Claim:
1. A fiber reinforced polymer composite structure comprising: a reinforced concrete column having a rectangular cross section with a top, a bottom, two opposite sides and two ends and an aspect ratio of 1.5:1 (length of sidewalls to thickness between the sidewalls) or greater, chamfered corners, and two or more arcuate cement segments disposed on each of said two opposite sides of said column and a single segment disposed on each of said ends; a fiber reinforced polymer material surrounding said column and said segments; one or more perpendicular passages perpendicular to and through said fiber reinforced polymer material between adjacent segments on each of said opposite sides of said column; and a steel bolt extending through each of said one or more passages and a nut for fastening said column, said segments or segment and said fiber reinforced polymer together under compression; in which each of said arcuate cement segments form a portion of a generally circular shape on said reinforced concrete column; and wherein an arcuate segment on each of said ends with an adjacent arcuate segment on each of said sidewalls form a semicircular shape abutting the two side and an end, and wherein the arcuate cement segments at the end are continuous over the reinforced concrete column and cover said chamfered corners at a predetermined depth.
