目前国内常用的计算软件中,空间计算只是针对纯框架体系,不适合发电厂主厂房这种不规则的框排架结构体系.因此在过去的主厂房计算中,通常都是采用平面计算法,即计算一榀简化后的平面框排架。这种方法是近似的、粗略的,其结果也往往保守,造成材料的浪费.随着计算技术的发展,将一个温度段的所有结构元件建立在一个三维模型中来进行空间计算和分析已经成为可能。
At present, the commonly used calculation software in China, the space calculation is only for the pure frame system, and it is not suitable for the irregular frame and frame structure system of the main plant of the power plant. Therefore, in the past calculation of the main building, usually the plane calculation method was used. That is, a simplified plane frame rack is calculated. This method is approximate, rough, and the results are often conservative, resulting in the waste of materials. With the development of computing technology, building all the structural elements of a temperature section in a three-dimensional model for spatial calculation and analysis has become may.
