Simplified procedure for maximum acceleration determination on simple bridge structures
A verification of the comfort criteria for serviceability limit state due to pedestrians should be done if the fundamental frequencies of the bridge deck are below values determined in bridge design codes. Nowadays, the comfort criteria is usually defined as maximum acceptable acceleration of any part of the bridge deck. Dynamic load models of single pedestrian and group of pedestrians are determined as single pulsating force moving along the bridge. Though the model of moving pulsating force is similar to real character of pedestrian loading (walking along the bridge) acceleration assessment is not simple because the lack of easily available software able to conduct dynamic analysis due to moving loads. The process of bridge designing can be significantly accelerated if a simplified procedure for maximum acceleration determination is established. In this paper an improved simplified procedure based on response of single degree of freedom oscillator i.e. response of a structure due to pulsating stationary force of unlimited duration is proposed.
