Glued laminated timber (glulam) is widely used as a building material to make up lightweight and large span structures. The fundamental idea behind this substance is to use structural adhesives to join multiple layers of dimensioned wood together, increasing the member's strength and stiffness while also enabling the construction of long-lasting structures with striking aesthetics. At the joints of wood structures, steel plates, aluminum plates, or merely wooden components are frequently used. Steel components that are often used as joints can corrode and also aluminum plates are not resistant to heat. For this reason, the use of non-metallic fasteners is one of the topics that have been emphasized lately sheets onto the timber beam by means of glue or epoxy resins. In this study, columns and beams with cross-section dimensions of 120x120-120x240 were connected to each other with steel fasteners. The connected column-beam joints is reinforced with a glass fiber reinforced polymer and carbon fiber reinforced polymer fabric, 1, 2 and 3 times. Reference column-beam joints and reinforced column-beam joints were subjected to load-displacement test under cyclic loading. After the experimental studies, modeling of column-beam connections was made with the finite element program and load-displacement curves were compared. As a result of the experiment, important structural properties such as maximum load carrying capacity, energy consumption capacity, stiffness value were examined. With the effect of the reinforcement, the load carrying capacities, stiffness and energy consumption capacities of the column-beam connections increased. In addition, it is seen that the bearing capacity of the column-beam connections increases with the increase in the number of windings.

“…Beams made of glued laminated lumber also show great potential for modifying their construction, essentially strengthening them using different non-wood materials. The most common are steel [ 24 , 25 , 26 , 27 ], various types of fiber components or mats [ 28 , 29 , 30 , 31 , 32 ], and concrete [ 33 , 34 , 35 , 36 ]. These modifications result in increased beam stiffness, strength, and fire resistance.…”

The Effect of Periodic Loading of Glued Laminated Beams on Their Static Bending Strength

Engineered wood products (EWP) such as glulam beams are gaining more and more popularity due to several advantages resulting from the wood itself, as well as the constant search for structural materials of natural origin. However, building materials face some requirements regarding their strength. Thus, the study aimed to assess the static bending strength of structural beams produced with the use of pine wood, after the periodic loading of approximately 80 kN for a year. The manufactured beams differed in the type of facing layers, i.e., pine timber with a high modulus of elasticity and plywood. The produced beams, regardless of their structure, are characterized by a similar static bending strength. Moreover, it has been shown that the loading of beams in the range of about 45% of their immediate capacity does not significantly affect their static bending strength and linear modulus of elasticity.

“…The bending tests of TCC beam performed by Yeoh et al (2011a), Du et al (2021b), and Jiang and Crocetti (2019) at room temperature show that shear connectors in TCC beams are essential in providing high composite action between timber beam and concrete slab. The most frequently used shear connectors are steel connectors, such as steel bars (Djoubissie et al 2018), steel dowels (Dias et al 2007), lag screws (Du et al 2019(Du et al , 2020, steel-toothed plates (Yeoh et al 2011b), and self-tapping screws (Kavaliauskas et al 2007;Zhang et al 2020a). The notched connectors (Yeoh et al 2008) and hybrid connectors (Marchi and Pozza 2021) are also used for TCC beams.…”

Shear connectors ensure effective interaction between wood beams and concrete slabs of composite beams, and their properties noticeably affect the fire resistance of timber-concrete composite beams. To investigate the shear stiffness of notched connectors in glued laminated timber (GLT)-concrete composite beams under fire conditions, 16 shear tests were conducted. The effects of fire duration and notch length on shear properties of the connectors for a given spacing were studied. The fire tests indicated that the reduction of the notch length from 200 mm to 150 mm remarkably affected the failure mode of the shear specimens, changing from compression failure of notched wood to shear failure of notched concrete. The increase in fire duration reduced effective width of the notched wood, negatively affected the shear stiffness and shear capacity of the connectors, and the shear stiffness decreased more rapidly. The notch length did not have a substantial effect on the shear stiffness of connectors. Based on the experimental results, an analytical model to estimate the shear stiffness of notched connectors in GLT-concrete beam under fire conditions was established.
