초록

This paper assesses the structural performance (force-slip response, slip modulus, and failure modes) of a CLT-concrete composite by conducting fifteen push-out test specimens. In addition, non-linear 3D finite element analysis was also developed to simulate the load-slip behavior of the CLT-concrete specimens under shear load. All 15 test specimens simulating the effect of concrete thickness, connection angle and penetration depth with four different shear connector types were built and tested to evaluate the flexural performance. Experimental results show that the maximum shear capacity for the composite action is obtained when the fixing angle is 90° and the penetration depth of 95mm for SC normal screw was used to achieve ductile failure compared to other shear connectors.
