DUCTILITY OF PRESTRESSED BRIDGES USING CFRP STRANDS

In the last few years, researchers have been trying to improve the flexural ductility of CFRP prestressed concrete structures using various techniques. Taniguchi, et al. proved that ductility characteristics similar to those of steel-reinforced members could be achieved by making the members undergo flexural compression failure. The main objectives of this investigation, currently underway at Lawrence Technological University (LTU), Southfield, Michigan, are to examine the ductility of entire prestressed concrete bridge superstructures, with both rectangular and skew geometries (spans crossing at angles other than 90 degree to the abutments), and to introduce a construction and design approach that exhibits a reasonable increase in absorbed energy. This article presents some of the test results.
