基于损伤的构件抗震性能评价方法研究与软件开发

Study and software development of damage-based seismic performance evaluation method for components

根据《高层建筑混凝土结构技术规程》(JGJ 3—2010)中的结构抗震性能设计,结合《混凝土结构设计规范》(GB 50010—2010)中的混凝土本构关系,针对多高层混凝土结构,提出基于损伤的钢筋混凝土梁柱构件、剪力墙构件和钢管混凝土构件的抗震性能评价方法。通过ABAQUS软件的二次开发功能,实现应力-应变层次上的抗震性能评价标准的应用,并通过工程实例验证评价标准的适用性。

According to the structural seismic performance design of Technical specification for concrete structures of tall building （JGJ 3--2010） and combining with the concrete constitutive model in Code for design of concrete structures （GB 50010--2010） , a damage-based seismic performance evaluation method was presented for reinforced concrete beam-column components, shear wall components and concrete filled steel tubular components in multilayer and high-rise concrete structures. With the secondary development function of ABAQUS software, seismic performance evaluation standard in stress- strain level was applied to structures. An engineering structure was used to verify the applicability of evaluation standard.
