构的延性设计。连梁因其自身特点,在设计计算中难度较大。文中根据规范的三项措施提出了合理有效的设计建议,引出"双连梁"这一针对超筋连梁的一种特殊处理手段,对"双连梁"的常用做法和设计模拟进行阐述,并采用SATWE软件对"双连梁"进行两种模拟方式的计算对比。通过国内的试验和汶川大地震验证了双连梁形式剪力墙,具有良好的抗震性能,是值得推广应用的。

Analysis of coupling beam design of shear wall

After the treatment of drilling hole on the shear wall to form coupling beams, the ductility design in the structure was re- alized. Due to its own characteristics, the design of coupling beam is difficult in calculation. According to three measures in the specification, this article proposed the reasonable and effective design proposal, and leaded to a special processing method of＂ doub- le coupling beams ＂. The software named SATWE was adopted to calculate and compare on the two kinds of ＂double beam＂. The shear wall of the forms of double coupling beams, which verified by the test and the Wenchuan earthquake, has a good anti-seis- mic performance and is worthy to apply in practice.
