弹性方法和塑性方法的应用比较

Application comparison of elastic and plastic methods

介绍了多跨连续梁结构的两种计算方法,并对弹性方法和塑性方法进行了分析比较,通过对一三跨等跨连续梁进行的列表分析,得出使用塑性方法比弹性方法计算偏于安全的结论,建议应根据不同的情况使用不同的计算方法,以确保计算结果的合理性。

Two calculation methods of multi-span continuous beam are introduced. Comparative analysis is made on elastic and plastic methods. Through list analysis of one continuous beam with equal three spans condusion that calculation results of plastic method is safer than that of elastic method. Author points out that different method should be selected according to various renditions to ensure the rationality of calculation results.
