고강도 철근콘크리트 띠철근 기둥의 구속모델 평가

Abstract

The purpose of this research is to evaluate the between test result and previous confinement model such as modified kent-Park, Sheikh-Uzumeri, Saatcioglu-Razvi model, and to provide the information of stress-strain property of high strength confined concrete. Research results indicate that many previous models for confined concrete overestimate or underestimate the ductility of confined concrete. Therefore, reasonable model to predict the behavior of confined concrete is demanded.
