摘　　要：矩形截面抛物线楔形梁作为一种变截面杆件在平面框架结构中经常使用。本文通过求矩形截面抛物线楔形梁的单元柔度系数、刚度系数,提出了平面框架结构中矩形截面抛物线楔形梁的单元刚度矩阵。As a variable cross-section member, parabolic wedge shaped beam of rectangular section is used frequently in plane frame structure. By solving flexibility and stiffness factor, this paper presents element stiffness matrix of parabolic wedge-shaped beam of rectangular section in plane frame structure.

关 键 词：柔度系数 刚度系数 刚度矩阵
