【摘要】 本文以某大型火电厂主厂房纵向框架一剪力墙结构为原型，通过模型试验和有限元分析，研究了纵向带边框柱中高剪力墙结构的抗震性能问题，主要内容有： 选用1／15缩尺比把某大型火电厂主厂房纵向带边框柱剪力墙原型结构模拟为一个模型结构，并进行了伪静力试验，研究了这类纵向带边框柱中高剪力墙结构的开裂与破坏过程、骨架曲线、刚度退化、延性性能等问题，试验滞回曲线饱满，消能能力强，说明此类中高剪力墙的抗震性能较好。试验承载力验证了《高层规程》提供的公式安全储备较小，宜进行加强。而后提出了用变系数的方法，计算结构在不同受力阶段位移的简化实用公式。 首先选用分层组合式有限元方法利用数值方法分析剪力墙结构的承载力、位移、延性性能、破坏形态、塑性铰等问题。所得结果同试验吻合较好。其次采用ANSYS中的结构计算模块，用SOLID65单元分析了剪力墙模型结构，得到了承载力、变形、裂缝的发生发展以及结构的应变和破坏形态等结果。再次采用宏观有限元方法分析了模型结构的承载力、位移、破坏形式等问题。对比试验与计算结果，表明三种有限元方法分析中高剪力墙精度均较好，可以在中高剪力墙结构分析中应用。 研究结果表明，纵向带边框柱中高剪力墙结构的抗震性能较好，能够在大型火电厂中应用。此外，文中还提出了一些这类结构抗震设计与构造建议。更多还原

【Abstract】 The seismic behavior of longitudinal middling-high R.C shear wall with frame column is discussed through model experimentations and finite element methods in this paper, after taking frame-shear wall structure of a main factory building of the large capacity power plant as experimentative prototype. The major work as follow:In order to appliance pseudo static test, the longitudinal middling-high R.C shear wall with frame column in the large capacity power plant’s main factory building has been simulated to a model structure with 1/15 reduced-scale. The contents of study are process of cracking, course of damage, skeleton curve, rigidity degradation, ductility characteristic etc. That the seismic behavior of this kind of middling-high R.C shear wall is excellent has been proved by chubby hysteretic curve and fine capacity of energy dissipation. The experimentative load-carrying capacity attest that safety store is small, so it should strengthen structure capacity. Finally, the simple and applicable formula is presented in order to calculate the shear wall’s displacement indifference phases.Firstly, the shear wall’s load-carrying capacity, displacement, properties of ductility, shape of damage, distribution of plastic hinge are analyzed through delaminating combination finite element method with numerical value method. The result is accord with the experimentative result. Secondly, model structure’s load-carrying capacity, deformation, crack’s generation and development, structural strain and shape of damage are analyzed with SOLID65 element in software’s structural calculation module. Finally it discussed the model structure’s load-carrying capacity, deformation, shape of damage etc. through macro finite element analysis method. The three finite element analysis methods can precisively analyze middling-high R.C shear wall structure and apply in this kind of structural analysis.The study result indicate that the seismic behavior longitudinal middling-high R.C shear wall with frame column is good, so it can be apply in main factory building of the large capacity power plant. Moreover some advices for this kind middling-high shear wall’s design and constitution are presented.更多还原
