主　　题：Stress laminated timber pre stress bridge deck slabs self tapping screw bending performances 

摘      要：Stress laminated timber(SLT)deck is assembled using timber(umber or glulam)components placed side by side and stressed together,which has the advantages of easy prefabrication and good cost *** work pre-sented an experimental investigation of bending tests per formed on SLT *** parameters,including pre-stress levels,distance of pre-stressing bars,and the existence of self tapping screw(STS)reinforcement,were taken into *** reinforce the compressive property of timber perpendicular to the grain,the STSs were placed under the anchor plate of the pre-stressed *** experimental results were analyzed and discussed in terms of failure modes,ultimate bearing capacity,ultimate strain,and bending *** was found that the SLT slab showed satisfactory composite action as well as resid ual bearing *** pre stress levels showed an obvious effect on the load bearing capacity and relatively slight effect on the bending stiffness.
