浅谈热轧H型钢的工程应用

The application of hot rolled H-shaped steel

阐述了热轧H型钢的截面特性和性能特点，并通过与其他型材的比较，说明热轧H型钢是一种截面面积分配和外形构造更加优化，强重比更加合理的高效型材，认为用H型钢及其派生型材取代其他型材作为结构用钢，可以显示出明显的技术经济合理性。

It illustrate section property and capability charzcteristic of hot rolled H-shaped steel, and after contrast with other shapes, it indicate that hot rolled H-shaped steel is a high efficiency shape with high strength-weight ratio and better optimized distribution of section area and shape constitution. More rationality of technology and economy will effect, if other shapes can be replace with H shapes.
