INVESTIGATION ON INFLUENCE OF INFILL WALLS ON HIGHER MODE EFFECT OF SELF-CENTERING PRESTRESSED CONCRETE FRAME STRUCTURES

摘要: 基于《预制混凝土抗震结构体系设计指南》分别构建了具有自复位、摩擦耗能型节点的5层和9层预应力混凝土(SCPC)框架结构模型,并满布填充墙。利用OpenSees软件研究填充墙对自复位预应力混凝土框架结构高阶模态等动力响应的影响。从FEMA P695中选取22条地震动记录并调整至设计基准地震烈度(DBE)和罕遇地震烈度(MCE)水平,分别输入4个有限元模型进行动力分析。研究结果表明:布置填充墙可以有效提高结构刚度和耗能能力,降低结构高阶模态效应和损伤集中效应,以及显著减小结构的层间位移角。此外,布置填充墙后,结构的残余变形虽有一定程度增大,但仍处在可修复范围内。Abstract: The case-study five-story and nine-story self-centering prestressed concrete (SCPC) frames for the PRESSS-Technology Design Example Handbook were selected as analytical model.The friction damper was installed into beam-column connections and infill walls was installed into the SCPC frame structure. The numerical models of the 4 SCPC frame structures were established via the finite element software OpenSees to investigate the influence of infill walls on seismic performance (i.e.higher model effect) of SCPC frames. Furthermore, dynamic analysis under the design basis earthquake (DBE) and the maximum considered earthquake (MCE) actions of 22 suits ground motion records selected from FEMA P695 were carried out on the 4 models accordingly. Comparison of the results showed that the initial stiffness and energy dissipating capacity of structures were improved, the higher model effect and damage concentration effect of SCPC frames were decreased, the inter-story drift ratio was increased. Though the residual deformation was enhanced slightly when the infill walls was installed itno SCPC frame structures, the structure was still repairable.
