INTERFACE BEHAVIOUR IN FRP PLATES BONDED TO CONCRETE: EXPERIMENTAL TESTS AND THEORETICAL ANALYSES

摘要

Simplified models for simulating FRP-to-concrete interface behavior are introduced and empirical relationships are utilized for their calibration. Moreover, the results of pull-out tests on FRP-to-concrete joints are presented. They are utilized in calibrating a bilinear shear-stress-to-interface-slip relationship by means of an inverse identification procedure.
