Recent surveys have indicated that between 30% and 40% of all bridges in North America are in various states of deterioration. Funding is limited owing to the existence of other deficient components of the transportation infrastructure. It is clear,

The objective of this paper is to assess the potential economic benefits from the use of high performance concrete (HPC) for continuous precast, prestressed I-girder highway bridges. Unlike the traditional approach of trial and error, this approach u

A simple method is proposed as a substitute for the usual process of factoring loads, performing a linear elastic analysis, and determining an envelope of the results. The method is based on statistical principles, but only a minimum knowledge of sta

Composite Construction in Steel and Concrete IV.
Test results are compared with theoretical predictions for a series of composite beams made with a pretensioned high-strength concrete tension flange, a corrugated steel web, and a reinforced concrete compression flange. The results from five tests i

I n order to perform an "exact" flexural analysis of a bonded prestressed concrete section, it is necessary to consider both the equilibrium of forces acting on the section and the compatibility of the strains. For this analysis, the actual stress-st

Offshore islands and structures require protection from wave and ice erosion. Protection has been traditionally provided by sandbags, concrete mats, or quarried rock. The results of a research program are presented in which a new form of artificial a
