简支梁是我们设计和施工中经常遇到的一种最基本、最简单的结构构件,由于它的设计原理简单,受力分析明确,被广泛应用于建筑结构中。也许正是因为它是一种最简单、最基本的结构构件,所以往往被一些设计人员所忽视,认为所有按简支梁计算的构件是不存 Simply supported beam is one of the most basic and simplest structural components often encountered in our design and construction. Due to its simple design principle and clear stress analysis, it is widely used in building structures. Perhaps precisely because it is the simplest and most basic structural component, it is often overlooked by some designers and it is considered that all components calculated by simply supporting beams are not present.
