论压型金属板截面特性的确定方法

Discussion on determination of section properties of profiled metal sheet

中、日、欧标中关于金属压型板截面几何特性获得方法不同,一般分为计算法和试验法两种。本文结合相关试验数据及计算数据进行对比分析,得出通过承载能力试验实测法获取压型金属板截面惯性矩I和截面抵抗矩W值是正确的方法。

There are different methods for obtaining the geometric properties of profiled metal sheet in the Chinese,Japanese and European standards, which are generally divided into two types: calculation method and test method. In this paper, the relative test data and calculation data are compared and analyzed, and it is concluded that it is the correct method to obtain the section inertia moment I and section resistance moment W of the profiled metal sheet by the actual measurement method of the bearing capacity test.
