Abstract
Significant amount of research work has been carried out in recent years to develop various strengthening and rehabilitation techniques to improve the seismic performance of structures. HFRECL has started to be used to increase the flexural potency of members. To increase flexural power, the HFRECL should be glued to the member in the way that fibres are parallel to the direction of the principal stress. Basically the technique involves gluing steel plates or fiber reinforced polymer (HFRECL) plates to the surface of the concrete. The plates then act compositely with the concrete and help to bear the loads. Each material has its specific advantages and disadvantages. Steel plates have been used for many years and are very successful to use as bonding reinforcement. However, they are heavy to transport and install, prone to corrosion and delivery length of plates are limited. The aim of the present work is to study the behaviour of reinforced concrete columns strengthened using Glass Fibre Reinforced Polymer (GFRP) and Carbon Fibre Reinforced Polymer (CFRP) subjected to axial loading. The basic conceptual idea is to use HFRECL only in those zones of the structure where the outstanding HFRECL properties in terms of durability and strength are fully exploited; i.e. HFRECL is used to “harden” the zones where the structure is exposed to severe environmental conditions (ex., deicing salts, marine environment) and high mechanical loading (ex. impact, concentrated loads, fatigue). The energy absorbed by the column wrapped with both GFRP and CFRP was much superior than the column without FRP wrapping.
