Abstract
In earthquake resistant design, it is important to ensure the ductility in the structure, i.e., the structure should be able to deform inelastically and dissipate energy without causing collapse. In frame structure, the bending moment and shear force are maximum in the junction area. So beam-column joint is one of failure zone. During earthquake large forces are applied on the Structure which leads to failure of the beam-column joint. Many researchers have done research on joints using different techniques, materials and introduced many repairing methods to enhance the resisting capacity of joints. From literature, it has been observed that glass fibres have enhanced many desirable properties of concrete. Hence, the fibrous material can be introduced in these joints to enhance joint property. The use of fibre reinforced polymer for structural strengthening and rehabilitation is becoming more popular due to its high strength to weight ratio, good fatigue life, good corrosion resistance and low maintenance cost. The fibre reinforced polymer laminates are introduced to enhance the flexural capacity and ductility. The addition of randomly distributed discrete fibres to the structural concrete increases its stiffness, ductility and load carrying capacity with reduced cracks. Fibres are effective in arresting both micro and macro cracks. In this study, we are going to prepare a glass fibre reinforced laminate and cure it for 18 hours, then it can be divided into small parts and added with concrete to increase the flexural capacity of beams. An experimental investigation is carried out on a concrete containing GFRP laminated parts in the certain range by weight of concrete. Material was produced, tested and compared with conventional concrete in terms of workability and strength. The present experimental investigation deals with the comparison study of fibre reinforced concrete with the conventional concrete. Here the cyclic loading is carried out to know about the load deformation characteristics of the specimen and also the other parameters such as ductility and energy absorption capacity are investigated.
