There is a concern with worldwide deterioration of highway bridges, particularly reinforced concrete. Due to the corrosive nature of steel re-bars used in concrete bridge decks, the service-life of these bridges is reduced. The advantages of advanced composite materials (ACM) over conventional materials motivate their use in highway bridges for rehabilitation and replacement of structures. Howe...

Aging is associated with decline in a multitude of cognitive processes and brain functions. However, a growing body of literature suggests that agerelated decline in cognition can sometimes be reduced through experience, cognitive training, and other interventions such as fitness training. Research on cognitive training and expertise has suggested that age-related cognitive sparing is often qui...

BACKGROUND Aging may cause various functional abilities gradually deteriorate. With changes in social forms, the trend of functional fitness decline will change accordingly. Therefore, this study endeavored to identify the trends in functional fitness decline by comparing the differences in the functional fitness of females in various age groups. METHODS Thirty six healthy females were divide...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

Bridges are critical assets for the safe, reliable and functional operation of transportation networks. Infrastructure asset managers responsible ensuring that these bridges adhere to rigorous safety standards using finite resources available agencies. To facilitate strategy development present decisions stakeholders, a life cycle analysis is commonly performed. Many bridge owners use stochasti...

Corrosion directly affects the structural stiffness of a steel element, reducing thickness, thus inertia, due to gradual deterioration material. Quickly identifying corrosion damage structure is challenge in coastal environments since progresses rapidly, and traditional methods inspection diagnosis are time-consuming costly. This an important issue; therefore, characterization level represents ...

Assessment of a single bridge and management system for all bridges in the network is still major challenge, although much research has been carried out implemented existing networks over last four decades. This paper presents case study long-span arch bridge, Maslenica Motorway Bridge, located multi-hazard maritime environment. Although special attention was paid to durability during design, r...

Life cycle monitoring of civil infrastructure such as bridges and buildings is critical to the long-term operational cost and safety of aging structures. Nevertheless, there is no commonly accepted and recognized way to perform automated monitoring of bridges. One of the important issues is the cost of the data acquisition subsystem and its installation and maintenance costs, which are tightly ...

At present, the main methods of bridge condition assessment are reliability analysis and analytic hierarchy process method. Robustness, as a measure structural ability to maintain performance after occurrence variations, can provide different perspective based more on property itself. Although robustness has been mainly used in design optimization against progressive collapse extreme events, it...
