| 要旨 | The uniaxial tension tests of steel-steel hybrid reinforced ultra-high-performance concrete were carried out to investigate the effects of micro- and macro-fibers on its tensile properties. A dog-bone shaped specimen geometry with a large cross-section size was designed. Although the imperfect test setup introduced bending effects in part of the tests, resulting in an earlier occurrence of first cracking, the tensile strength and strain capacity were found less affected. The test results showed that replacing part of macro-fibers with the micro-fibers can enhance the tensile strength, yet with a cost of ductility. |
