Abstract :In this  study, the two first probabilistic characteristics of a two lane slab-type-bridge response due to traffic flow is investigated. A two lane slab-type-bridge is modelled by a Simply Supported insert ignore into journalissuearticles values(SS); thin rectangular plate with two separate rectilinear paths. The modelling of the traffic flow is based on the assumption that two opposite series of vehicles of random weights arrive at the bridge at random times that constitute the Poisson stochastic process and with the stochastic velocities. The expected value and the standard deviation of the bridge deflection are obtained. We demonstrate that the bridge safety strongly depends to the mean value and to the standard deviation of the vehicles velocities.
