混凝土剪力墙结构静力非线性分析的弯剪模型及实现
Nonlinear static analytical shear-flexure model of RC shear wall structure and its realization
摘要
Abstract
It is necessary for better understanding and grasp on seismic performance of RC (reinforced concrete) shear wall structures to develop its fine nonlinear analysis method. Systemic study on nonlinear static analysis and its realization method are carried out. Beginning with rotating-angle softened-truss model for coupled shear and flexural responses, shear-flexure analytical model of solid wall is presented based on the comparative study on four types of constitutive law of concrete for confined concrete of boundary zone. Good agreements between analytical and experimental load-displacement relation are found, which indicates that the proposed analytical method can well reflect the global mechanical behavior of shear wall well. Study on coupling beam and global perforated wall modeling is implemented, then modeling and nonlinear static analysis method for perforated wall is proposed. By comparing analytical load-displacement curve to experimental results, it is shown that initial stiffness and first turning point agree well and analytical ultimate capacity is close to experimental , which shows that the load-displacement curve can actually exhibit the general load-displacement trend of perforated wall.关键词
