Summary: | Stress laminated timber (SLT) deck is assembled using timber (lumber or glulam) components placed side by side and stressed together, which has the advantages of easy prefabrication and good cost performance. This work presented an experimental investigation of bending tests performed on SLT slabs. Several parameters, including prestress levels, distance of pre-stressing bars, and the existence of self-tapping screw (STS) reinforcement, were taken into consideration. To reinforce the compressive property of timber perpendicular to the grain, the STSs were placed under the anchor plate of the pre-stressed bars. The experimental results were analyzed and discussed in terms of failure modes, ultimate bearing capacity, ultimate strain, and bending stiffness. It was found that the SLT slab showed satisfactory composite action as well as residual bearing capacity. The pre-stress levels showed an obvious effect on the load bearing capacity and relatively slight effect on the bending stiffness.
