“…The formula requires a parameter that consists of the modulus of rigidity and critical energy release rate, and a method to obtain it was proposed [73]. Other formulae based on analytical and experimental investigations have been proposed to estimate the splitting capacity, and the splitting capacities calculated from these formulae have been compared and discussed [74,75].…”

“…When a bolted joint perpendicular to the grain had an l/d ratio of 4-12.5, e 1 /d ratio of 3.1-25, and e 2 /d ratio of 2.5-12.5, the maximum load increased as the e 1 /d and e 2 /d ratios increased [32][33][34]. When a bolted joint with a small l/d ratio was subjected to a lateral force perpendicular to the grain, a significant tensile stress perpendicular to the grain occurred at the lead hole, and that stress was liable to cause splitting failure from the lead hole to the end of the wood member [35,36]. If the end and edge distances were sufficiently large, brittle failure by the splitting of the wood member could be avoided.…”

The safety and serviceability of timber structures are frequently governed by the performance of joints. Bolted joints are a very commonly used form of joints and are effective from the viewpoint of the load-slip characteristics when subjected to a lateral force. The shear strength of a bolted joint is affected by various factors. Some of the factors affecting the shear strength of a bolted joint are classified into four categories in this paper: the material characteristics, geometrical factors, assembly conditions for the bolted joint, and factors that act during its service. This paper reviews the effects of these factors on the shear strength of a bolted joint. Numerous experimental studies were performed on the shear strength of a bolted joint. The effects of these factors on the shear strength varied according to the kind of shear strength and loading direction to the grain. In addition to the experimental investigations, analytical investigations to estimate the shear strength of a bolted joint are also discussed in this paper. Estimations of the yield strengths of bolted joints have been performed by numerous researchers; and in recent years, there has been an increase in studies to predict the load at failure.

“…Timber connections have been widely used in timber structures mostly as wood trusses. As stated by Xu et al [1], tension and compression in timber is dissymmetric strengths, the behaviour in the joints is not only controlled by the loadcarrying capacity of the individual fastener but it also depends on the form of the joint itself and the interaction of the fasteners. This relation influences the stress distribution in the joint portion.…”

“…[14]. [1] On the other hands, Harding and Fowkes [15] mentioned that the load deformation curve need to be offset a distance 5% of the fasteners diameter from the origin of the load deformation curve which is the intersection of the load deformation curve with a straight line parallel to the initial portion. Recent used of FRP is reported by Nolan and Padilla [16].…”

Generally, the use of timber mainly focuses on simple structures or structures that can take small loads. This paper report on tensile resistance of steel dowelled timber connection wrapped with glass fibre reinforced polymer (GFRP). It involved experimental work in laboratory designed to determine the tensile strength behaviour for half-lap timber connections with steel dowel as the mechanical fasteners. Bintangor species representing strength group 5 and Yellow Meranti species representing strength group 6 were tested in the conditions of with and without the GFRP wrapping. The performances of the connections were observed using the European Yield Model (EYM) as the guideline. The EYM theory is generally used to determine the load carrying capacity of timber-to-timber, panel-to-timber and steel-to-timber connections, reflecting all possible modes of failures. All half-lap connection members were tested at the rate 0.0006 mm/min using the universal testing machine. As a result, it was found that the steel-dowelled half-lap timber connection with GFRP wrapping performed better than the timber connection without the wrapping. The ultimate load of GFRP wrapped connections made of Bintangor and Yellow Meranti species were found increased at 17% and 44% higher compared to the connection without the GFRP wrapping accordingly.

“…An absolute stiffness for normal stress, and the possibility of tangential sliding of two surfaces with the friction coefficient, were used for modelling contact surfaces between steel plates and the wooden element. The coefficient of friction used for the wood-steel contact was taken from available literature [20] and amounts to µ = 0,25. The analysis of the model was conducted using the nonlinear analysis, including the geometrical and material nonlinearity.…”

Ductility analysis of laminated timber beams of small section heightThe purpose of this paper is to analyze and determine the applicability of the models that take into account the ductility of timber elements in bending. Beam elements whose span is many times higher than the height are experimentaly tested. In addition to the tested beam elements, paper presents the mechanical properties of the timber material and the results obtained by finite element method (numerical models). Numerical models are made in the software package Abaqus. Analiza duktilnosti lameliranih drvenih nosača male visineSvrha je rada analizirati odnosno utvrditi primjenjivost modela koji uzimaju u obzir duktilnost drvenih elemenata pri savijanju. Ispitani su i prikazani gredni elementi male visine, dakle elementi kod kojih je raspon višestruko veći od visine. Osim ispitivanja grednih elemenata, dani su rezultati ispitivanja mehaničkih karakteristika osnovnog materijala i prikazana su ispitivanja provedena metodom konačnih elemenata (numerički modeli). Numerički modeli napravljeni su u programskom paketu Abaqus.
