Performance of Q690 high-strength steel T-stub under monotonic and cyclic loading
https://orcid.org/0000-0002-3236-607X
Highlights Q690 high-strength steel T-stubs were tested under monotonic and cyclic loading. The T-stub exhibited better ductility under monotonic loading. Increasing the high-strength bolt diameter is beneficial for the T-stub in terms of cyclic performance. A greater bolt spacing, m 1, leads to a higher ductility coefficient and energy dissipation but a lower ultimate load. Using a high material grade results in an improvement of ultimate load and energy dissipation.
Abstract To investigate the performance of a Q690 T-stub, eleven specimens were tested, and a numerical analysis was performed. The results indicate that the EC3 approach can predict the design plastic resistance of the T-stub. The T-stub exhibits better ductility under monotonic loading. Increasing the bolt diameter and material grade is advantageous for the T-stub. A greater bolt spacing m 1 leads to a higher ductility coefficient and energy dissipation. For small flange thicknesses, increasing the flange thickness aids energy dissipation. Further, the effect of the material grade of the bolts becomes more pronounced as the flange thickness increases.
