Application of Cathodic Protection for Prestressed-Concrete Structure

Development and Practical Application of a Lifetime Management System for Prestressed Concrete Bridges

A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

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...

Advantages of Large Strands in Precast/Prestressed Concrete Highway Application

The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...

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...
