摘要：
Six singly symmetric H-section beams welded by Q460GJ flame-cut steel plates were tested under a concentrated force at middle-span. The tested beams were laterally restrained at middle-span. Compared with the design strength from Code for Design of Steel Structures (GB50017-2003) and the latest version of the steel structure design code (GB50017-201X), it is found that the test results are very close to the strength calculated by GB50017-2003 and the resistance calculated by GB50017-201X is more conservative. © 2016, Engineering Mechanics Press.
