基于位移的钢—混凝土组合框架结构抗震性能分析
|
摘要
钢—混凝土组合框架结构与钢框架结构相比,有更大的刚度和稳定承载力;与钢筋混凝土框架结构相比承载力强,自重小,延性好,因此钢—混凝土组合框架结构在工程中日益得到广泛应用。关于组合梁和钢管混凝土柱构件层次上的抗震性能研究已趋成熟,但关于钢—混凝土组合框架结构的抗震性能研究还有待完善。本文在已有的组合梁和钢管混凝土柱的研究基础上,对基于位移的钢—混凝土组合框架结构的抗震性能开展研究,对确定钢—混凝土组合框架结构的性能目标,完善抗震规范,为设计人员提供理论依据具有一定的参考价值。
本文在钢管混凝土柱和钢—混凝土组合梁的抗震性能已有研究的基础上,开展了以下几个方面的研究:
1、在静力弹塑性分析中,分析力加载模式和位移加载模式的准确性,提出了合理的位移加载模式,探讨基于位移的组合框架等效单自由度的确立方法,并结合等延性需求谱,提出改进的能力谱方法,利用弹塑性动力时程分析验证该方法的合理性。
2、在已有的钢管混凝土柱和钢—混凝土组合梁理论基础上,探讨在地震作用下钢—混凝土组合框架结构的屈服目标位移和极限目标位移计算方法,并提出相应的计算方法,并利用动力时程分析方法验证该计算方法的正确性。
3、在已有的钢筋混凝土框架结构设计参数的基础上,利用抗弯刚度等效将钢筋混凝土框架结构等效成钢—混凝土组合框架结构,比较在相同抗弯刚度下钢管混凝土柱和钢筋混凝土柱的承载力,并利用动力时程分析方法比较钢筋混凝土框架结构和钢—混凝土组合框架结构的抗震性能。
Comparing with steel frame structure, the steel-concrete composite frame structure has bigger rigidity, stronger stabilization and stronger carrying capacity. Comparing with RC structure, it holds stronger carrying capacity, lighter weigh and better ductility. So the steel-concrete composite frame structure is applied more widely in engineering. The research on the seismic performance of composite beams and steel-concre columns becomes mature, but the research on the seismic performance of the steel-concrete composite frame structure is not perfect. On the base of exsiting reseach base about the steel-concrete columns and the composite beams, the article studys the seismic performance of steel-concre composite frame structure based on displacement, which offers some reference value for ascertaining its performance target, improving seimic criterion and offering theory foundation for designer.
1、In inelastic static analysis, the article analyzes the veracity of force load mode and displacement load mode, puts forward displacement load mode, probes into the establishment of equivalent single degree system, and combining with equivalent ductility demand spectrum, the article advances~- improvement capacity spectrum method, at last the method is validated by dynamic time history analysis.
2、On the existing theory base of steel-concrete columns and steel-concre composite beam, the article discusses the calculating method of the bending targer displacement and the terminal target displacement of steel-concrete composite frame structure under the effect of the earthquake,and puts forward the corresponding calculating method, the method is validated by dynamic time history analysis.
3、Base on the existing design parameters of the RC frame structure, the steel-concrete composite frame structure is equated with the same bending stiffness, the carrying capacitys of the steel-concrete composite frame structure and the RC frame structure are compared, the seismic performance of the both is compared by dynamic time history analysis.
