本刊1980年第6期发表的“刚架强迫振动计算”一文(以下简称[1]文),是手算此类问题的较简捷之法,曾被实际工作者所采用。本文是应一些设计工作者的需要在[1]文的基础上作了进一步改进的结果。本文用了不均衡力(力矩,侧力)与形变分向(按不同方向)传播之方法,使所需之动力形变传播系数,动力修正弹性常数的计算工作量均可减少一半。文内导有横梁两端动力水平力与两端动力变位之关系式以及横梁及柱端之动力修正固定端力矩,动力修正固定端水平力等公式。
The article “Calculation of Forced Vibration of Rigid Frames” (hereinafter abbreviated as [1]) published in the 6th issue of 1980 is a simpler method of calculating such problems by hand and was used by actual workers. This article is based on the needs of some design workers in the [1] article based on further improvements. In this paper, the methods of unbalanced forces (torque, lateral forces) and deformation (in different directions) are used to make the necessary calculations of the power deformation propagation coefficient and the dynamic correction elastic constant. The article describes the relationship between the horizontal force at both ends of the beam and the dynamic displacement at both ends of the beam as well as the beam and the column end of the power to modify the fixed end of the torque, dynamic correction of the fixed end of the horizontal force and other formulas.
