型钢混凝土异形柱框架基于位移的抗震设计方法研究
|
摘要
根据型钢混凝土(SRC)异形柱框架的特点,确定出结构的目标位移,并将其多自由度体系转化为等效单自由度体系,推导出相应的等效参数。在此基础上,提出SRC异形柱框架基于位移的抗震设计步骤,并通过算例对结构进行承载力设计,用静力弹塑性分析方法对所设计的SRC异形柱框架进行静力推覆分析,比较结构的侧移形状与初始设计曲线的异同,验证结构是否满足不同性能水平的要求。分析表明,该法操作方便,结果合理,能够控制SRC异形柱框架在不同水准地震作用下的性能,达到基于位移抗震设计的目的。
According to the characteristics of steel reinforced concrete( SRC) frame with specially-shaped columns,the target displacement was determined. The multi-degree-of-freedom system was transformed to an equivalent singledegree-of-freedom system and the corresponding parameters were derived. Furthermore,the displacement-based seismic design procedure of SRC frame with specially-shaped columns was put forward,by which one building was designed. The building was analyzed by using the static elasto-plastic analysis method,checking that the actual drift curve and the initial assumed curve were in agreement or not,and validating that the structure met the requirement of different performance levels or not. It was demonstrated that the method was accurate enough to control the seismic behavior of SRC frame with specially-shaped columns and achieve the aims of displacement-based seismic design.
