平面框架结构中矩形截面抛物线加腋梁刚度计算

摘要

以某端部抛物线加腋的矩形梁为例，计算了矩形截面抛物线加腋梁的单元柔度系数、刚度系数，提出了平面框架结构中矩形截面抛物线加腋梁的单元刚度矩阵，提高了单元刚度的计算精度，从而满足结构设计要求。%Taking the rectangular beam of an end of parabola haunched as an example,this paper calculated the element flexibility coefficient, stiffness coefficient of rectangular section parabola haunched beam,put forward the element stiffness matrix of rectangular section parabola haunched beam in plane frame structure,improved the calculation precision of element stiffness,so as to meet the design requirements.
