Abstract: Through summary and analysis, it is proposed that the promotion of hot rolled H-beam in civil buildings should start from the component type and using type to adapt to the design habits of designers.Hot rolled H-beam has many advantages, so the applicative prospect of hot rolled H-beam in field of steel structure is very considerable. However, the current product specifications of hot rolled H-beam dose not capture design requirements for civil buildings. Starting with the characteristics of civil buildings, the requirements of civil buildings for component size and economy were analyzed, the engineers’ common design habits in China was summarized, and the bottleneck of using hot rolled H-beam was sorted out in civil buildings. Through summary and analysis, it is proposed that the promotion of hot rolled H-beam in civil buildings should start from the component type and using type to adapt to the design habits of designers.The grade of hot rolled H-beam products should be subdivided and the section of steel should be optimized according to the design characteristics of civil buildings. For heavy-duty hot rolled H-beam and high-strength hot rolled H-beam, further research should be carried out to clarify the special design method and guide the using in civil buildings.
Keywords:hot rolled H-beam； civil building； steel structure；component type; using type; steel strength; grade subdivided
