| 摘 要： | 将楼层整体变形分为剪切变形和弯曲变形,用壁式框架D值法和等效连续体法,对在侧向荷载作用下框筒结构进行简化分析.在考虑翼缘框架对剪切变形影响的前提下,应用壁式框架D值法对整体剪切变形进行分析;在考虑剪力滞效应的前提下,用等效连续体法推导剪力滞系数,分析整体弯曲变形.算例结果表明,简化计算与空间框架计算的结果接近,各柱轴向应变的误差在2%～8%之间,水平位移误差在10%之内.

| Abstract: | Dividing the storey deformation into shear deformation and flexural deformation,by amendatory contra-flexure point method of wall-frame and the equivalent continuum method,a simplified method is carried out to analyze the famed-tube structure subjected to the lateral loads.Considering the effect of shear stiffness of flange frame on shear deformation,the overall shear deformation is analyzed by amendatory contra-flexure point method of wall-frame.Considering the shear lag,the equivalent continuum method is ... |
