The paper presents an overview of the work, both experimental research and modelling, performed at the Laboratory of Reinforced Concrete, National Technical University of Athens (NTUA) on the behavior of RC interfaces, with focus on interfaces in seismic conditions. The experimental work investigates the effect of all influencing parameters on the behavior of interfaces, and it comprises tests on interfaces crossed by a small number of anchors, on long interfaces crossed by large number of anchors, as well as tests simulating real intervention technique, an existing RC frame filled with a shear wall. The behavior of interfaces is modelled; a global model reproducing the hysteretic behavior of interfaces, as well as an equation adequate for design were developed. Both models account for the two shear transfer mechanisms, as well as of their interaction. The performance of the equation is checked against numerous experimental results and compared with Code equations. The NTUA equation proves to predict more accurately than Code equations the interface capacity for a variety of anchors, embedment lengths, roughness levels, etc.
