本文系根据俞忽教授集体分配法的原理推广到跨变刚构,文中从基本理論推导得出集体分配力矩系数、集体分配椎力系数、隔点傳递力矩系数和隔点传递推力系数公式。只需要追四个基本公式,对于无論是單层多跨或多层多跨跨变刚构的分析,都一样可以解决。 This article is extended to the cross-varying rigid frame structure according to the principle of Professor Yu Hu’s collective distribution method. In the paper, the formulas of collective distribution moment coefficient, collective distribution vertebral force coefficient, transfer point transmission coefficient, and transfer point transmission coefficient are derived from the basic theory. Only four basic formulas need to be followed. The same analysis can be applied to the analysis of single-layer multi-span or multi-span multi-span rigid structures.
