[2014] ANALYTICAL INVESTIGATION ON STRESS TRANSFER IN EPOXY ADHESIVE ANCHOR UNDER TENSION
Keywords:post-installed anchor、 epoxy、FEM analysis、failure mechanisms、combined failure
The authors investigated experimentally and analytically a M12 bolt anchor fixed with epoxy adhesive measuring the length L=100 mm and the drilled hole diameter D=14 mm. A pullout-resistant model was presented and the ratios of supported load were calculated among three constituents in the model at the peak load. Moreover, the stress transfer mechanisms from the bolt surface to the concrete was discussed including the features of the stress transfer through the adhesive-concrete interface. The influence of the bearing plate and the contribution of szz to the failure were also discussed.
