摘要
根据现行《钢结构设计规范》GB50017-2003公式,可绘出型钢截面拉弯构件承载力N—Mx和N—My相关线,利用这些图线进行截面选择,不但可以减免试算次数,而且还可以进行截面验算;不但计算简单、可靠,而且还可以求出满足可靠性要求、截面面积最小(即最经济)的型钢规格,供工程设计、教学和科研参考。
According to formulae of the （Code for design of steel structures） GB50017 - 2003, N-Mx and N-My relation chart for load-carrying capacity of shaped steel members subject to bending and tension is drawn. Lines in chart are utilized to choose section. Repeated calculation is not needed. The method is not only simple and reliable,but also can meet the stability demand and the area of section is the minimum （the most economical）. It is consulted by engineering design personnd and education research persormd and science research personnel.
