DYNAMIC RESPONSE OF A SYSTEM OF 3 RIGID CONCRETE SLABS ON FOUNDATION TO A MOVING LOAD ON THE CONCRETE PAVEMENT USING FINITE ELEMENT ANALYSIS

Abstract

The dynamic response of a concrete pavement system with load transfer dowels under the effects of moving loads is a topic of interest to many scholars. However, to fully understand the nature of the stress-strain state of the concrete slab, load transfer dowels, and the subgrade in the pavement structure, further research is needed. Using numerical methods with the commercial software ABAQUS 2020, this article thoroughly investigates the dynamic behavior of rigid pavement structures under moving loads at a constant speed. The results of this study illustrate the dynamic performance of the pavement structure in terms of vertical displacement on the pavement and vertical displacement along load transfer bars at different wheel trace locations. The research results will provide pavement and airport engineers with valuable insights into the actual working conditions of rigid pavement structures.
