摘要: Abstract This paper presents a test program on screwed connections of thin sheet steels at elevated temperatures using steady state method. The single shear design rules in the current North American, Australian/New Zealand and European specifications for cold-formed steel structures are not applicable to temperature. A total 102 connection specimens were tested temperatures. Three different thicknesses considered this study. failure loads modes obtained from tests. Several observed including bearing, tilting screw shear, net section tension material failure. strengths compared with predicted structures. calculated reduced properties tensile coupon tests It is shown that by generally conservative
