摘要:波浪腹板H型钢是一类腹板为正弦曲线的型钢构件，具有承载效率高、经济性好等优点，多用于轻型门式刚架结构中。本文介绍了钢结构设计软件STS中波浪腹板H型钢结构设计功能，通过实例分析，比较波浪腹板与平腹板构件用于门式刚架、吊车梁设计中的用钢量，给出波浪腹板的经济性指标。

Abstract: H-shaped steel members with sinusoidal web is a kind of steel components with sinusoidal wave's web. There are many advantages of high efficiency's carrying capacity, good economy, and usually used in light-weight buildings with portal frames. It is introduced the main functions of the program for designing structure with sinusoidal web members in STS software. Through some cases analysis, comparison of steel weight by the design of sinusoidal web and flat web components using in portal frames and crane beam, sinusoidal web's economy index is given in paper.
