FRP strengthening of concrete structures – design and practical emphasis in Sri Lanka

Abstract

FRP Strengthening has been developed worldwide as a mean of strengthening and retrofitting concrete structures throughout past few decades. The ever increasing loads on structures and change of use demands higher load carrying capacities. The use of FRP strengthening methods has enabled the use of existing structures thus saving millions, valuable material and valuable time will otherwise be spending on demolition and reconstruction. However lack of design guidance has been a critical issue in this area. The authors have carried-out a design and implementation of FRP strengthening of an existing two storey building to accommodate two more floors and a light weight roof. This paper discusses the design method, testing carried out and practical implications in FRP strengthening of concrete columns.
