“…[ 18,19 ] The second approach is to use various kinds of components to strengthen the connection at the structural level, which aims at increasing the rotational stiffness of the connection. Some of the existing solutions have applied the hollow variable‐wall‐thickness bolts, [ 20 ] the hollow steel dowels with injected epoxy resin, [ 21 ] steel dowels with expanded tube fasteners, [ 22 ] the plain round rods, [ 12 ] the self‐drilling dowels, [ 14 ] the pre‐stressed tubes, [ 23 ] the knee braces, [ 24 ] the steel angles, [ 25 ] and the friction dampers [ 26 ] to the bolted connections.…”

Currently, there is no "timber moment frame structural system," as the basic glulam beam-to-column connections (usually represented by the bolted connections with slotted-in steel plates) offer limited rotational stiffness such that they are usually treated as pin connections. This paper proposes an innovative type of moment-resisting glulam beam-to-column connection reinforced by long steel rods with screwheads (LSRSs) and long self-tapping screws (STSs). The motivation is to provide a stiff yet resilient beam-to-column connection that could possibly be used for the mid-rise timber moment frame structural system without the need of shear walls or braces. Six specimens with different diameters of LSRSs were designed and experimentally tested to explore their rotational stiffness, moment-resisting capacities, hysteretic moment-rotation responses, and the associated failure modes. Results indicated that the proposed connection could provide not only a satisfying moment resistance, but also the energy dissipation and fast repairability that is related with structural seismic resilience. The design procedures and recommendations for the proposed connection were also provided based on the tested results. The presented experimental study serves as a handy reference for future designs and applications of the proposed connection in practical engineering projects.

“…In addition, Song et al (2016) found that using the carbon fibre-reinforced polymer sheets increased the moment resisting capacity of the reinforced connections by 59% when compared with unreinforced connections. In addition, He et al (2016) proposed a bolt connector with pre-stressed tubes and high-strength bolts. The existence of friction due to the pre-stressed tube was found to increase the initial rotational stiffness of the joint.…”

This article proposes to use the bolted top and seat angles to provide excellent moment resistance and high energy dissipation capacity for glulam beam-to-column connection. Angles are anchored on the glulam beam using the glued-in steel plate technology and connected to the column by anchorage bolts. A theoretical model is presented in this article to evaluate the moment-resistant properties of the connection based on the component method. To validate the accuracy of the theoretical model, several hybrid connections are tested under monotonic and reversed cyclic load. The test results showed that the proposed hybrid connection has a high rotational stiffness and excellent moment resistance. The theoretical results are also consistent with those of the experimental model.

“…At present, there is no standard for bamboo structures. Referring to timber structural standards, which are generally similar to those for bamboo structures, the conventional connection modes can be divided into bolt connections (He et al, 2016), nail connections and truss plate connections (GB 50005-2017(GB 50005- , 2017. Compared with other connection modes, nail connections are the most basic connection for light bamboo and timber structures.…”

Due to the weak withdrawal capacities of conventional nail joints, using double-headed screw joints as reliable connections in bamboo structures is investigated for the first time. A two-step test program is presented in this paper. In the first step, a double shear test is carried out to investigate the influences of the end distance and bamboo grain direction on the performance of double-headed screw joints. The test shows that there are four main failure modes of double-headed screw joints: double-headed screw shear failure, bearing failure of the hole wall, tensile failure of the bamboo cover panel and shear failure of the cover panel end. In the second step of test, the proposed double-headed screw joints are applied to three single-layer single-span bamboo shear walls, and low-cycle reversed loading tests are applied to the walls with double-headed screw spacings of 50 mm, 100 mm and 150 mm. The failure mode, hysteretic behaviour and energy dissipation performance of the shear walls are discussed. Test results show that the two main failure modes of the bamboo shear walls are the tensile failure of the edge of the wall and shear failure of the double-headed screws. Among the different spacings, the bearing capacity and effective stiffness of the wall with a double-headed screw spacing of 50 mm are the largest, the ductility and energy dissipation capacity of the bamboo shear wall with a double-headed screw spacing of 100 mm are the largest, and the bearing capacity and ductility of the bamboo shear wall with a double-headed screw spacing of 150 mm are the worst.
