连续梁板计算方法的分析

The calculation method of continuous board and beam

目前 ,对钢筋混凝土连续梁板在竖向荷载作用下的计算 ,常用的有两种方法 ,即按弹性方法计算和按塑性方法计算。两种方法各有不同的力学依据 ,其计算结果乃至经济效果也有较大差别。更好地了解这两种方法是合理设计连续梁板的关键。并对连续梁板按弹性和塑性两种方法计算作了对比分析 ,同时介绍了两种方法不同的适用范围 ,以求更合理地设计连续梁板。

At present, The calculation method of continuous board and beam under vertical loads has two methods: elastic method and plastic method. Owing to their different mechanical basis, their calculation results and economic effect is greatly different from each other. Understanding the two methods is the key of rational designing continuous board and beam. In this article, the economic analysis is done about two calculation methods of it, and the different applicability of the two methods is introduced in order to design continuous board and beam more reasonably.
