本文根据原中南工业建筑设计院编“单层厂房排架计算手册”中的一次传播法,在跨间载侧移和跨间侧移常数中,进一步考虑了屋架变形的影响,进行一次往返的传播,就可直接求出锯齿形铰接跨变排架的内力。所用方法,物理概念清楚、计算简便。 Based on the first propagation method in the “Manual for Shelf Calculation of Single-Storey Workshop” edited by the former Zhongnan Institute of Industrial Architectural Design, this paper further considers the impact of roof truss deformation and conducts a round trip For propagation, the internal forces of the zigzag articulated cross-change racks can be calculated directly. The method used has clear physical concepts and is easy to calculate.
