一、前言在工业厂房结构设计中,常常碰到铰接排架的分析,目前计算铰接排架的方法很多,但校核排架计算结果的方法,还未见有文献叙述过。我们在设计的实践中,发现外荷所产生的悬臂梁弯矩与柱底的内部弯矩是平衡的。它们之间的关系,可概括为以下性质①。 I. INTRODUCTION In the structural design of industrial plants, the analysis of articulated and bent frames is often encountered. At present, there are many methods for calculating the articulated and bent frames. However, the methods for checking the calculation results of the frames have not been described in the literature. In our design practice, we found that the cantilever beam moment generated by the external charge is in balance with the internal bending moment at the bottom of the column. The relationship between them can be summarized as follows 1 .
