摘要 钢-混凝土组合结构由于兼有钢结构和混凝土结构的优点,近年来得到了迅速发展和广泛应用,目前已成为我国高层建筑领域内应用较多的一种结构形式。虽然在地震区越来越多地采用这种新型的结构,但迄今为止还没有发现对钢-混凝土组合结构的地震易损性进行过研究的文献。因此给出一种基于性能的结构整体地震易损性分析方法,该方法既考虑了结构本身的不确定性,又考虑了地震动输入的不确定性。并定义了结构整体和楼层的四个极限破坏状态,从而提出了基于结构极限破坏状态确定结构抗震性能水平限值的方法。最后采用该方法对两个不同类型的方钢管混凝土框架结构进行基于性能的地震易损性分析,得到结构的易损性曲线,对结构的易损性能进行评估和分析,并比较了两个结构的易损性能。 Steel-concrete composite structures,which possess the advantages of both steel structures and concrete structures,have been quickly developped and widely used. Up to now,it has been a popular structure form for high-rise buildings. Although composite structures have been more and more used in earthquake regions,relevant fragility analysis is not available in the literature. A performance-based fragility analysis method is proposed,with uncertainties due to variability of ground motion characteristics and structures taken into consideration. Four ultimate damage states for entire structure and interstory are defined,and based on which,a method for solving the limit values of the four performance levels is put forward. Seismic fragility analysis is carried out for two different concrete-filled square tubular (CFST) frames,and fragility curves are derived to assess and compare the seismic performances of the two structures.
