摘要：
The shear-slip behavior of adhesive/concrete interface was simulated by using the spring element with a damage-type law from the push-out experiment data. A three-dimensional nonlinear finite element model for the adhesive bonded steel-concrete composite beams was proposed. Based on the simulation results, the bonding stress distribution and the debonding process in the adhesive/concrete interface were revealed. Adhesive with less value of elastic modulus makes the shear transformation more evenly, but it may induce a bigger relative slip between the concrete slab and the steel girder, which may impair the carrying capacity of the composite beams. Numerical results reveal that the debonding failure is a typical brittle destroy process with a catastrophic failure of the composite beams and must be paid enough attention during the design process.
