Experimental Investigation on the Local Buckling Behavior of 960 MPa High Strength Steel Welded Section Stub Columns
Although high strength steel has been applied in many buildings and bridges, the application and researches of 960 MPa high strength steel are still quite limited. In order to investigate the local buckling behavior of 960 MPa high strength steel welded section stub columns under axial compression, an experimental program including 8 box and I-section members was conducted. Based on the test results, the local buckling strength and ultimate strength of each specimen were investigated. A finite element model validated through the test results was used to perform a parametric analysis, including 13 box section stub members and 33 I-section stub members with different width-to-thickness ratios. Compared with the corresponding design methods in GB 50017–2003, ANSI/AISC 360–10 and Eurocode 3, it was confirmed that the design methods about the local buckling behavior of 960 MPa high strength steel welded section stub columns under axial compression need to be modified.
