Abstract | The design rules on screwed connections of thin sheet steel in the current International specifications
for cold-formed steel structures are only applicable for ambient temperature. Up-to-date, investigation
of screwed connections at elevated temperatures is quite limited. In this study, a total of 24 single shear screwed
connection specimens fabricated from G550 0.42 mm, G500 1.20 mm and G450 1.90 mm thin sheet steels were
conducted by transient state test method. The tests were performed at three different load levels of 25%, 50% and
75% of the failure load at ambient temperature. The critical temperature and the corresponding displacement of
screwed connections were obtained from the transient state test curves. The connection strength deterioration
obtained from the transient state tests was compared with that obtained from steady state tests. The critical temperatures
determined by the transient state test results are slightly higher compared with those deduced from the
steady state test results at similar load levels, and even higher than those from the coupon test results. Different
failure modes, such as bearing, tear out, material failure and several combined failure modes were observed in
the transient tests. It is found that the failure mode of the screwed connections may change as the load level
increases. |
