美国组合联肢剪力墙抗震设计方法探讨
|
摘要
基于美国加州建筑规范及其引用的相关设计规程和ASCE组合结构委员会的建议,介绍了由钢筋混凝土剪力墙与钢连梁组合而成的组合联肢剪力墙的抗震设计方法。该方法包括:基于中震的水平地震作用计算、合理耦连比的选择、中震及大震水平作用下钢连梁与剪力墙的抗震性能目标、基于先钢连梁屈服后剪力墙屈服的预定屈服机制的构件设计与验算等。据此,建议我国组合联肢剪力墙的第一阶段抗震设计应基于中震水平而不是小震水平。建议方法可供完善我国组合联肢剪力墙结构抗震设计参考。
In this paper,the seismic design method of the hybrid coupled wall structure in the United States is introduced based on the California Building Code and its referencing design standards and the Recommendations for Seismic Design of Hybrid Coupled Walls presented by the ASCE Committee on Composite Construction.The seismic design method described in this paper includes the earthquake action demand calculation,the seismic design performance levels,yielding mechanism design,the component design and check following the prescribed yield mechanism.It is suggested that the first stage seismic design of the hybrid wall be based on the design earthquake level instead of frequent earthquake level.This paper is helpful for developing a rational seismic design method for hybrid coupled walls in China.
