Abstract

Strengthening of RC piers using fiber confinement to improve shear capacity and ductility has become more frequent in actual application. A new high fracturing strain fiber material, Polyethylene Terephthalate (PET), whose elastic modulus and fracture strain are 6.7 GPa and 13.8%, respectively has been investigated for its applicability for RC piers strengthening purpose. Experimental results showed PET fiber is less likely to rupture before the pre-defined ultimate state of strengthened structure is reached. The continuous fiber strain development allows further prediction of concrete damage and shear deformation based on truss mechanism model. A model for shear deformation was proposed and could predict the shear deformation post-flexural yielding and shear yielding. The shear deformation model can be a significant contribution in determining loaddisplacement curve for performance index in the performance based design.
