Abstract

Abstract

It was presented an experimental investigation on structural behaviour of welded H-sections fabricated from high-strength steel sheet with a nominal yield stress of 460 MPa.A total of six tests were performed on high-strength welded H-sections subjected to axial compression force.The comparison of the test results with the design strengths calculated using the Chinese Code for steel structures showed that the long column design strengths predicted using the curve c specified in the Chinese Code were conservative,while the reliability of the design strengths predicted using the curve b needed to be assessed using reliability analysis.Furthermore,a total of four cyclic loading tests were conducted to study the hysteretic behavior of high-strength welded H-section beam-columns.The test result showed that the Q460 steel welded H-section beam-columns possed good ductility and a certain degree of energy dissipation capacities.
