Design of fibre reinforced polymer (FRP) strengthened beam for flexure

Abstract

Nowadays, upgrading civil engineering structures is a very important issue, particularly for concrete bridges and buildings. For concrete bridges, increase in traffic load and deterioration caused by environmental factors are the two main reasons for a decrease in safety. FRP strengthening technique is widely gaining appeal in civil engineering infrastructures due to its superior properties and ease of construction and strengthening. However, the application of this technique is very limited in Sri Lanka. This is mainly due to lack of knowledge about FRP applications, selection of materials and also design procedures. The paper presents the background and detailed design procedures for FRP strengthened beam subjected to flexure.
