摘要：

Calculating the fatigue strength of concrete under the cyclic load of vehicles when des bridges is an issue which is receiving more and more attention from many engin and researchers. Based on this fact, fatigue tests of plain concrete under constant tude and stepping-amplitude cyclic loads were conducted. The mechanism which dam, plain concrete specimens under high frequency fatigue loads was analysed and a non ear accumulative fatigue formula that causes the damage was proposed. A fatigue equa P-S-N that considers the failure probability p' was given. The results of this research good preparation for further studies into high frequency fatigue tests of concrete cylin reinforced with carbon fibre. (C) 2011 Elsevier Ltd. All rights reserved.
