Ambient vibration tests of a cross-laminated timber building

Structural Tests of Concrete Composite - Cross - Laminated Timber Floors Final Report

Experimental tests of a composite concrete-cross-laminated timber (CLT) floor system were conducted. The floor system was constructed with 5-ply CLT panels (6.75 in. thick) made composite with a 2.25 in. thick reinforced concrete topping slab. Four series of tests were performed using different specimen configurations and laboratory testing methods. Tests included: (1) Comparative one-way bendi...

Bending Properties of Cross Laminated Timber (CLT) with a 45° Alternating Layer Configuration

Bending tests were conducted with cross laminated timber (CLT) panels made using an alternating layer arrangement. Boards of Norway spruce were used to manufacture five-layer panels on an industrial CLT production line. In total, 20 samples were tested, consisting of two CLT configurations with 10 samples of each type: transverse layers at 45° and the conventional 90° arrangement. Sample dimens...

Cross Laminated Timber Construction for Resisting Lateral Loads on Six Level Buildings

The author’s intention is to contribute to the general discussion on timber multi-level commercial buildings. Interest in this topic is expected due to the environmental advantages of timber construction when compared to concrete and steel. This paper looks into three timber based systems for resisting lateral loads for buildings to six storeys, that will ensure relatively ‘open’ floor spaces. ...

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...
