【摘要】 框架—剪力墙结构是应用较为广泛的一种结构体系，但对于大型工业厂房中的框—剪结构，其抗震性能及弹塑性位移研究还很不够深入。本文通过对大型火电厂主厂房纵向框—剪体系进行拟动力模型试验，研究了此类框—剪结构的受力特点、破坏过程及承载力、刚度、变形、延性和耗能性能，并提出了改进结构抗震耗能性能的设计建议。 结合我国现行《建筑抗震设计规范》(GB50011-2001)的要求，采用杆系单元编写了钢筋混凝土框架-剪力墙结构静力弹塑性有限元分析程序。该程序具有与我国规范紧密结合且工程应用方便等特点，可反映框架-剪力墙结构和框架结构在水平地震作用下的破坏全过程与破坏机理，得到其主要受力特征，并可寻找其薄弱部位或薄弱环节，验算其是否能够满足规范的抗震设防要求。程序分析结果与试验结果吻合较好。 应用该程序，本文对某大型火电厂钢筋混凝土结构主厂房纵向框架-剪力墙结构体系的试验模型和原型结构进行了分析比较，得到了这类结构抗震性能的一般规律，提出了一些新的抗震设计理念与构造建议；同时结合研究成果，为我国现行《建筑抗震设计规范》中基于承载力的抗震设计方法提出了一些修订建议。更多还原

【Abstract】 Frame-Shear Wall structure is widely used in Civil engineering, but the study of earthquake resistant behavior and elastic-plastic finite element analysis is very poor for this structure used in large industrial factory building. According to model pseudo dynamic test of the longitudinal frame-shear wall structure of main factory building in a large thermal power plant, the paper investigates loading behavior, failure proceeding, strength, rigidity, deformation, ductility and behavior of dissipating seismic energy, and puts forward suggestions of improving structural anti-seismic behavior.According to the demand of the revision of CSDB, the program for the spectrum-based static elastic-plastic analysis of frame-shear wall structure is written by the finite element method. Not only does this program have the advantage of connecting with CSDB of China , it is convenient for application as well. Using the program, wecangetthewhole failureprocess, the failuremechanism, the internal force characteristics and the weak parts of the frame-shear wall structure when it is suffering the lateral seismic action. Furthermore, Comparing between the results calculated by the program and that of the test indicate that they are analogical.Using the program, both the model structure and the prototype of the longitudinal frame-shear wall structure system of main factory building in a large thermal power plant are analyzed, from which we get the regular pattern of earthquake resistant behaviors of this kind of structure and propose the recommends for b oth s eismic d esign and c onstruction. B esides, t he a uthor p oints o f t he b earing capacity-based seismic design method which is adopted by the current CSDE are pointed and some proposals are given.更多还原
