介绍了计算螺纹钢筋强度时横截面积的两种确定方法,即称重法扣公称横截面积法;讨论两种方法的物理本质,并运用实际检测数据进行计算。结果表明,应根据不同的检测目的选择相应的横截面积确定方法。
Two methods for determining the cross-sectional area of the strength of the rebar were introduced, namely the nominal cross-sectional area method of weighing method; the physical nature of the two methods was discussed and the actual testing data was used to calculate the cross-sectional area. The results show that the corresponding cross-sectional area determination method should be selected according to different testing purposes.
