Bridge Bed Strengthening, Disaster Prevention due to Scouring

Data Exchange Platform for Bridge Disaster Prevention Using Intelligent Agent

Due to the location and environment of Taiwan, the frequency of nature disaster is high and the caused damages to the human life, properties and transportation facilities are serious. Considering the disaster prevention of bridge structures caused by earthquake, scour, debris flow, corrosion and senescence, literatures involving the developed bridge management information systems and the bridge...

Reducing Local Scouring at Bridge Piles Using Collars and Geobags

The present study examines the use of collars and geobags for reducing local scour around bridge piles. The efficiency of collars and geobags was studied experimentally. The data from the experiments were compared with data from earlier studies on the use of single piles with a collar and with a geobag. The results showed that using a combination of a steel collar and a geobag yields the most s...

Connective tissue disease due to intentional inhalation of scouring powder.

There have been reports in the literature of acute and chronic silicosis and connective tissue disease induced by occupational exposure to silica in factories producing scouring powder. Reports of connective tissue diseases induced by intentional inhalation of such a powder are rare and perhaps underestimated. We report the case of a young woman who developed Sharp's syndrome 5 yrs after diagno...

Bed Scouring During the Release of an Ice Jam

A model is developed for simulating changes in river bed morphology as a result of bed scouring during the release of an ice jam. The model couples a non-hydrostatic hydrodynamic model with the processes of erosion and deposition through a grid expansion technique. The actual movement of bed load is implemented by reconstructing the river bed in piecewise linear elements in order to bypass the ...

Strengthening of Bridge Slabs with Frp Systems

Advances in the fields of polymers and composites have resulted in a major development of high strength fibre reinforced polymers (FRP). These materials offer great potential for cost-effective retrofitting of concrete structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted at the University of Manitoba in Winnipeg, Manitoba, Can...
