Fundamentals of bridge dynamics under moving loads
There are mainly two methods for dealing with the structural analysis of bridge structures under moving loads. On the one hand, an analytical solution is provided for beam systems with uniformly distributed mass and elasticity (FRÝBA, 1972; CLOUGH et al., 1995; CHOPRA, 2014; PETERSEN et al., 2017). On the other hand, an efficient solution can be achieved using the FEM (CLOUGH et al., 1995; PETERSEN et al., 2017; WERKLE, 2021). The latter idealizes the system by a set of elements interconnected at nodal points, which are used to form a coupled system of differential equations of motion (BATHE, 2014; WERKLE, 2021). This chapter briefly introduces some relevant aspects of structural dynamics and presents typical methods of dynamic analysis of bridge structures under action of moving loads.
