Abstract
A shape modification of a wall-like column includes the preparation of the column by chamfering the corners and roughening the sides of cement segments thereto. The process requires a simple formwork in the form of generally circular PVC pipe segments which are cut to required shapes which are arcuate such as the segments of a circle, oval or even elliptical. After those forms formed from the PVC pipe affixed around the reinforced concrete column are then filled with grout/cement. A plurality of vertical steel strips are attached to the column by steel rod-like shear studs that extend through previously drilled passageways passing through the reinforced concrete column and segments. The reinforced concrete column is then strengthened by increasing the area of cross section and more importantly by confining the column and attached segments by FRP materials. In addition, the vertical strips with steel studs contribute to the column strengthening.
