Abstract: Pultruded glass fibre reinforced polymer (GFRP) is a strong, light, and durable material that is very well suited to modular structural forms. The replacement of aged and deteriorated small footbridges is an ideal use for such structures. However, GFRP has low stiffness this and the typical low mass of GFRP structures, mean that they can be susceptible to human-induced vibration. Further, the vibration design rules for footbridges have evolved over the years from experience with steel and concrete structural forms. Consequently there is a need to investigate the suitability of GFRP footbridges and the applicability of current design rules. A team at Monash University has recently constructed a 9 m long orthotropic deck pultruded bonded GFRP footbridge to investigate these issues. Extensive material testing and full-scale structure testing has been carried out to establish the overall structural behaviour accurately. This paper explains the design and construction of the footbridge, and reports the results of the static performance assessments. Bond performance, shear lag, and deck-beam composite action are all examined under uniform load and four-point bending tests. This paper also reports the results of extensive experimental modal testing and numerical modelling of the structure. Further, a novel sequence of human walking trials has been performed to assess the vibration performance under real loading conditions. The modelling of human-induced vibration and the response of the structure is also considered in this work. The results will assist in developing improved guidelines for the design and construction of such structures.

Abstract: Traffic load is a highly variable parameter in the safety assessment of bridges. Its accurate assessment is important to avoid unnecessary and expensive rehabilitation measures for existing structures. Traffic microsimulation offers a comprehensive approach to the modelling of traffic. It is based on in idual vehicle behaviour, with parameters that account for differences in vehicle type and driver behaviour. It inherently captures both free-flowing and congested traffic states, offering a more realistic picture of these states and their consequent loading on bridges. Further, microsimulation enables potential traffic management methods to be examined to estimate their effectiveness in mitigating critical loading scenarios. This work summarizes some recent results from the use of traffic microsimulation. Comparison with the Eurocode for bridge loading codes is made and various traffic management strategies are investigated for their effect on loading. The possibility of bridge-to-vehicle communication is explored, as is the use of lane change restrictions zones before the bridge. A bridge load control system is also examined. The results are persuasive: it is shown that microsimulation can be an important tool in more accurate assessment of the actual loading experienced by bridges, as well as providing a means to explore load control through traffic management. Given the ageing bridge stock and increasing financial limitations of the developed world, this work offers bridge owners a means of ensuring safety, whilst reducing costs.

Abstract: Accurate estimates of characteristic bridge load effects are required for efficient design and assessment of bridges, and long-run traffic simulations are an effective method for estimating the effects. For multi-lane same-direction traffic, truck weights and locations on the bridge are correlated and this affects the calculated load effects. Scenario Modelling is a recently developed method, which uses weigh-in-motion data to simulate multi-lane same-direction traffic while maintaining location and weight correlations. It has been unclear however, whether the method may produce unrealistic driver behaviour when extrapolating beyond the weigh-in-motion measuring period. As weighin-motion databases with more than about a year of data are not available, a microsimulation traffic model, which can simulate driver behaviour, is used here to assess the accuracy of extrapolating traffic effects using Scenario Modelling. The microsimulation is used to generate an extended reference dataset against which the results of Scenario Modelling are compared. It is found that the characteristic load effects obtained using Scenario Modelling compare well with the reference dataset. As a result, for the first time researchers and practitioners can model two-lane same-direction traffic loading on bridges while being confident that the approach is generating accurate estimates of characteristic load effects as well as effectively reproducing the complex traffic correlations involved.

Abstract: For long-span bridges, congested traffic forms the governing traffic load condition. This paper reviews the current state of the art and the deficiencies in the data upon which the modelling of congestion is typically based. It is proposed that a vision system be adopted to collect statistical information for the parameters required to properly calibrate congestion models. Conventional methods for the detection of vehicle features in images are described, applied to s le images, and criticised. It is concluded that vision-based methods are a viable tool for gathering inter-vehicle gap data, but that existing methods of wheel detection are not sufficient. Therefore the development of a new technique for wheel detection is recommended and some suitable attributes identified.

Abstract: Bipedal models for walkers, originally developed in the research field of biomechanics, have been identified as potential candidates for modelling pedestrians in structural engineering applications. These models provide insight into both the kinetics and kinematics of walking locomotion and are considered to have a significant potential to improve the vibration serviceability assessment of civil engineering structures. Despite this notion, the ability of the bipedal models to represent the key features of the walking gait and natural variability within the pedestrian population are still under-researched. This paper critically evaluates the performance of two bipedal models with rigid legs to realistically both reproduce key features of an in idual pedestrian’s walking gait and represent a wide range of in iduals. The evaluation is performed for walking on a rigid, rather than vibrating, structure due to the availability of experimental data and expectation that successful modelling on rigid surfaces is a necessary condition for progressing towards modelling on the vibrating structures. Ready-to-use equations are provided and the ability of the models to represent the kinematics and kinetics of in idual pedestrians as well as the inter-subject variability typical of the human population is critically evaluated. It was found that the two models could generate realistic combinations of the gait parameters and their correlations, but are less successful in reproducing genuine kinetic and kinematics profiles.
