Surface Characteristics of Scouring at Bridge Elements
Bridge Abutment Pier Scour Clear water Countermeasure
2009/10/9
Infrastructural elements of bridges mounted in alluvial stream beds are susceptible to scouring. Decisionmaking for the type and placement practice of relevant countermeasures to be implemented agains...
The use of helical spring and fluid damper isolation systems for bridge structures subjected to vertical ground acceleration
Seismic isolated structures dynamic analysis vertical motion helical spring
2009/2/20
In this study a combination of helical springs and fluid dampers are proposed as isolation and energy dissipation devices for bridges subjected to earthquake loads. Vertical helical springs are placed...
Computer-aided limit states analysis of bridge abutments
Bridge abutment foundation limit-state-design soil-structure-interaction
2009/2/20
This paper presents a computer program developed for limit states analysis of abutments. The program can perform both structural and geotechnical analysis of bridge abutments and check their resistanc...
Common pathologies in RC bridge structures: a statistical analysis
Common pathologies RC bridge structures
2009/2/17
One of the main tasks in bridge engineering is to maintain the existing bridge stock according to current and predicted traffic and safety requirements. Bridges deterioration commonly occurs due to a ...
Research on seismic safety, retrofit, and design of a steel cable-stayed bridge
retrofit design steel cable-stayed bridge
2009/1/15
After the 1995 Great Hanshin Earthquake, Japanese design specification of highway bridges was revised and many piers and bearing supports have been retrofitted. Large span bridges such as arch, truss,...
Research on Moving Force Estimation of the Bridge Structure using the Adaptive Input Estimation Method
Bridge Structure Adaptive Input Estimation Method
2009/1/14
An on-line adaptive input estimation method that estimates the moving force inputs of the bridge structure is presented in this research. By using the inverse method, input forces acting on bridge str...
