Abstract
Reinforced concrete columns wherein the exterior surface of the concrete column is wrapped with a composite reinforcement layer. The composite reinforcement layer includes at least one fabric layer which is located within a resin matrix. The fabric layer has first and second parallel selvedges which extend around the circumferential outer surface of the column in a direction substantially perpendicular to the column axis. Specific weave patterns are disclosed. The composite reinforcement layer provides a quick, simple and effective means for increasing the resistance of concrete columns to failure during the application of asymmetric loads.
