弹性支座较固定支座更接近于工程实际,但由于计算工作量较大,目前尚无较好的计算方法.本文提出用位移法计算弹性转动支座上的刚架,只要引进弹性转动支座的形常数、载常数的概念,就与普通刚架分析完全相同,从而大大地简化了此类结构的计算. The elastic bearing is closer to the engineering than the fixed bearing. However, due to the large calculation workload, there is no good calculation method. This paper proposes to use the displacement method to calculate the rigid frame on the elastic rotating bearing, so long as the elastic rotating support is introduced. The concept of the shape constant and the load constant of the seat is exactly the same as the ordinary rigid frame analysis, which greatly simplifies the calculation of such structures.
