Seismic effectiveness of retrofitting techniques for RC framed structure

Abstract

Many potentially devastating earthquakes have been allowed to occur in India. The Indian subcontinent suffered a devastating earthquake. The resulting human and material costs are enormous. The Bhuj earthquake hit Gujarat around 8:40 a.m. on January 26th, 2001. A lot of things have changed after the earthquake. India’s seismic regulations. There is a great need to evaluate the seismic performance of existing RC frame buildings, many of which were designed for a different load, and to retrofit them as necessary to increase their strength against earthquake forces, given what is known about the causes of past earthquakes and the likelihood that similar events will occur in the future. As we saw in the Bhuj Earthquake of 2001, open ground storey frame structures are especially vulnerable to the destructive forces of earthquakes, making it imperative that the ground story be fortified against massive deformation. The first floor of this G+3 building in Seismic Zone 4 has been retrofitted using three different methods. Here is a list of them: jacketing for the basement’s concrete slab. Filler wall made of reinforced concrete. Iron Reinforcement. Therefore, the primary goal of this research is to determine the efficacy of various retrofitting strategies with respect to reducing seismic risk.
