Behaviour of Normal and Lightweight Aggregate Beams with Shear Cracks

Expressions for aggregate interlock load/displacement relationships and ultimate strengths are deduced from tests of push-off specimens of concretes made with natural gravel and lightweight (expanded clay) aggregates. The results show the importance of crack roughness in the interlock phenomenon. Y.D. Hamadi and P.E. Regan
