Q460 steel is a typical high strength low-alloy steel and its chemical compositions of Q460 steel specified by GB/T 1591-2008 are listed in Table 1. At each end of the specimen, a 15 mm thickness steel end plate was welded to the specimen and the plate was connected to the test set-up.
At high stress triaxialities, Q460 steel exhibits a typical mechanism of “void nucleation, growth and coalescence”. When stress triaxiality equals to zero, a shear fracture mechanism was observed. At low stress triaxiality values, fracture develops as a combination of shear and void growth modes.
The steel plate used in the Sports Olympic Center this time is Q460, which is a low-alloy high-strength steel. It will deform only when the strength reaches 460 MPa. This strength is stronger than ordinary steel plates and the processing of steel plates is also very difficult. . This is the first time in China that a steel plate of the Q460 specification has been used in a building structure; the thickness of the steel plate
The largest category of this class of steel is flat-rolled products (sheet or strip), usually in the cold-rolled and annealed condition. The carbon content for these high-formability steels is very low, less than 0.10% C, with up to 0.4% Mn. Typical uses are in automobile body panels, tin plate, and wire products.
