Lack of adequate ductility in substandard reinforced concrete buildings is a major reason for significant amount of life and economic losses experienced during major earthquakes. Laboratory tests realized at member level (i.e. column and beam tests) show that external wrapping of potential plastic hinging regions of columns with Fiber Reinforced Polymer (FRP) sheets, can significantly enhance the ductility capacity. Thus, major seismic retrofitting documents available worldwide interpret this retrofit approach as a viable alternative and lay the rules for retrofit design with these materials. In this study, a very recent experimental activity that included the full-scale testing of a substandard building retrofitted with the above mentioned approach is briefly presented. Then, the performance prediction of the Turkish Seismic Design Code (2007) for this building is evaluated. Finally, a revision is proposed for the FRP effective rupture strain value defined by this code.
