Opis

This book reports an investigation into the strength and ductility of Carbon fiber reinforced polymer (FRP) confined concrete columns. The investigation included an extensive experimental test program, the collection of a most updated database, assessment of existing strength models using the database, and development of a unified strength model. The test results demonstrated that the corner radius ratio is proportional to the increase in the confined concrete strength. Furthermore, it is revealed and explained that confinement provided by a jacket with sharp corners is insignificant in increasing the strength of columns but significant in increasing the ductility of columns. The unified strength model is applicable to both circular and square columns and performs well in comparison with the existing models.
