摘要
A new analytical model is proposed to describe the bond strength between a ribbed reinforcement bar and concrete. The model is based on the partly cracked solution of a thick-walled cylinder exposed to radial internal pressure. Instead of considering the minimum crack number in previous solutions, smeared cracking and average stress-strain of concrete in tension are used in radial direction to describe the softening behavior of concrete. The results are compared with Tepfers' classic solutions and other previous solutions.
