Introduction

Nowadays, many buildings need to be upgraded, especially in earthquake-prone areas, because of increased strength demands introduced by modern design codes or damage due to strong earthquakes. As a result, many techniques have been developed to improve the performance of the existing buildings. There is a wide range of applications of fiber-reinforced polymers (FRPs) in the form of rebars, plates, and sheets for the strengthening of the existing buildings. These materials can be used for flexural and/or shear strengthening of existing structures, and a comprehensive description of this technique can be found in Essay 382,109 “Retrofitting and Strengthening of Contemporary Structures: Materials Used.”

In this entry, special emphasis is given on the technique of reinforced concrete (RC) jacketing. RC jacketing is a widespread technique used for the strengthening of...
