| Abstract | An experimental study was performed to examine the enhancement in axial capacity of HP-CFRP wrapped reinforced concrete columns subjected to simulated air blast. Tests were conducted in an academic testing environment using a shock tube. Four half scale reinforced concrete columns (150 mm × 150 mm × 2438 mm) were tested under single blast shot. Two columns were externally strengthened with UD [0/90] W [±45]₂ UD [0] CFRP sheets, and the other two columns were left unprotected to serve as control columns. The columns were subjected to axial compression of 50 % of the column ultimate axial capacity. In order to examine the residual axial capacity of the tested columns, they were loaded axially up to ultimate load capacity after the application of the blast load. The damage generated at the critical zone was completely prevented by the application of the CFRP jacketing. It is found that columns externally strengthened with CFRP laminate are capable to carry high axial load compared to unprotected columns after a major blast event. |
