纵筋配筋率变化时十字形短肢剪力墙弹塑性分析

Analysis on cross shaped short pier shear wall elastic-plastic with the change of longitudinal reinforcement ratio

运用FORTRAN语言编写非线性分析程序,对5个钢筋混凝土十字形短肢剪力墙结构进行单调荷载作用下的弹塑性分析,比较了纵筋配筋率变化时,剪力墙的承载能力、刚度和延性变化情况,分析结果表明,随纵筋配筋率的提高,结构的承载力有所提高,而延性在一定范围有所降低,结构设计中应充分考虑该因素的特殊性,同时考虑承载力和变形能力的变化。

Using the FORTRAN language writer nonlinear analysis program,this paper made elastic-plastic analysis on five reinforced concrete cross shaped short pier shear wall structure under monotonic load,compared with the longitudinal reinforcement ratio changes,the bearing capaci-ty of shear wall,the changes situation of stiffness and ductility,the analysis results showed that,with the increasing of longitudinal reinforcement ratio,the bearing capacity of structures increased,while the ductility decreased in a certain range,in structure design should fully consider the particularity of the factors,simultaneously considering the variation of bearing capacity and deformation capacity.
