摘要:
Pushover理论广泛应用于结构弹塑性地震分析,也可用于结构极限承载力和失效薄弱点分析.根据钢管混凝土构件统一理论的弯矩一曲率关系,对构件弹塑性状态下截面的弯矩一转角关系进行推导,提出构件M铰和PMM铰特性值的计算方法.根据钢管混凝土简支桁梁结构模型的试验结果,对提出的实用计算方法进行可行性验证.研究结果表明:钢管混凝土构件塑性铰特性值的确定方法是合理的,对钢管混凝土桁梁极限承载力的分析是可信的,为从宏观上掌握大型钢混组合桁架梁桥在弹塑性阶段静、动力性能提供了有效的理论基础和研究手段.
Abstract:
Pushovertheory has not only been widely used in elastic seismic analysis of the stlllcture，but also can accurately describe ultimate bearing capacity andfailure ofweak point of the stnIcture．According to the relationship betweenmoment—curvature of conerete filled steel tubular membersbased on the unified theory，the moment-rotation relationship in elastic-plastic state is deduced，and the calculation method of】Ⅵhinge and PMMhinge properties are put for’ward．Basedon the test results ofsimply—supported girder withconcrete filled steel tubulart11lss，the feasibility of proposed practical calculation method is verified．The comparison results showthat the calculation method to dete瑚ine plastic hinge properties of concrete filled steel tubularmembers is reasonable，and the analysis onthe ultimate bearing capacity of CFSTTrussGirder is credible，which pro— vides an ef耗ctive theoretical basis and research methods to grasp the large steel—concrete composite truss b而dge in elastic—plastic stage static anddynamic pe矗．o珊ance．
