EXPERIMENTAL STUDY ON TENSILE JOINT OF RECTANGULAR SECTION BEAM USING SAWING TIMBER AND LAMINATED TIMBER

Computer-aided Design and Construction of Glued Laminated Timber Structure

The paper presents the computer-aided design and construction of a large glued laminated timber structure in Aosta, Italy. The structure was completely computer modelled with in-house developed software, which considers both torsion and curvature constraints of timber. Further proprietary software was used to develop, on a plane, the shape of each timber layer without torsion and curvature . Th...

Modeling joint production of wildlife and timber

Production of marketed commodities and protection of natural systems often conflict. A focus on only one goal can result in large losses in other goals and may result in inefficient and unsustainable outcomes. In this paper, we develop a method that combines economic and ecological models in a dynamic and spatial analysis to evaluate land use decisions and find cost-effective alternatives for w...

Ambient vibration tests of a cross-laminated timber building

Feasibility of glued laminated timber beams 1 with tropical hardwoods

11 A feasibility study of glulam was carried out in French Guiana using local wood species. The aim 12 was to determine gluing parameters affording satisfactory behaviour to manufactured glulam in 13 a tropical climate. 14 Three abundant wood species, with special properties, were selected for the study and 15 Resorcinol-Phenol-Formaldehyde resin was used for bonding. Three industrial parameter...

Air-coupled ultrasound inspection of glued laminated timber

A novel air-coupled ultrasound (ACU) 120 kHz normal transmission system enabled successful imaging of bonding and saw cut defects in multilayered glulam beams up to 280 mm in height with a signal-to-noise ratio (SNR) of 40 dB. The main wave propagation paths were modeled; quasi-longitudinal and quasi-transverse modes were coupled in each lamella and the sound field was found to be shifted from ...
