Performance-Based Vibration Design Methodology for Pedestrian Bridges

In the design of pedestrian bridges, it is not uncommon for the size of primary structural members to be controlled by user-induced vibrations. Building codes published by various government agencies provide a range of limiting values for acceptable bridge fundamental frequency limits that may prove to be excessively conservative. For simply-supported bridge spans, a more efficient design can be developed through a performance-based approach which accounts for the dynamic response of a bridge subjected to a harmonic load function. The design methodology outlined in this paper determines the adequacy of a simply-supported bridge structure through the application of a damping-dependent frequency response curve, where pedestrian-induced structural acceleration is compared to a calculated allowable acceleration limit. The applicability of the design methodology is then quantified through a case study that addresses the analysis and design of a simply-supported steel pedestrian bridge in Southeast Asia.
