The IAStructE – IIIT Hyderabad student chapter of the Earthquake Engineering Research Centre organized an online Guest Lecture on 25th January 2024. The lecture was delivered by Dr. Mitesh Surana, Assistant Professor, Department of Civil Engineering, Indian Institute of Technology Ropar. The title of the talk was “Earthquake Performance Assessment of Buildings: Non-Linear Static Analysis”. More than 130 participants (from India and abroad), including PG and doctoral students, structural engineers, industry people, and faculty members, attended the lecture.

Dr. Surana provided a pivotal overview of Structural Analysis, explicitly focusing on the assumptions on the behaviour of structures or materials considering (a) Linear / Non-Linear Analysis; and (b) Elastic / In-Elastic Analysis. He delved into the primary concept of seismic analysis, focusing on the basic methods available for analyzing the responses of a structure when subjected to earthquake ground motion. Further, he explained the force-based seismic design, describing its design parameters and highlighting the structure’s behavior under earthquakes. During his presentation, he also summarized the main objective of seismic design and the intent of the code. The presentation involved a comprehensive valuation of non-linear static analysis annotating its capacity spectrum and capacity curve parameters. He also explained the estimation of seismic demand and earthquake performance assessment and highlighted their key features with related curves and results to provide the attendees with a clearer understanding of the topic and its practical applications. To conclude the presentation, Dr. Surana provided clear insights into the non-linear static analysis for the performance-based seismic design. The event was completed with an engaging and insightful discussion, with active participation from the attendees, which enriched the overall exploration of the topic and its significance in the field of earthquake engineering.
