Abstract

In this study, development tests varying with concrete strength, development length, and the rate of fiber mix ratio are carried out to evaluate the development characteristics of high-strength concrete member with 80MPa, and the applicability of estimated standards of development length in KCI 2007. As a result, it can be expected that minimum development length of KCI 2007 is applicable to high-strength concrete member with 80MPa. Although the mixed fiber(NY+PP) to secure fire resistance performance of high-strength concrete is included up to 0.1%, it does not affect the development characteristics.
