(一)适用范围 本文介绍的程序用于计算多层多跨等截面平面刚架各杆件(梁和柱)的端弯矩。为使所计算的刚架规模尽可能大些,本程序只安排计算杆端弯矩,而跨中弯矩、轴向力和切力的计算不包括在内,且要求各杆件的固定端弯矩、作用于结点上的水平力和铅直力以及各杆件的相对抗弯刚度为已知数据输入,故在运行本程序之前必须根据载荷情况预先计算出各杆件的固定端弯矩和作用于结点上的水平力或铅直力,根据各杆件的断面尺寸算出其相对抗弯刚度值。
(I) Scope of application The procedure described in this paper is used to calculate the bending moment at the end of each member (beam and column) of multi-span multi-span plane frame. In order to make the calculated rigid frame size as large as possible, this program only arranges calculation of rod end bending moments, while calculation of mid-span bending moment, axial force and shear force is not included, and the fixed end of each rod is required. The bending moments, the horizontal and vertical forces acting on the joints, and the relative bending stiffnesses of the individual members are known data inputs. Therefore, the fixed end bends of the individual members must be pre-calculated according to the load conditions before running this program. Moments and the horizontal force or vertical force acting on the joint, according to the sectional size of each member to calculate the relative bending stiffness value.
