“…Existing studies have reported the development of various methods and techniques to improve the performance of dowel-type timber joints. In order to increase the local bearing capacity of the timber, materials are applied on the surface of the timber member, such as bonded steel plates (Leijten, 1988), punched nail plates (Blaß et al, 2000; Blaß and Schädle, 2011), densified veneer wood (DVW; Leijten, 1991, 1999; Rodd and Leijten, 2003) and glass-fibre-reinforced polymer (GFRP) materials (Chen, 1999; Haller et al, 2006; Haller and Wehsener, 1999; Kasal et al, 2002, 2004a, 2004b). Other strengthening approaches include the insertion of lag screws laterally into the timber members in order to reduce the risk of timber splitting and to carry part of the bolt bearing load (Blaß and Schädle, 2011; Lam et al, 2010).…”

In the event of a seismic attack, the structural integrity of moment-resisting timber frames in the joint region may become compromised and hence the joint may not be able to transfer bending moment around the frame. Often, replacement of a damaged joint is not an option and hence efficient but effective strengthening and repair schemes for such joints are necessary. This article reports the results of 15 tests on 10 metal dowel-type moment-resisting timber connections subjected to monotonic or cyclic loading. Joints are either strengthened or repaired with epoxy, fibre-reinforced polymer composites or steel plates. The ability of the test joints to resist the imposed cyclic loading is presented in the context of hysteresis responses. Recommendations for strengthening and repair interventions are made based on strength, stiffness, ductility, energy dissipation and damping characteristics of the test joints.

“…Bouchair et al (2007) studied the property of plywood as a reinforcing material. The strength and ductility of connections can also be improved by reinforcing the surface of timber members with fiber fabrics, such as textile, glass fiber, and carbon fiber (Haller and Chen, 1999;Haller et al, 1996Haller et al, , 2006Kasal et al, 2004). Steel materials are also suitable as reinforcing materials.…”

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.

“…In the case of timber structures, textiles can offer certain structural benefits especially in the form of reinforced joints, see Figure 3c or Figure 3d and [48][49][50]. Apart from the multitude of advantages that can derive from the use of textiles in timber engineering, however, major restrictions and limits could derive from the different thermal performance of the involved materials.…”

The use of textiles in architecture can cover a wide set of solutions and functions, spanning from buildings, towards geotechnical, aeronautic or automotive fields, etc. Special applications involve textiles in the health care or dressing scenarios. A multitude of other functions can then be found relatively for the use of textiles in building engineering and facades. As far as traditional facades or roofs composed of glass are taken into account, textiles offer a relevant number of potential uses that are specifically focused on energy, acoustic, insulation and even structural goals, in addition to pure architectural objectives. It is known that glass is relatively versatile, but has intrinsic needs and thermo-physical and mechanical features that require dedicated design methods, towards safe design purposes. Glass itself, in the form of constructional material, cannot be directly compared to other consolidated solutions for buildings. The same concept applies to textiles, and to their use to enhance other building components. Besides the key advantages deriving from the use of textiles in glass facades and envelopes—in the form of light, thermal or acoustic insulation, or energy efficiency—special care must be spent for specific structural requirements and performances. In some cases, textiles can in fact offer enhanced resistance to ordinary glass structures. In other conditions, textiles in combination with glass can ensure also enhanced acoustic and thermal performances. A multidisciplinary design approach able to properly fit several objectives should be considered. This paper aims at exploring the actual knowledge on glass textiles, with a focus on available tools and research trends, with careful consideration for structural glass facade applications.
