In this paper, a relatively less studied class of structures is presented based on the research conducted on Florida's movable bridges over the last several years. Movable bridges consist of complex structural, mechanical and electrical systems that provide versatility to these bridges, but at the same time, create intermittent operational and maintenance challenges. Movable bridges have been designed and constructed for some time; however, there are fewer studies in the literature on movable bridges as compared to other bridge types. In addition, none of these studies provide a comprehensive documentation of issues related to the condition of movable bridge populations in conjunction with possible monitoring applications specific to these bridges. This paper characterises and documents these issues related to movable bridges considering both the mechanical and structural components. Considerations for designing a monitoring system for movable bridges are also presented based on inspection reports and expert opinions. The design and implementation of a monitoring system for a representative bascule bridge are presented along with long-term monitoring data. Various movable bridge characteristics such as opening/closing torque, bridge balance and friction are shown since these are critical for maintenance applications on mechanical components. Finally, the impact of environmental effects (such as wind and temperature) on bridge mechanical characteristics is demonstrated by analysing monitoring data for more than 1000 opening/closing events.

“…The analysis of VIS from a resilience engineering perspective is an emerging discourse for both researchers and policy makers. Various studies were recently conducted to analyse the performance and reliability of different types of vital infrastructures such as transport and water systems (Frangopol and Bocchini, 2012;Guidotti et al, 2017;Gardoni, 2018). While the literature on resilience engineering has been burgeoning, existing literature either focus on defining and conceptualizing resilience, and provide little guidance for designing resilient infrastructures.…”

Abstract. Infrastructure systems are inextricably tied to society by providing a variety of vital services. These systems play a fundamental role in reducing the vulnerability of communities and increasing their resilience to natural and human-induced hazards. While diverse definitions of the resilience engineering concept exist for the infrastructures, analysing resilience of these systems within cross sectoral and interdisciplinary perspectives remains limited and fragmented in research and practice. This review synthesizes and complements existing knowledge in designing resilient vital infrastructures with the aim to assist researchers and policy makers by identifying: (1) key conceptual tensions and challenges that arise when designing resilient infrastructure systems; (2) engineering and non-engineering based measures to enhance resilience of the vital infrastructures, including the best recent practices available; and (3) opportunities for future research in this field. Results from a systematic literature review combined with expert interviews are integrated into a conceptual framework in which infrastructures are defined as a conglomeration of interdependent social, ecological, and technical systems. Our results indicate that conceptual and practical challenges in designing resilient infrastructures continue to exist, hence these systems are still being built without taking resilience explicitly into account. A review of available measures and recent applications shows that these measures have not been widely applied in designing different systems. To advance our understanding of the resilience engineering concept for infrastructure systems, main pressing topics to address evolve around the: (i) integration of the combined social, ecological and technical resilience of infrastructure systems, focusing on cascading effects of failures and dependencies across these complex systems; and (ii) development of new technology to identify the factors that create different recovery characteristics for these socio-ecological-technical systems.

“…Much research has been carried out to determine a life-cycle safety analysis of infrastructure assets, in order to determine likely periods of intervention. These methods include using advanced probabilistic methods (Frangopol & Bocchini, 2012;Frangopol, 2011), to using various methods of linear, nonlinear, and dynamic programming (Ng et al, 2011;Medury & Madanat, 2013).…”

Limitation of resources and variations of interest or priority of different stakeholders of road infrastructure networks often lead to multiple considerations of intervention options. It is of interest to identify the best available intervention or investment option under a multi-criteria framework. Markers of performance may be varied and the approach towards maintenance management may have different philosophies based on specific organisational structures of governance. This paper presents a methodology for cross-asset management that caters to different maintenance management systems without modification. Optimisation approaches and effective implementation methods are identified. Practical implementation guidelines of the developed framework are illustrated.
