“…Therefore, the ability to confidently evaluate the decreased load carrying capacity of the damaged bridge with respect to its performance is essential for effective and efficient bridge management. The Hercílio Luz Bridge (HLB), which is an eye-bar chain suspension bridge located between the Santa Catarina Island and the mainland of Brazil, was completely closed to traffic in 1991 due to high corrosion levels and deterioration of its critical members (Carvalho et al, 2017). Truck accident is the third leading cause of bridge failure or collapse in the United States.…”

A practical long term structural health monitoring program must be based on reasonable field capabilities, the needs of the bridge owner, and the anticipated structural behavior unique to the structure. Each sensor installed as part of the monitoring program should provide information directly in response to operational needs related to the structure's short term and long term performance. A thoughtfully considered instrumentation plan developed in cooperation with the bridge designer, bridge manager, bridge maintenance operator and academic researchers will provide data to enhance both the state of the practice and state of the art for the bridge structural design, management and maintenance. Monitoring a bridge's structural response has the potential to (a) detect the presence of structural changes for condition assessment, (b) inform the bridge manger to assist in daily operational decision-making and (c) validate the structural design assumptions and (d) refine a structural model of the bridge to be used for performance prediction. The excitation for these responses typically comes from traffic or environmental demands. Vertical lift bridges provide a unique opportunity for structural health monitoring based on the dynamic response due to the frequent and repeated impact imparted on the structure each time the lift span opens and closes. In this paper, a structural health monitoring system designed to provide valuable information for design verification, structural model calibration, fatigue monitoring, and operational decision-making support for the reconstructed Memorial Bridge carrying US Route 1 between Portsmouth, New Hampshire and Kittery, Maine. This paper will detail the development of the sensor layout including input from stakeholders, accessibility issues and complementary and contradicting objectives. A set of structural models with varying degrees on complexity were created based on the structural performance objectives. The data collected during a pseudo-static truck load test was used to calibrate the structural models of the bridge and to select the appropriate model for each post-processing and decision-making tools related to structural performance.

“…To maintain structural integrity and increase service life, a complete rehabilitation project was developed and currently underway for the bridge, including the replacement of compromised members (ie, sectional area loss due to corrosion more than 10%) and repair of the remaining members. 38 The rehabilitation complies with the provisions of the Brazilian codes and Eurocode, although the bridge was originally completed according to the requirements of the American Association of State Highway and Transportation Officials at the time. According to the final rehabilitation design, the floor beam, stringer, eye-bar chain, and north sidewalk that are marked in red in Figure 6C are replaced by new members, and the remaining members are retained originally after repair or maintenance.…”

Increasing traffic demands (ie, load intensity and operational life) on ancient riveted metallic bridges and the fact that these bridges were not explicitly designed against fatigue make the fatigue performance assessment and fatigue life prediction of riveted bridges a concern. This paper proposes a global‐local fatigue analysis method that integrates beam‐to‐solid submodeling, elastoplastic of material in local region, and local fatigue life prediction approach. The proposed beam‐to‐solid submodeling can recognize accuracy local stress/strain information accompanying with the global structural effect on the fatigue response of local riveted joints. The fatigue life is predicted based on cumulative damage rule, local strains, and number of cycles with consideration of traffic data, where the relation between the fatigue life and local strain is derived according to the Basquin and Manson‐Coffin law. Besides, the elastoplastic of material is considered. The proposed methodology for fatigue life prediction based on local strain parameter and the Palmgren‐Miner linear damage hypothesis is implemented in a case study of an ancient riveted bridge.

“…One of the passages comments on the Garabit Viaduct, designed by G. Eifel, the engineer who designed and lent his name to the tower in Paris. I use it to bring to the reader another two examples of bridges which could well be cited in this book: Ponte Hercílio Luz (designed by Robinson e Steinman, see H. Carvalho et al, 2017), in Florianópolis and Ponte Maria Pia (designed by Eiffel and Théophile Seyrig), in Porto, Figure 3. Chapter 3 is devoted to the disciplines of theory of structures and applied mechanics, including an account on the born of the engineering handbooks, the main ones being described.…”
