High-strength steel (HSS) members with welded sections exhibit a notably lower residual compressive stress ratio compared with common mild steel (CMS) members. Despite this difference, current codes often generalize the . Research on the behavior of CFS box sections has reached a relatively advanced stage, with investigations of various steel grades. This observation is evident in the work of Gardner and Yun [5], who collated the results of the material property tests on various CFS grades.More recently, significant attention and efforts have been spent studying the behavior . The tensile test samples were cut from the BS700 steel plate along the hot-roll direction of the steel plate using flame cutting method. Ten thin-walled box section columns (Table 1) were prepared by manual butt welding of the channel-type BS700 high-strength steel.The BS700 material was chosen as the base metal in the component processing stage, during .
In order to evaluate the hysteretic performance of Q690 high-strength steel box-section beam–columns and to assess the rationality of applying Eurocode 3 (EC3) to classify cross-sections of high-strength steel, three non-thin-walled welded box-section beam–columns were designed, and horizontal cyclic loading tests under constant axial force . HSS welded box columns are usually fabricated from quenched and tempered HSS steel plates such as Australian manufactured HSS plates or USA manufactured ASTM A514 HSS plates, and both the plates have nominal yield strength of 690 MPa. Fabrication induces residual stresses in a box section due to strain misfit as the weld material solidifies [1]. The residual stresses distributed in all cross-section satisfies the self-balancing requirement. Comparison of distribution and magnitude of residual stresses between test data and existing models are made. A simplified model is suggested to estimate the residual stresses distribution of steel welded box section made of 800 MPa high strength steel.
