Construction of Prestressed Concrete Pavement with Long Span

Design and implementation of a monitoring system applied to a long-span prestressed concrete bridge

Currently long-term monitoring systems are mandatory in major civil engineering structures like bridges, tunnels and dams. Generally, they monitor a set of physical, chemical and mechanical parameters in critical sections of the structure by incorporating appropriated sensors. The set of collected data demonstrates great potential in the prevention of damage and contributes to a more efficient ...

Construction assessment and long-term prediction of prestressed concrete bridges based on monitoring data

The long-term assessment of large civil infrastructures such as prestressed concrete bridges is a challenging task. The real time history related to the phased construction, the influence of the adopted construction method, the characterization of the employed concrete and the environmental conditions are crucial aspects for accurate predictions based on Finite Element Models. Data from long-te...

Prestressed Concrete Piles

A state of the art presentation on prestressed piling as used throughout the world is discussed in this General Report to the FIP Symposium on Mass-Produced Prestressed Precast Elements in Madrid, Spain, May 1968. Historical information, design data and notes along with manufacturing techniques, installation practices, discussion of problems and failures and a complete bibliography are all cove...

Ductility of Prestressed and Partially Prestressed Concrete Beam Sections

D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...
