Abstract

This study presents the results of ongoing research to investigate the shear-friction behaviour of the interface between high-strength (HS) concrete and lightweight (LW) concrete by conducting tests on 18 push-off specimens with a smooth interface condition. The primary parameters considered are the compressive strength of LW concrete and clamping stress through the shear interface. Together with test data from previous studies, the experimental results indicate that both LW concrete strength and clamping stress have an influence on interface shear capacity. Furthermore, an analytical model for predicting the ultimate resistance of the interface between HS and LW concrete is proposed, and the feasibility of this modified equation verified by the experimental results from related references.
