Book excerpt: As a result of increasing highway construction and expansion, a corresponding need to increase traffic capacity in heavily populated areas, and ever-increasing constraints on available land for transportation use, there has been an increasing demand for alignment geometries and bridge configurations that result in more efficient use of available space. As a result of this demand, there has been a steady increase in the use of curved girder bridges over the past 30 years. Despites extensive research relating to the behavior of these types of structures, a thorough understanding of curved girder bridge response, especially relating to dynamic behavior, is still incomplete. To develop an improved, rational set of design guidelines, the Federal Highway Administration (FHWA) initiated the Curved Steel Bridge Research Project in 1992. As part of this project, FHWA constructed a full-scale model of a curved steel girder bridge at its Turner-Fairbank Structures Laboratory. This full-scale model made it possible to conduct numerous tests and collect a significant amount of data relating to the static behavior of a curved girder bridge. However, relatively little information has been available on the dynamic response of curved girder bridges and this type of information is needed before a complete design specification can be developed. The objective of this study was to develop a finite element model using SAP2000 that could be used for predicting and evaluating the dynamic response of a curved girder bridge. Models of the FHWA curved girder bridge were developed using both beam and shell elements and response information compared with experimental data and with analytical data from other finite element codes. The experimental data were obtained during dynamic testing of the full-scale bridge in the Turner-Fairbank Structures Laboratory and analytical response information was provided from finite element models of the bridge using ANSYS and ABAQUS. The primary focus of the study was the prediction of frequencies and mode shapes of the full-scale curved girder both with and without a deck. Both experimental and analytical frequencies and mode shapes were calculated and compared. Although the more refined ANSYS and ABAQUS models provided response data that compared more favorably with the experimental data, the SAP2000 models were found to be more than adequate for predicting the lower modes and frequencies of the bridge.

This volume consists of a book of extended abstracts and a USB card containing the full papers of 571 contributions presented at IABMAS 2020, including the T.Y. Lin Lecture, 9 Keynote Lectures, and 561 technical papers from 40 countries. The contributions presented at IABMAS 2020 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of maintenance, safety, management, life-cycle sustainability and technological innovations of bridges. Major topics include: advanced bridge design, construction and maintenance approaches, safety, reliability and risk evaluation, life-cycle management, life-cycle sustainability, standardization, analytical models, bridge management systems, service life prediction, maintenance and management strategies, structural health monitoring, non-destructive testing and field testing, safety, resilience, robustness and redundancy, durability enhancement, repair and rehabilitation, fatigue and corrosion, extreme loads, and application of information and computer technology and artificial intelligence for bridges, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of making more rational decisions on maintenance, safety, management, life-cycle sustainability and technological innovations of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including engineers, researchers, academics and students from all areas of bridge engineering.

Available in PDF, EPUB and Kindle. Book excerpt: The Wolf Creek Bridge is a curved, multi-girder three span steel composite bridge located south of Narrows, Virginia, that was completed in 2006. A finite element (FE) model of the bridge revealed that pier flexibility may be important in modeling the bridge. In addition, questions have been raised as to the effectiveness of the C15x33 diaphragms in providing lateral transfer of loads between members. This study was conducted as Phase II of a project for which the overall goal was to use field testing to obtain a better understanding of the behavior of multi-span curved girder bridges. The Phase I study was published separately (Turnage and Baber, 2009). During Phase II, an array of 49 strain gages was installed on the superstructure of the bridge: 34 gages were installed on the four girders at the mid-point of the center span, and 15 gages were installed on the three diaphragm members located closest to mid-span. The bridge was then subjected to static and dynamic applications of a loaded dump truck for which the axle loads were quite close to those of an HS-20 truck. The static strains were measured when the truck was located at 19 different locations on the inner and outer lanes. The dynamic strains were measured under the truck crossing the bridge at normal traffic speed for the structure. The static loading was then replicated on the FE model. The measured static strains were compared with the strains computed from the FE model. Both measured and computed strains on the girders were used to estimate distribution factors, which were compared to evaluate the effectiveness of moment transfer between girders. The measured static and dynamic strains were also compared to estimate dynamic amplification factors. Finally, measured and computed diaphragm strains were compared to evaluate the FE model's diaphragm girder approximation. The study found that the diaphragms transfer relatively little load from the loaded lane toward the unloaded lane but slightly more load transfers toward the outer girders than toward the inner girders. Further, the FE model predicts slightly greater transfer of load between girders than was measured in the field, suggesting that the model overestimates the stiffness of the diaphragm to girder connection. Finally, the measured strains and strains computed using the FE model predict different neutral axis locations. Following additional numerical studies, it was concluded that the FE model predicted the neutral axis to be higher than it should be, based upon transformed section calculations. In addition, full composite action based upon transformed section calculations should result in a neutral axis location higher than was determined from field data measurements. This suggests that some slip might be occurring between the girders and the haunch.
