| 要旨 | This paper describes the results of fatigue tests on three shear ECC beams without web reinforcement. Shear fatigue is found to be more severe than bending fatigue, with fatigue life of approximately one to two orders lower. While the crack surface of control beam tested in static are rough and hairy, those tested in fatigue are all smooth. The damage at cracks around the web region is much more extensive than those nearby loading and support points. At the web region, fibers were completely worn off, while at other regions they bent down and deformed permanently along the crack surfaces. |
