인장을 가하지 않은 강연선 및 프리텐션 강연선 PC보의 휨성능 평가

Abstract

In this study, Flexural behavior of PC Beams parts of tension reinforcied bar transfer within untensioned prestressing strand and prestressing strand. Test parameters in this experimental study were D25 reinforcied bar and Ф 15.2 strand tension use modifications of tension member, and 5 specimens produced. On this tests, all specimens flexural capacites is sufficient. prestress PC beams are good at flexural stiffness and Deflection behavior. Because tension stiffening sffect is relatively high efect on prestress PC beams.
