- Abstract:
- The experiments at home and abroad about bending behaviour of coldformed thinwall 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.
