Tensile Behavior of High Performance Structural Steel T-stub Joints

In this study, experiments were conducted to investigate the tensile behavior of ten T-stub joints made of different types of high performance structural steel including the Reheated, Quenched and Tempered (RQT) grade S690 high strength steel, the Thermal-Mechanical Controlled Processed (TMCP) grade...
