Abstract

This article presents an experimental study on the moment-resisting capacity and stiffness of the proposed pre-stressed tube bolted connection. High-strength bolts with tubes were used as fasteners in such connections. A series of monotonic and reversed cyclic loading tests were conducted with T-shaped glulam beam-to-column connections. The strength, stiffness, ductility, and energy dissipation property of the pre-stressed tube bolted connections were obtained and compared with traditional bolted connections. Meanwhile, the effect of self-tapping screw reinforcement on increasing the structural performance of the pre-stressed tube bolted connection was also investigated. The results showed that the initial rotational stiffness of pre-stressed tube bolted connection improved significantly as a result of the friction between steel tubes and steel plate together with the tight-fitting of tubes and timber holes. The ultimate moment-resisting capacity and ductility of the pre-stressed tube bolted connection were also increased when self-tapping screws were applied.
