摘要：
The excellent mechanical performance of epoxy resins has encouraged their wide-spread application in civil engineering. This paper deals with the prediction of the interfacial shear strength between the steel bar surface and concrete surface of steel rods bonded into concrete. The pull out test is used in order to determine the ultimate force and the shear stress of steel-concrete specimens. The relationship between the ultimate force, the diameter and the length embedded into the concrete are investigated by experimental test. After discussing some theoretical models, a theoretical model is also proposed in this work in order to estimate the shear distribution and the critical shear stress at the instance that the first cracks appear and of the ultimate failure of steel/concrete structure. A comparison between the test and the theoretical results is provided. (C) 2007 Elsevier Ltd. All rights reserved.
