［摘要］對壁厚為1mm的冷彎薄壁卷邊槽鋼的受彎承載力性能進行了試驗研究。共完成了兩種截面、三種不同跨度的13根簡支梁試件的試驗。將試件的試驗承載力與采用我國現(xiàn)行標準《冷彎薄壁型鋼結(jié)構(gòu)技術(shù)規(guī)范》(GB50018—2002)規(guī)定計算結(jié)果作了比較。對比結(jié)果表明，按我國規(guī)范GB50018—2002規(guī)定計算厚度小于2mm冷彎薄壁型鋼受彎構(gòu)件承載力是可行的，試驗結(jié)果均高于規(guī)范理論計算值，規(guī)范計算值偏于安全。

Abstract:The experimental study focuses on the flexural bearing capacity of cold-formed lipped channel members with thickness is 1mm. A total of 13 simply supported beam members with two sections and three different spans were tested. The test bearing capacity of the members has been compared with the calculated results based on the provisions of Chinese current code, “Technical code of cold-formed thin-walled steel structures” GB50018—2002. The results show that the process of calculating bearing capacity according to Chinese code GB50018—2002 is feasible, and the test results are higher than calculated values, which means the using of calculation formula set in the norm is reasonable.
Keywords:cold-formed steel; lipped channel; flexural members; experimental study
