一、现行桥规计算方法存在的问题现行桥规中关于砖石结构受压构件的计算方法,由于考虑了材料的塑性,因而它比旧桥规前进了一步。但它仍然存在方法复杂、公式繁多、彼此矛盾、承载力偏低、边界条件不符等问题。为了便于说明这些问题,先将现行桥规的方法介绍如下,然后再来分析其存在的问题和解决途径。
First, the existing bridge gauge calculation method Existing problems The existing bridge gauge on the masonry structure of the compression member calculation method, due to consider the plasticity of the material, so it is a step ahead of the old bridge gauge. However, there are still some problems such as complicated methods, numerous formulas, contradictions with each other, low carrying capacity and inconsistent boundary conditions. In order to explain these problems, the methods of the current bridge gauge are introduced as follows, and then the existing problems and solutions are analyzed.
