Abstract

Abstract

In order to investigate the shear bearing capacity of inclined cross screws in timber-concrete composite beams with timber board interlayer, mechanical mechanism of inclined cross screws was studied. Mechanical models for single plastic hinge and two plastic hinges in the shear-compression loaded screw were established. Mechanical models of lateral crushing of timber, single plastic hinge and two plastic hinges in the shear-tension loaded screw were established. The analytical model for predicting shear bearing capacity of inclined cross screw in timber-concrete composite beams with interlayer was proposed, and the calculated results were compared with the experimental results. The results showed that the shear bearing capacity of inclined cross screws could be predicted well by using the calculation method.
