Abstract: Engineered cementitious composite (ECC) is a class of high performance cementitious composites with pseudo strain-hardening behavior and excellent crack control. Substitution of concrete with ECC can avoid the cracking and durability problems associated with brittleness of concrete. In this paper, a steel reinforced ECC beam was tested under four-point bending and compared with conventional steel reinforced concrete beam. According to the test results, steel reinforced ECC beam shows better flexural properties in terms of load carrying capacity, ductility, and damage tolerance compared with steel reinforced concrete beam. Additionally, a simplified constitutive model of ECC material was proposed and applied to simulate the flexural behaviors of beams. The simulation results show that the implemented model is reasonably accurate in simulating steel reinforced ECC flexural members. The crack width of the ECC beam can be limited to considerable low value under service load conditions.
