Performance of Infill Walls as a Global Retrofitting Technique

Considering the recent growth in the field of infrastructure development in India, many towns are getting upgraded into smarter cities. The challenge before the planer to set a well planed city is to overcome the problem related to parking that arises due to increasing number of vehicular traffic.In many cities it has been observed that the residential parking space is provided in the building itself by utilizing open ground storey. Past earthquakes have demonstrated the vulnerability of such kind of structures. Infill walls act as a lateral force resisting element for high rise structures. But less amount of research is dedicated to understand the behaviour of infill wall as a retrofitting method. Hence, the objective of this paper is to assess the potential of global retrofitting technique i.e. incorporation of infill walls in the open ground storey. For this purpose three dimensional models are adopted to understand the effect of infill wall. Comparative results are presented in graphical form to justify the chosen global retrofitting technique.
