摘要：Strain Hardening Cementitious Composites (SHCC) is a kind of micromechanically designed cement-based composite with ultra high tensile ductility. It is used to fabricate an innovative concrete pipe to improve the structural performance of concrete pipe. The failure processes of reinforced SHCC pipes (RSHCCP) in comparison to these of conventional reinforced cement mortar pipes (RMP) have been investigated under the Three-Edge Bearing Testing (TEBT). Results show that RSHCCP, RMP reveal flexural hardening phenomenon, and RSHCCP's hardening stage is first steep after slow, and has a large deformation, and others is more gently. During cyclic loading, the ring stiffness of pipes were constantly decreases, and the ring stiffness of RSHCCP at hardening stage decreases, is about 20% ~ 90% of the initial ring stiffness.
