EXPERIMENTAL STUDY ON EFFECT OF LATERAL RESTRICTION OF HIGH STRENGTH PRESTRESSED CONCRETE POLE ABOUT BENDING DEFORMATION PERFORMANCE

Abstract

This paper describes the results of experimental study on effect of lateral restriction of prestressed concrete poles using high strength concrete about bending deformation performance. I paid my attention to two types for lateral restriction and performed bending tests for external force to twice the design load. As a result, according to each form, I found two types at the time of destruction and found the force-drift angle relationship and the maximum ductility factor with ability of energy absorption. I particularly clarified the difference in deformation performance after first crack occurred.
