【摘要】 综合考虑剪力墙的剪切变形、异形框架柱的轴向变形和连梁刚度对异形柱框—剪结构的抗侧移刚度的影响,利用框—剪结构空间协同分析的连续—离散化方法,以楼层划分单元推导单元的内力、位移关系式,同时采用振型分解反应谱法计算水平地震作用,并考虑层间位移约束条件及刚重比、剪重比等构造要求,建立了中高层钢筋混凝土刚接异形柱框—剪结构的剪力墙抗侧移刚度优化数学模型。工程算例结果表明,本优化模型可行、有效,而且当剪力墙的抗侧移刚度沿结构高度发生变化时,仍可对其进行优化分析。更多还原

【Abstract】 The effects of the shear deformation of shear wall,the axial deformation of special-shaped columns and the stiffness of binding beams on the lateral stiffness of frame-shearwall structure with special-shaped columns are considered.Based on the principle of continuous-discretized analysis of interactive frame-shearwall structures,and formula for innerforces and displacements of elements are developed by dividing floors into element,horizontal earthquake action are calculated by using the response spectrum and a mathematical model is constructed with interstorey drift,the ratio of lateral stiffness to gravity,storey shear to gravity as constrained conditions.An example shows the model was feasible and effective,and it is suitable for frame-shearwall structure with variable lateral rigidity along height.更多还原
