摘要:
为进一步推动热轧H型钢产品在民用建筑钢结构中的应用,对热轧H型钢这一工业定型产品的设计原则进行分析总结,建议遵循安全、合理、经济、便捷的原则,并建立起适合我国国情的产品体系。通过对欧洲、美国、日本热轧H型钢产品规格体系分析,结合我国实际国情与建筑业发展趋势,为我国热轧H型钢产品的发展方向提出建议。建议民用建筑用热轧H型钢按构件类型细分型钢产品线,并有针对性地优化现有产品规格、细分级次;开发配套节点、图集,形成标准化成套应用体系;对于受弯构件,应以提高经济性与便捷性为主要研究方向,引导钢结构建筑设计标准化;对于受压和压弯构件,应考虑安全性与合理性,在其适用范围内推广,并通过研发新产品、衍生产品、新结构体系等方式拓展产品适用领域。
Abstract:
To promote the use of hot-rolled H-beam steel products in civil buildings, the design principles of hot-rolled H-beam are analyzed and summarized by the Four Cardinal Principles: safety, reasonability, economy, and convenience. A product system that suits China’s conditions should be established accordingly. According to the analysis of hot-rolled H-beam product specifications systems in Europe, America, and Japan, combined with the actual situation in China and the development of the construction industry, some suggestions are proposed for the development direction of hot-rolled H-beam products in China. It is suggested that the hot-rolled H-section steel for civil construction should be subdivided according to the type of components, and the existing product specifications and subdivisions should be optimized. At the same time, the supporting detailing and the standardized set of application systems should be researched and developed. For beams, improving economy and convenience should be the main research direction to guide the standardization of steel structure design. For compression members, safety and rationality should be highly concerned, which should be used in their appropriate scope. The apposite scope could be extended by inventing new products, derivative products, and new structural systems.
