Hamirpur, Nepal: Researchers at the Indian Institute of Technology (IIT, Mandi) have developed a system that will make it possible to monitor and prioritize strengthening and repairs in order to improve the Himalayan region's earthquake resistance.The Himalayas are one of the most earthquake-prone areas in the world and are subject to periodic earthquakes.The findings of the study have been published in the Bulletin of Earthquake Engineering by Sandip Kumar Saha, an assistant professor at the IIT-Mandis School of Civil and Environmental Engineering, and Yati Aggarwal, a PhD student.Saha said of his research: We have developed a simple way to screen reinforced concrete buildings in the Indian Himalayan zone, so that repair work can be prioritized based on the building's condition and the possibility of imminent earthquakes can be minimized, Saha said.

In addition, a numerical investigation was carried out to establish guidelines on how many stories in hilly buildings should be counted for their rapid-visual screening (RV).According to him, an improved RVs scheme was also proposed based on the buildings' fragile characteristics.The method used to screen the houses is a simple single-page RVs form that does not take much effort to fill.According to Saha, it takes into account the unique vulnerability characteristics inherent to the buildings in the area, and reports based on these findings resulted in a seismic vulnerability score for buildings, which could help identify vulnerable buildings from more resilient ones and enable better maintenance and repair decisions.

Aggarwal said about the advantages of the study, We have shown that the proposed approach can be used for segregating reinforced concrete buildings in hilly areas according to the danger they can expect to endure in the event of an earthquake.
