Abstract
The mechanical properties of high strength structural steel and mild structural steel at elevated temperatures were investigated.The high strength steel BISPLATE 80 (approximately equivalent to ASTM A 514,EN 10137-2 Grade S690Q,and JIS G 3128) and the mild steel XLERPLATE Grade 350 (approximately equivalent to ASTM 573-450) were tested using steady and transient-state test methods.The elastic module and yield strengths were obtained at different strain levels,and the ultimate strength and thermal elongation were evaluated at different temperatures.It is shown that the reduction factors of yield strength and elastic modulus of high strength steel and mild steel are quite similar at the temperature range from 22 ℃ to 540 ℃.The test results were compared with the predictions obtained from the American,Australian,British,and European standards.关键词
