PERFORMANCE OF CARBON FIBER AS LATERAL TIES IN SHORT AXIALLY LOADED CONCRETE COLUMNS

An experimental program to investigate the structural performance of CFRP as lateral tie in concrete column is conducted. The experimental program consist of twenty one number of column fabricated and tested experimentally under axial load. Specimens were divided into four groups and each group except group 1 consists of six columns. Group 1 consist of reference columns; three plain concrete and six specimen reinforced with steel reinforcement. Group 2 columns were reinforced with CFRP lateral tie and columns of group 3 were reinforced with CFRP lateral ties except end ties to solve fabrication issue. Size of all the columns was kept same, 600 mm in height and 150 in mm diameter. Results shows a significant increase in axial capacity of column tied with CFRP lateral ties. Column with end steel ties shows similar behaviour as CFRP tied column.
