    New methods are required for sustainable and economical management of bridges. Efficient management can be achieved by a detailed understanding of bridge behavior through monitoring and model-based data interpretation. This paper presents a methodology to evaluate the fatigue safety of existing bridges based on conducting measurements onsite and interpreting measurement data using physics-based behavior models. The methodology combines data from different nondestructive measurements with structural models to develop a suitable set of feasible models that describe accurately structural behavior. The methodology is illustrated with a case study of a composite steel-concrete road viaduct instrumented with acoustic emission channels and strain gauges. Information from measurements is used to update a set of structural models and then evaluate the fatigue safety of the viaduct. While commonly used curve-fitting methods are inaccurate, this methodology is useful to accurately employ the measured behavior of existing civil infrastructure for evaluating nonaccessible elements and scheduling inspections and decision-making related to actions such as strengthening and retrofit.

    Item type: Journal Article

    Journal of Bridge Engineering
    With the development of new materials and advanced structural analysis, alongside increasing aesthetic requirements, recent years have witnessed a trend toward longer, taller, and lighter footbridges. Different from vehicular bridges, footbridges carry relatively small service loads and are more susceptible to vibrations, due to their lower stiffness, damping, and modal mass. More often than not, vibration serviceability limit state governs the design of footbridges. Providing an accurate evaluation of vibration serviceability performance of existing bridges requires techniques that can include modeling and measurement uncertainties. In this paper, a population-based method called error-domain model falsification (EDMF) is used to assess the vibration serviceability for two pedestrian bridges: Fort Siloso Skywalk located in Singapore and the Dowling Hall Footbridge located at Tufts University in the United States. The unknown properties of the footbridges are identified using the ambient vibration data measured on site. This method is also compared with two other data-interpretation methodologies, that is, residual minimization and traditional Bayesian model updating. The findings show that, through explicitly accounting for measurement and modeling uncertainties, EDMF can provide more accurate identification and prediction results for vibration serviceability assessment of pedestrian bridges. © 2020 American Society of Civil Engineers.

  • Full-Scale Testing and Stringer Connection Fatigue Analysis of a Historical Swiss Military Bridge for the Rhaetian Railway
    Item type: Journal Article
    Fleming, Patrick Hugh (2022)
    Journal of Bridge Engineering
    The stringer connections of a historical "Model 1936" Swiss military bridge are investigated through a full-scale field-testing program, with the aim of clarifying modeling uncertainties and enabling a standard fatigue analysis for practicing engineers. Due to global bending, axial tension forces arise in the bridge's stringers, which were not considered in original dimensioning. In contrast to historical steel bridges with typical riveted connections, Fritz Stussi designed the "Model 1936" military bridge with custom bolts and nuts. Unlike rivets, these custom bolts and nuts can accommodate prestressing and enhance connection stiffness and thereby encourage potential fatigue problems. Field tests with strain measurements along the stringer beams themselves were used to determine bending moment profiles and connection stiffness parameters, and to calibrate a static model of the bridge. Following the nominal stress method with a standard load model, a basic finite-element analysis indicates that the stress range in the bridge's stringer connections lies within the prescribed fatigue limits from standards. The implementation of a five-year periodic inspection plan further ensures the bridge's safe use and long-term integrity.
