型钢混凝土框架结构量化性能指标的理论分析
|
摘要
结构的层间变形由框架梁、柱和节点共同引起,通过分析三种构件产生的层间转角大小,得到钢筋混凝土框架结构的层间屈服位移角计算公式,对比表明,公式计算结果和试验数据吻合较好。采用相同的假设和方法,分析提出型钢混凝土(SRC)框架结构的层间屈服位移角表达公式,并按照各个性能水平极限状态之间的关系,提出具有一定概率保证的SRC框架结构的量化性能指标,为此种结构体系基于性能的抗震设计提供理论基础。
The interstory drift of frame structures is caused by beams,columns and joints. The calculation formula of yield story drift angle for reinfoced concrete frame structures is obtained by adding above three kind of deformation,and the compa rative analysis show that theoretical results have good consistency with experim ental data.The expression formula of yield story drift angle for steel reinfoce d concrete(SRC) frame structures are analyzed by using the same hypothesis and m ethods,and quantified performance index for SRC frames having a certain guarant ee value are proposed according to relationship of various seismic performance l evels.The conclusion obtained provide basic information for performance-based sisimic design of SRC frame structures.
