Analysis of Joint Load Transfer Performance of Prefabricated Steel-Concrete Hollow Pavement Slab
摘要
Abstract
In order to study the joint load transfer capacity of a prefabricated steel-concrete hollow pavement slab,a finite element model was established with ABAQUS to carry out numerical analysis.The variation laws of the maximum deflection value and joint load transfer coefficient of the pavement slab with and without cavitation were compared to analyze the load transfer capacity.The results show that when cavitation occurs in the slab,the load transfer coefficient of the slab decreases with the increase in the cavitation area,but the load transfer coefficient of the slab does not change significantly when the cavitation depth reaches a certain level.When there is no cavitation in the slab,the maximum deflection value of the slab changes obviously with the increase in load,and when the load is greater than 200 kN,the deflection value changes little.Different hollow forms also have a certain influence on the load transfer coefficient of the slab.The joint load transfer coefficient of the prefabricated steel-concrete hollow pavement slab is greater than 97%in any case,and the maximum deflection values of the loaded slab and the non-loaded slab are not higher than 60(0.01 mm),so the joint can work normally,indicating good joint load transfer capacity and effectively preventing the misalignment problem.关键词
