Abstract

This paper presents experimental studies on investigating the seismic retrofit performance of reinforced concrete rectangular columns with poor lap-splice details using GFRP wrapping. Six columns have been tested. The GFRP retrofitted columns with same 7.5 mm thickness have two section shapes, i.e., rectangular and elliptical sections. The GFRP height was changed from 450 mm to 900 mm. The performance of GFRP retrofitted columns which have different shapes and height are verified.
