RESEARCH ON THE SHEAR-TORSION EFFECT OF THE IRREGULAR PLANE STRUCTURE

摘要: 从楼层平衡条件、位移协调条件及材料物理关系三定解条件出发,导出以层位移uk、vk、k为基本未知量的非耦联刚度方程,方法便于初步设计阶段结构布置分析。在归纳大量典型算例的基础上,总结出多高层结构抗剪扭的一些内力分布特征。Abstract: The non-simultaneous stiffness equations, whose fundamental unknown variations are floorcs displacements uk、vkOk are obtained from three conditions of static force equilibriums, displacement compatibility and mechanic relation ofmaterial.The means is conveniently for the analysis of structural layout in the preliminary design phase. Some internal force distribution features of tall building structure are concluded on the basis of a great quantity of typical calculated examples.
