Structural Repair and Strengthening of RC Elements with Concrete Jacketing
Extensive investigations on repair and retrofitting of reinforced concrete elements have been undertaken in recent years and many methods have been developed, tested and reported in the literature. The reinforced concrete jacketing has been considered as one of the important and used methods to correct design errors, deficient concrete production and execution processes, repair damage after earthquake, accidents or in the cases where it is needed to proceed with the change in the functionality of the structure etc. In this chapter is performed a brief review of the literature concerning the numerical and experimental research performed as well as the detailing recommendation and general criteria and procedures used in the concrete jacketing. In the end it is presented an example of an application of RC jacketing to correct a soft-storey mechanism in an existent RC building and it is presented the recent experience in the use of reinforced concrete jacketing in the Kathmandu University after the 2015 Gorkha Earthquake.
