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.
