目前对于单层铰接排架已有不少的分析方法。但一般计算公式尚较复杂,有进一步简化的必要。本文所提方法从横梁内力系数的概念出发,结果使横梁内力关系更为明确,公式简单极易掌握,运算非常简便。本方法同样适用于横梁为跨变结构时的情况以及温度应力的分析。 一、符号及说明 横梁及柱的编号见图1,跨度与相应的横梁采用同一编号。单独构件在单位水平力作用下的侧向变形均以δ表示之,单独构件 At present, there are many analytical methods for single-layer articulated racks. However, the general calculation formula is still more complicated and there is a need for further simplification. The method proposed in this paper starts from the concept of the internal force coefficient of the beam. The result is that the internal force of the beam is more clearly defined, the formula is simple and easy to grasp, and the operation is very simple. This method is also applicable to the situation when the crossbeam is a cross-variable structure and the analysis of the temperature stress. I. Symbols and explanations The numbers of beams and columns are shown in Figure 1. The spans are the same as the corresponding beams. The lateral deformation of individual components under the action of the unit horizontal force is denoted by δ, and the individual components
