FATIGUE LIFE PREDICTION METHOD AND DEVICE OF CONCRETE BASED ON WEIBULL FUNCTION AND MAXIMUM FATIGUE DEFORMATION

摘要

The present invention discloses a fatigue life prediction method and device of concrete based on Weibull function and maximum fatigue deformation. With the continuous development of modern civil engineering, the fatigue performance of concrete materials has become one of the focuses of concern. The accurate prediction of fatigue life of concrete has become an important issue in the field of engineering construction. The method and device provided in the invention can be used to predict the life of concrete and fatigue deformation evolution law of concrete under the fatigue loads, having the advantages of concise steps, simpleness to use and high accuracy, etc. During the use, it can greatly reduce the computations, and only two fatigue parameters of the number of fatigue load cycles n and the maximum fatigue deformation ε_s of the n^th cycle need to be measured, which simplifies the monitoring equipment. The model can provide an important technical support for engineering design, construction, monitoring and maintenance.
