Title: Cyclic loading on recycled aggregate fiber reinforced concrete beam-column joint 

Fund: 2,53,295/- 

Objectives:  

1. To investigate the displacement, hysteresis loop, stiffness, and energy dissipation of beam- column joint. 

2. To analyze the effect of different types of fiber with recycled aggregate on beam-column joint 

Expected Outcomes:  

This research work is expected to yield the basic behavior of beam-column joint under cyclic loading and evaluate the feasibility of adopting GI fiber and PP fiber while using recycled aggregate. Thus, the enhancement of joints during seismic events can be presented in an environment friendly and cost-effective way. A comparison between the performances of Gl fiber and PP fiber under cyclic load will also be evaluated. This research will help in incorporating the effect of recycled aggregate and fibers into the existing design guidelines. 

Hence the significance of this research can be summarized as following. 

1. Use of recycled aggregate results in poor mechanical and seismic behavior of concrete. The incorporation of short fibers will help to overcome the shortcomings of recycled aggregate and will also enhance the behavior of beam-column joint under cyclic loading. 

2. GI fiber is comparatively cheaper and have high tensile strength, great resistance to corrosion and chemical attacks which makes them, unlike steel and other fibers, suitable for structures subjected to aggressive environment.
