摘要: Abstract Fracture mechanics based flexural model for layered engineered cementitious composite (ECC)-concrete beam is proposed. With the model, behavior of simulated. The results show that strength improvement depends on concrete and ECC, as well thickness ECC. As ECC reaches a critical value, such 30% height, member ductility found to very rapid increase. performance ECC-concrete beams was investigated also experimentally. Good agreement between test found.
