摘要:
对各国已有的壁厚小于2 mm的冷弯薄壁型钢梁受弯性能试验中的86根槽形、40根Z形、6根帽形和6根工字形冷弯薄壁型钢梁的试验资料进行总结。采用中国《冷弯薄壁型钢结构技术规范》(GB 50018—2002)第5.3节中受弯构件的相关规定计算各构件的极限弯矩,将计算结果与试验结果进行比较。结果表明:按中国规范GB 50018—2002规定计算壁厚小于2 mm的冷弯薄壁型钢受弯构件承载力是可行的,试验值均大于规范理论计算值,规范理论计算值偏于安全。
Abstract:
The experiments at home and abroad about bending behaviour of coldformed thinwall steel beams with thickness less than 2 mm were summarized, including eighty-six channel-section specimens, forty Z-section specimens, six hat-section specimens and six I-section specimens. The specimens’ bending capacity was calculated by the provisions of chapter 5.3 in Chinese Current Technical Code of Cold-formed Thin-wall Steel Structures (GB 50018—2002), and the calculation results were compared with the test results. The results show that the process of calculating bearing capacity according to Chinese Code GB 50018—2002 is feasible, and the test results are higher than code calculation values, which means the using of calculation formula set in the norm is reasonable.
