Sažetak
Due to their slenderness, pedestrian bridges may vibrate significantly under pedestrian traffic. Many researches in the past few decades deal with the problem of predicting the vibration response induced by human activity reliably. Most of the codes in the field of footbridge design define certain pedestrian comfort criteria which have to be satisfied to fulfil the serviceability in relation to vibration. The main disadvantage of the current European codes (Eurocodes) is lack of defined dynamic models of pedestrian loads for the serviceability state verification in relation with vibration. In this paper a design procedure (with load models recommendation) for verification of the serviceability limit state related to vibration due to pedestrians is proposed. According to the proposed procedure the serviceability verification on a model of a reinforced concrete pedestrian bridge in the Maksimir Park in Zagreb is conducted.
