High-strength structural steel(referred to as high-strength steel)Q460 was selected to optimize the most frequently used H-shaped section bending members and box-shaped section axially loaded members in large boiler steel structure.Results show that,the application of high-strength steel in large power plant boiler steel structure has significant economic benefits.For large plate-bent bending members,the optimal design using high-strength steel Q460 can save 32.5%of the steel quantity.For axially loaded members,the proportion of steel quantity saved decreases with the increase of slenderness ratio and thickness,but the maximum saving ratio can reach 21.7%.
