Abstract:
The flexural ductility of ultra-high-strength concrete members (concrete strength ranging up to 15 ksi or 103.4 MPa) under monotonic as well as reversed cyclic loading is experimentally investigated. The investigation under reversed cyclic loading included an examination of the hysteretic behavior of ultra-high-strength concrete members. The applicability of the equivalent rectangular compression concrete stress block of the ACI Building Code to the prediction of flexural strength of ultra-high-strength concrete members is also investigated.
