- 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．
