Abstract:
In order to study the impact of various parameters on attenuation law of joint load transfer efficiency of steel fiber reinforced concrete (SFRC) pavement,20 pavement specimens with different dowel bar diameter,length,thickness of concrete slab and content of steel fibers were tested in fatigue experiments.The paper briefly introduced the test arrangement including the raw materials of specimens,the parameters and production of specimens,as well as the loading system.It was shown that the steel fiber added in concrete pavement could effectively improve the load transfer efficiency and reduce the attenuation rate of load transfer coefficient.The attenuation curves of joint load transfer coefficient of SFRC specimens under different factors had similar characteristics,which could be divided into two stages:rapid attenuation and steady decline.However,the curve showd three-stage decay when the content of steel fiber was less than or equal to 0.6％.Although the increase of dowel bar diameter,length and content steel fiber could improve the joint loading performance,the increase range was extremely limited,and the impact of steel fiber content was the largest.The decline rate of load transfer coefficient,which had no relations with dowel bar diameter,length and concrete slab thickness,decreased with the increase of steel fiber content.After the load was applied 100 million times in the experiment conditions,the load transfer coefficient of SFRC specimens was remained above 90％,which showed a good load transfer capacity.The test results could provide a reference for SFRC structural design.
