“…As discussed in previous reports it is important investigating wood from different species as alternatives in preparing Glued Laminated Timber [1]. As an engineered wood product Glued Laminated Timber (Glulam) requires manufacturing precision in all its stages [2][3][4], and only laboratory tests can be used to evaluate finished specimens [5][6][7].…”

Glued laminated timber (glulam) is an engineered product that requires manufacturing precision in all its stages.The finished product can only be tested in laboratory conditions; however, it is necessary to provide the quality control in production to ensure that glulam properties are appropriate to the product specified requirements in accordance with proper codes. This research aimed to evaluate the proposed trials conducted with combinations of Paricá (Schizolobium amazonicum, a tropical wood species coming from a certificate reforestation area), three adhesives (polyurethane, phenol resorcinol formaldehyde, melamine formaldehyde) and two types of treatment (CCA, CCB). The shear strength and delamination test results of all the treated samples showed the good performance of Paricá glulam, which can be used to indoor and outdoor applications.

“…These connections have exhibited good ductility and a quite acceptable slip modulus and load-bearing capacity. Miotto and Dias (2008) investigated connection systems made of rebars of two different diameters glued into timber holes drilled at a 45º angle to the timber grain (Fig. 7i).…”

This review article presents a state-of-the-art survey on timber-concrete composite (TCC) bridges. It starts with a presentation of a sample of relevant TCC bridges, offering a global perspective on the use of this type of bridge. The number of TCC bridges has clearly increased in the past few years, and some of the reasons for this trend are explored. Next, an extensive literature review is presented regarding the most significant technological innovations and recent developments in the application of TCC structures to bridge construction. Firstly, the engineering specificities and the advantages of TCC bridge structural systems are enumerated. Afterwards, the importance of proper mechanical connection for optimal performance of TCC structures is explained, and a thorough description of the connection systems suitable for bridge construction is provided. Some research into the structural behavior of TCC bridges under service conditions is then presented and discussed. Finally, possible areas of future research regarding the development of TCC bridges are suggested.

“…Glued connections [28] and notches cut into the timber joist [24][25][26] are significantly stiffer, yet suffer from lack of ductility. Expanded steel mesh and plates [29][30][31][32][33] have been used largely in softwoods and exhibit high stiffness compared to other connection types, with a good shear force-slip ductility plateau and high strength.…”

The critical T-sections of multi-joist timber concrete composite (TCC) floors must be designed at ultimate for support shear force and midspan moment, both of which are influenced by transverse sharing, but to different extents. Prior experimental work has investigated only support reaction sharing and only up to serviceability loads. The present experimental study builds on that status quo by quantifying also moment sharing, via strain gauge layouts at quarter-span and mid-span, along with reaction sharing via load cells at the supports of a multi-joist TCC specimen, over the entire load range up to failure. Use of steel mesh connectors bonded into hardwood laminated veneer lumber joists, and near geometric resemblance to a real building TCC floor recently built in London, were novel features of the specimen. The results show that midspan moment and reaction sharing both vary nonlinearly with load, but in distinctly different ways from each other (with up to almost 20% difference observed between them), in the progression between the uncracked, cracked and connection ductility regimes. In this approach reliable assessment of moment sharing depends on the quality of the recorded strains. Accordingly, the strain data were shown to be of high quality by converting these data to internal stress resultants that were then found to satisfy longitudinal equilibrium. It is concluded that this strain gauge layout is useful for future work aimed at building a database of transverse sharing of moments in TCCs.
