Abstract

Laminated Veneer Lumber (LVL) is one of the engineered wood products consisting of wood veneers that are glued and pressed together. In this study, the behavior of LVL Sengon slender beam is numerically investigated by means of nonlinear finite element analysis (FEA), where only half of the experimental beam was modeled due to symmetry of the load configuration. The LVL Sengon wood material used Hill failure criterion with isotropic hardening rules, and its mechanical properties in both tension and compression are modelled according to its mechanical properties in tension obtained from the clear specimen test. The contact analysis is defined for each contacting and contacted elements. The FEA results well agreed with the experimental results in term of the load-deflection curve and failure mode of the beam. It is found that the lateral support has no effect on the stiffness of the beam. The beam stiffness and ultimate load increase by the increase of beam height-to-width ratio (?/?).

Abstract

The utilisation of Rubberwood was an effort to provide an alternative to low-cost housing in Indonesia. This study investigated the use of Rubberwood Finger-Jointed Laminated Board (FJLB) under compression loading parallel to the grain. The investigation included laboratory experiments and numerical analysis. The experiments were conducted using two specimens of FJLB members, each with a length of 2000 mm and a cross-sectional dimension of 100 mm × 100 mm². Finite element analysis (FEA) was employed to predict the axial capacity, considering non-linearity, contact boundary conditions, and buckling analysis of the material. The study found an average axial capacity of 150.9 kN for the two specimens, which was 3.2% higher than the FEA and 5.4% higher compared to the Euler formula. Laboratory measurements revealed that initially, the stress distribution in the cross-section was uniform, then suddenly changed to a combination of tension and compression during the final loading stage.
