摘要
The present invention discloses a fatigue deformation evolution model of concrete based on Weibull function. With the continuous development of modern civil engineering, the fatigue performance of concrete materials has become one of the focuses of concern. The accurate characterization of concrete fatigue performance evolution and prediction of fatigue life of concrete has become an important issue in the field of engineering construction. The model provided by the invention can be used to characterize the concrete deformation evolution law under the compressive, tensile and flexural fatigue loads, having the advantages of diverse applicable forms of loads, simple expression, 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 deformation ε corresponding to the stress of the nth 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.
