| Abstract | ||
| There are a many situations where it becomes necessary to increase the load carrying capacity of a structure. In the past, the increase in strength has been provided by casting additional reinforced concrete or dowelling in additional reinforcement. Actually there is a growing use of externally bonded fibre composites (FRPs) to strengthen a wide range of structural elements. Many experimental work show that FRP composites, used in the beams as external tensile reinforcement, increase the strength and the stiffness of the structure. This paper presents the flexural strength enhancement provided by FRP laminate. The analysis is performed using finite element method. Two dimensional plane stress element with layered cross section are used for the discretisation of concrete. The modifications of neutral axis position and the materials properties during the loading process are taken into account. The predicted results show an increase of the carying capacity of the streingthened beams. They are in good correlation with those of literature review. | ||
