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. ...

Stabilizing stick-slip friction.

Even the most regular stick-slip frictional sliding is always stochastic, with irregularity in both the intervals between slip events and the sizes of the associated stress drops. Applying small-amplitude oscillations to the shear force, we show, experimentally and theoretically, that the stick-slip periods synchronize. We further show that this phase locking is related to the inhibition of slo...

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...
