Analytical and numerical investigation of adhesively bonded perfobond shear connectors for timber-concrete composite floors

Appavuravther, Elif LU ; Vandoren, Bram and Henriques, Jose (2024) In Structures 70.
Abstract
In timber-concrete composites (TCC), more researchers are trying to find the “ultimate” shear connector, which combines multiple advantages. Bonded steel plates are one of the possible solutions. This paper provides an analytical and a numerical approach, calibrated with previously conducted experiments, to predict the load carrying capacity, and corresponding governing failure mode, of perfobond shear connections in TCC beams. The connection’s mechanical model includes all possible failure modes which can limit the connection strength based on load transfer mechanism. Accordingly, failure modes are first identified and their resistance assessed using strength models available in the literature. Subsequently, the assembly of these... (More)
In timber-concrete composites (TCC), more researchers are trying to find the “ultimate” shear connector, which combines multiple advantages. Bonded steel plates are one of the possible solutions. This paper provides an analytical and a numerical approach, calibrated with previously conducted experiments, to predict the load carrying capacity, and corresponding governing failure mode, of perfobond shear connections in TCC beams. The connection’s mechanical model includes all possible failure modes which can limit the connection strength based on load transfer mechanism. Accordingly, failure modes are first identified and their resistance assessed using strength models available in the literature. Subsequently, the assembly of these determines the connection resistance and the governing failure mode. Then, a three dimensional finite element model is created in Abaqus to deepen the connection’s mechanical behaviour and further validate the proposed analytical approach. Finally, a parametric study is conducted with the aim of achieving a ductile behaviour of the connections. The accuracy of the proposed analytical model is assessed with the parametric study. (Less)
