“…The tension resistance of bolts can be calculated on the basis of the classic mechanics theory. The transverse compressive resistance of glulam column should be determined according to EN 1993-1-8:2005 (2005) on the basis of the theory proposed by Van der Put (2008) stating that the compressive load perpendicular to grain will spread to the other side within an angle θ , an inference that has also been made by Yang et al (2016).…”

“…The test results showed an effective mode that the steel box section yielded prior to the failure of glued-in rods. Yang et al (2016) implemented three separate steel box sections into the connection and successfully strengthened its shearing force and moment capacity. Generally, connections that combined glued-in rods and steel components were found to sufficiently satisfy the moment resisting and seismic requirements of connections.…”

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.

“…The behavior of glued in-rod joints subjected to bending moments was faced in some papers as in Buchanan and Fairweather [20], where several connections incorporating steel bars are described and tested under cyclic loads, and in Andreolli et al [21], where the investigated joint consists of a wooden element connected to a steel stub by means of an end plate and glued-in steel rods, while Fragiacomo and Batchelar [22] presented a method of evaluating joint strength for a beam to column joint, and Yang et al [23] a component method for calculating the joint performance.…”

Glued-in rod connections for timber beams are increasingly being used, as they offer high strength and stiffness and a better appearance in comparison with traditional mechanical connections. First, a campaign of experimental tests on glued-in threaded steel rod joints subjected to monotonic bending moments was carried out, checking the effect of a confining system for the bars (transversal screws) and the different arrangement of the rods, or varying the mechanical characteristics of the steel of the bars. A negligible effect on joint ductility was observed using transversal screws whereas with a correct design and a proper choice of rod steel grade an important ductile behavior was achieved. The experiments were then extended to cyclic tests so to emphasize the cyclic performance of glued-in rod joints under bending moments. The aim was mainly to understand the joint structural response under cyclic loads, simulating the effects of seismic action. The test results indicate that the joint can initially develop a high dissipative capacity, but after a few cycles, the energy dissipation is considerably reduced by the occurrence of longitudinal splitting in the timber edge of the joining bars leading to lateral instability of the rods.

In this research, the component method implementation for determination of the rotational stiffness of timber-steel connection is shown. Component method is one of the most commonly used methods for determination of the bending moment-rotation relation which later may be used in the practical analysis of the connection. The component method is not widely used for the analysis of the semi-rigid timber connections. There are only several investigations previously done on the component method implementation for the timber connections and most of them are based on only one basic component, i.e. timber compression or glued-in steel rod in tension. This article presents a new investigation of rotational stiffness determination algorithm of the semi-rigid timber-steel connection, which is based on the component method. The component method’s mechanical model of the connection combines all components which have influence on the rotational stiffness of the connection. The analysed timber-steel connection is subjected to pure bending. Stiffness coefficients of the steel part components are determined according to the Eurocode 3: design of steel structures Part 1-8: Design of joints. The timber part components are derived from the full-scale laboratory experiments and finite element modelling results, presented in the previous publications of the authors. The presented rotational stiffness determination results are well in line with the experimental and finite element modelling results, published in the previous publications.
