| 要旨 | Testing conditions for obtaining reliable tension softening behavior and fracture energy of the uniaxial tension test have been investigated. First, it is recommended that the applied load should be controlled by the strain of concrete specimen in order to maintain stable fracture during testing. Next, the generation of secondary flexure should be prevented. For this purpose, fixed platens and a force mechanism is required. Not only primary notches but also guide notches are recommended to avoid the occurrences of multiple cracks as well as overlapping cracks. The constant different elongation method can be most reliable for the uniaxial tension test. |
