Prof. Ratnesh Kumar, Department of Applied Mechanics, Visvesvaraya National Institute of Technology (VNIT), Nagpur gave an online guest lecture on Seismic Vulnerability and Risk Assessment: ML ApproachΒ on 29 August.Β The talk was forΒ postgraduate students, research scholars, structural engineers, industry professionals, and faculty members.
Prof. Ratnesh Kumar began his lecture by signifying the need to predict the earthquake behaviour of the structures, to enlighten the local bodies and the government to reduce the loss of economy and human lives in the near future. He shared quite an interesting point that structures act as a shield to protect humans from natural hazards like floods, cyclones, etc., but the same acts as killers in the case of earthquakes. The talk proceeded with the concept of seismic vulnerability and the different methods for its risk assessment. The lecture focused on understanding the seismic risks associated with different regions and the vulnerabilities present in various building types. The use of Machine Learning (ML) and Geographic Information System (GIS) software for risk assessment was clearly illustrated through a case study in Nagpur city using the Socio-Economic Cluster approach. Other assessment-aiding parameters such as identifying the performance point using the demand and capacity curves and types of mapping were discussed further. The talk also shed light on the challenges faced in risk assessment and construction practices. The lecture concluded by highlighting the potential of combining various models using ML and GIS techniques for improved accuracy. In the end, an engaging question and answer session took place between the attendees and the speaker, where the insightful discussion and clarifications provided further enrichment of the participantβs understanding of the topic.
