“…The main experimental results-namely, elastic stiffness (k e ) and peak load (P peak )-are summarized in Table 3. According to [19], the test results did not have good agreement with the theoretical calculations. In experimental tests, the rotation centers of the connections varied (due to the members' compression and wood splitting) during the loading process, while in the mechanical model, the connections were simulated by nonlinear spring elements with fixed rotation centers.…”

“…Ref. [19] developed a structural analysis in a semi-rigid timber portal frame and studied the moment resistance of its connections by experimental tests (monotonic and cyclic) performed on three full-scale timber portal frames and five bolted timber connections. All of the frame specimens had a span of 4110 mm and a height of 2740 mm (span-depth ratio of 1.5).…”

Ductile Moment-Resisting Timber Connections: A Review

et al. 2022

In the last two decades, high-rise timber buildings have been built using the glulam truss system, even with limited openings. Moment-resisting timber frames (MRTF) with semi-rigid beam-to-column connections can be an architecture-friendly way to provide a load-carrying system to vertical and horizontal loads for timber buildings. In these structures, connections of adequate ductility are crucial to ensure robustness and energy dissipation. This paper presents a review of the main types of timber beam–column moment connections with improved ductility and proposes to carry out a ductility assessment of these connections based on the most relevant ductility factors. Joints have a significant influence on the global performance of MRTF, and the application of ductile connections have improved the mechanical parameters of the timber frame. The reinforced bolted slotted-in steel plate and glued-in rods connections have similar mechanical performance, with high rotation capacity and good ultimate moment, but exhibited different failure modes under cyclic loading. The connections were classified within ductility classes. In general, the glued-in steel rods presented better results because of the high influence of steel profiles in the connection yielding. Despite the excellent mechanical behavior, the reinforced bolted slotted-in steel plate connections presented medium ductility values.

“…Numerous studies on bolted timber joints have been performed on their load-slip characteristics subjected to a lateral force, which are governed by the embedment stress and deformation characteristics of timber, the bending stress and deformation characteristics of the bolt, and the geometric properties and types of joints (DeJong, 1977;Echavarrı´a et al, 2007;Santos et al, 2010;Sawata and Kei, 2015;Tlustochowicz et al, 2011). Numerical studies were also carried out to calibrate the experimental results and provide better modeling to the embedment behavior and the bolted connections (Liu and Xiong, 2018;Schoenmakers et al, 2010;Xu et al, 2013;Zhou and Guan, 2006).…”

This paper reports tensile and compressive test results of bolted glubam (glued laminated bamboo) connections. The tensile tests were carried out with two types of specimens designed for tensile loadings in the longitudinal and transverse directions in relevance to the orientations of the bidirectional bamboo strips (fibers). In each direction, the specimens were further divided into nine groups according to different combination conditions of end and edge spacings. Compressive tests were executed for three groups of bolted glubam connections, with varying thickness of the main board and bolting conditions. The tensile experiments show that the failure of the specimens is strongly influenced by the loading directions. Recommended end distance and side distance are provided, whereas the load carrying capacity is analyzed. Based on the compressive testing results, failure modes and load displacement relationships are analyzed, in which the yield bearing capacity is shown to be close to that given by the equations in existing design specifications for timber structure.

“…Consequently, the above studies only focused on the bearing capacity of the joint. However, in practice, the bolt group joints show semirigidness and undergo a certain bending moment and may crack as a result, which influences the performance of the structure [10,11]. For the determination of the semirigidness of a joint, it is necessary to probe the stiffness of a single-bolt joint and the process-wide forcedisplacement relations [12,13].…”

To study the force–displacement relations of bolted timber joints with slotted-in steel plates, we performed a monotonic loading test parallel to the grain on 24 specimens. The influences of the bolt diameter, timber thickness, and their ratio were considered. As shown by the test results, the joints had a high deformation capacity and experienced a linear stage, a stiffness degradation stage, a yield plateau stage, and a failure stage during loading. Based on the curve fitting and parameter identification, the force–displacement relations of the joints were summarized in a mechanical model with two parameters, i.e., the bearing capacity and the elastic stiffness. Based on theoretical analysis, we proposed a theoretical calculation formula for the bearing capacity and elastic stiffness of the joints. Finally, we calculated the force–displacement relation curves of bolted timber joints with slotted-in steel plates using the mechanical model and the theoretical formula. The calculated curves fitted well with the experimental curves.
