摘　　要：根据试验研究、有限元分析和理论分析结果,提出按壁式框架计算截面高厚比较大的异形柱框架结构的侧向刚度,并考虑了梁、柱剪切变形的影响,分别给出了理论计算公式和D值法公式。对填充墙异形柱框架的侧向刚度,可采用框架侧向刚度与填充墙侧向刚度相叠加的方法。According to the results of experimental studies, finite element analysis and theoretical analysis, lateral stiffness of frame with special-shaped columns of greater height-width ratio is calculated by using frame with rigid zones,and considering shear deformation of beam and columns. The lateral stiffness of infilled frame with special-shaped columns is calculated by adding the lateral stiffness of frame and infilled wall. The lateral stiffness values calculated by the method are conformed to experimental values for two kinds of the frames.
