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.
Claims13
A reinforced concrete column adapted for use in supporting bridges and other structures, said reinforced concrete column comprising:
- a concrete column having a top, a bottom, an axis and a circumferential outer surface extending axially between said column top and bottom;
- a composite reinforcement layer surrounding said column wherein said composite reinforcement layer is in direct contact with said circumferential outer surface, said composite reinforcement layer comprising at least one fabric layer which is located within a resin matrix, said fabric layer having first and second parallel selvedges which extend around said circumferential outer surface in a direction substantially perpendicular to the axis of said concrete column to provide said reinforced concrete column.
