The paper presents a fully Lagrangian mesh-free solver to simulate the dynamic behavior of post-tensioned timber structures. Weakly Compressible Smoothed Particle Hydrodynamics (SPH) is employed to model both the timber and the tendon. An …
This paper presents the dynamic characteristics of the glued-laminated-timber (glulam) floor within China's tallest timber office building and establishes a Finite Element (FE) model. The veracity of the FE model is substantiated through …
Not before the year 2016, the European standard system did allow for classifying the durability of treated wood in addition to natural durability of untreated wood species. After its latest revision, EN 350 (2016) allows a durability …

This work uses the M-theta method on a new proposed specimen called "I-specimen" for the numerical modeling of cracks on some tropical hardwoods in general and in particular on some Cameroonian woods. The finite element analysis of fracture in an …
The fire performance of buildings can be assessed through the thermal and charring characteristics of laminated bamboo lumber (LBL), due to its combustibility properties, which are akin to those of wood. This study employed Thermal Gravimetric …
Virgin cork is a little-known, sustainable and relatively scarce raw material. However, its global output is expected to increase substantially as recent cork oak plantations are stripped for the first time. The work described here aimed to …
