Crack Width Evaluation of RC Members Reinforced with Braided AFRP Bars (Part 1: Pullout and Tensile Bond Test of AFRP Bars)

摘要

A pullout bond test is carried out to obtain the bond constitutivelaw. From the test results it can be found that surface of AFRPbars determines the characteristic of bond constitutive law.Tensile bond test has also been conducted. It is remarkably thatbond phenomenon between concrete and reinforcementdetermines the characteristic of crack patterns.
