［摘要］熱軋H型鋼具有很多優勢，在鋼結構中應用前景非?？捎^，但是目前熱軋H型鋼的產品規格一直無法適應民用建筑的設計要求。從民用建筑的特點入手，分析了民用建筑對構件尺寸、結構經濟性的要求，總結了國內常用設計習慣，梳理了熱軋H型鋼在民用建筑中的使用瓶頸。通過總結分析，提出在民用建筑中推廣熱軋H型鋼應從構件類型和使用類型入手，適應設計人員的設計習慣，根據民用建筑設計特點細分熱軋H型鋼產品級次，優化型鋼截面。對于重型熱軋H型鋼和高強熱軋H型鋼還應進行進一步的基礎研究，明確設計方法，引導其在民用建筑中使用。

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
