Modelling of moving load effect on concrete pavements

Abstract

Concrete roads may have different layout arrangement. The structures made of isolated prefabricated slabs are used for the construction of temporary roadways. The paper deals with numerical simulation of moving load effect on isolated slabs on elastic foundation. The computing model of a lorry and computing model of a slab are introduced. The deflections at the middle of the slab and tire forces of vehicle are modeled under various conditions. The influence of speed of vehicle motion and influence of initial conditions are evaluated. The results are presented in time domain in graphical and numerical manner.
