“…The coefficient of variation values are similar to the values obtained by other authors [23][24][25] . As can be observed, the f c0 , f t0 , f t90 and f v0 values obtained were coherent with the values in Annex E of the Brazilian standard 11 for cedro, cumaru, cupiúba, sucupira and tatajuba.…”

Wood offers a good combination of high strength and low density, but its complete characterization takes a long time. This study aimed to correlate apparent density, chemical component and porosity parameters with the physical and mechanical properties of the wood as an alternative route to reduce the time spent proposing equations to estimate each mechanical property. Ten tropical wood species were characterized in accordance with Brazilian Standards and chemical components were determined by the Klason method, and the porosity using mercury intrusion. Multivariate regression models were applied to the results of each species to find the relationships. Good results were obtained, such as the coefficient of determination and the analysis of variance, which indicated that the equations for 10 out of the 16 properties are significant. Therefore, the apparent density, chemical component and porosity parameters used reduce the time intervals much lower than the time test stipulated by the standard.

“…e consistent properties and fire resistance of PSL are superior to those of raw wood [2]. us, PSL has sufficient strength and rigidity [3] that makes PSL material very well suitable as beams and columns for crossand large-span building structure and for high-rise buildings [2]. In addition, due to the development of the energy-efficient building and green building initiatives, PSL has been becoming an extensively potential prospective structural material for building constructions.…”

Parallel strand lumber (PSL) is an attractive structural wood composite which may have prospective use in building constructions. Conducting nonlinear analysis for the bending of PSL beams is a critical step in the determination of ultimate strength and deflection of them, which is an essential requirement of the building design philosophy based on probability of ultimate state. For the purposes of this article, an inelastic theoretical model regarding the load-carrying capacity of the PSL bending component has been developed. Based on the uniaxial loading tests, the stress-strain behaviors of PSL composite in the grain direction were measured. 4-point bending experiments were also performed in this study to investigate the failure mechanism of the PSL components. The results show that the tensile stress-strain relationship of PSL materials in the grain direction remains linear until breaking, while the compressive stress-strain relationship exhibits nonlinear characteristics once the compressive stress exceeds the proportional limit, which can be expressed by a quadratic polynomial. The failure mode of the PSL beam can be summarized that the fibres in the top of the broken section were buckling and those in the bottom of the section were broken when failure occurred. Significant nonlinear behavior was exhibited based on the load-deflection curves of the PSL beams. To predict the nonlinear bending performance of the PSL beams, a theoretical model that could consider the nonlinear stress-strain relations of PSL and predict the damage modes of the PSL beams was developed. Well agreements can be observed between the results of calculations and experiments.

Wood is an anisotropic structural material with highly variable mechanical properties. The mechanical properties of wood used in timber structures depend on several factors including biological origins, environmental conditions and manufacturing processes. Even the timber members from the same tree are prone to variations in their mechanical properties due to the presence of local defects such as knots and resin pockets. Therefore, the reliability assessment of timber structures needs to take into account the variability of the mechanical properties of timber members. In this study, Random Field Element Method (RFEM) was used to carry out the reliability assessment of a pin connected timber roof truss. The modulus of elasticity were selected as the random field variables for the timber members. Modelling and analysis of the timber truss was conducted using the ANSYS finite element analysis software. The impact of the variation of the mechanical properties of the timber members on the deflections of the truss system used in this study are presented in the conclusions.
