Research And Application Of Prestressed CFRP Tendon Tension Anchorage System

As a performance of traditional composites, reinforced concrete and prestressedconcrete was widely used in modern engineering structures since it appears, and structureslowly from a small structure to the development of large-scale structure. The traditionalbasic component reinforcement material reinforced, steel strand and parallel wire. Decades,with the depth of research and applications, reinforced and prestressed concrete structuresshortcomings increasingly exposed, especially in harsh environments, just corrosionproblem is very serious, and thus triggered a series of unfavorable factors are cause thestructure carrying capacity and the normal use of the ability to reduce the root causes,which had structural reinforcement.In many composite materials, new materials, fiber reinforced plastics (full nameFiber Reinfoced Plastics, or Fiber Reinfoced Polymer of FRP) for its lightweight, highstrength, corrosion resistance, non-magnetic, anti-fatigue characteristics stand out muchdomestic favor of outer researchers.This article relying Guangdong ProvincialCommunications Technology project "tensioning the tendons of the non-metallic materialstechnology, in combination with existing research at home and abroad on the basis of theresults for the the GFRP system of anchorage theoretical analysis, finite elementsimulation analysis, experimental research CFRP prestressed beam theory andexperimental research, to last tensioned anchoring technology research and engineeringapplications, has made substantial breakthroughs in some key technology issues, has beenformed from the anchorage of GFRP and CFRP prestressed beam with production to thetensioning process research and application of a complete set of tension anchorage system.Research and will eventually be applied to actual engineering Songshuao Bridge. Newbridges after FRP prestressing technology has played an important role in the reference.
