Abstract:The design points of steel beam using moment modulation method were stipulated in detail by Steel structuredesign standard (GB 50017—2017), but the practical application of moment modulation method is still few. According tothe Design method for steel structures and steel-concrete combined structures, the application significance, theoreticalbackground, applicable conditions and construction requirements of the moment modulation method design in steelstructures were introduced in detail. It is hoped that the introduction of related content can promote the application ofmoment modulation method in steel structure design.

Keywords:steel structure; moment modulation method; construction requirements
