Abstract: Hot-rolled H-shape steel has multiple advantages such as high dimensional accuracy, good mechanical properties, and no need for welding, making them suitable prefabricated profiles for use in various steel structural components. However, the proportion of hot-rolled H-shaped steel used in domestic civil building steel structures is not high. To understand the current application status and problems of hot-rolled H-shaped steel in civil building steel structures, a survey was conducted on 31 representative design units in China, collecting design information on more than 200 steel structure projects, including basic project information, component sections, design methods, and the application of hot-rolled H-shaped steel. Secondly, the opinions of designers on the application of hot-rolled Hshaped steel were investigated and summarized, and multiple solutions, including optimizing and adjusting the specifications of hot-rolled H-shaped steel, were proposed. Finally, the proportion of various section types of steel structural components and the commonly used dimensions of H shape steel sections were statistically analyzed, laying the foundation for the development of applicable hot-rolled H-shape steel specifications.
