考虑翘曲的一字型配筋砌块砌体剪力墙悬臂梁模型恢复力特性数值模拟研究
|
摘要
基于经过试验验证过的考虑截面翘曲影响的纤维单元模型,该文考虑工程中剪力墙的可能高宽比范围、配筋率、轴压比、砌体抗压强度值等主要因素,用均匀设计法安排一字型配筋砌块砌体剪力墙悬臂梁模型数值模拟试验方案,进行拟静力试验数值模拟分析。结合实际试验结果,回归分析得到该类墙片恢复力特征参数与所考虑因素之间的经验公式,为一字型配筋砌块砌体剪力墙为抗侧力结构的高层结构弹塑性分析奠定了基础。
Based on the research of a fiber element model considering the section warp deformation,this paper uses the uniform design method to arrange the numerical simulation testing scheme of the "一" shaped reinforced concrete block masonry shear wall considering the key influence factors such as the height-width ratio,reinforcement ratio,the axial compression ratio,and the masonry compression strength.Then the quasi static test of numerical simulative models is accomplished.With the actual test results,the features of the restoring force and the empirical equations are presented.The finding of this paper is a base for the elastic-plastic analysis for high rise structures which mainly uses the "一" shaped reinforced concrete block masonry shear wall against the lateral force.
