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 used to deduce the coefficient of shear lag and to analyze overall flexural deformation.The calculation results by simplified method is close to the results by spatial frame,the error of axial strains of columns is 2%~8%,the error of horizontal displacements is less than 10%.
