Abstract - This meticulous study delves into how a G+14
factors like the intensity of building shaking during earthquakes and exploring improved design methods for overall safety. Considering different levels of shaking during an earthquake, the new guidelines in IS 1893 Part1(2023) provide a precise framework for understanding and calculating seismic forces. Comparing these guidelines with the 2016 ones is akin to examining two sets of instructions for building safety during earthquakes. The investigation seeks to determine if the changes in the new guidelines offer superior strategies for building resilience
building responds to earthquakes, utilizing the recently introduced guidelines in IS 1893 Part-1(2023). The focus is on understanding the spectral acceleration response, shedding light on the structure's behavior during seismic events. At its core, the research thoroughly compares these findings with the earlier IS 1893 Part-1(2016), aiming to pinpoint changes in seismic design principles that could impact the building's safety and structural integrity. By exploring shifts in fundamental periods, modal participation factors, and damping ratios, the study provides valuable insights into the evolution of seismic design standards. This exploration illuminates how these standards have adapted over time to enhance buildings' resilience against seismic events. In essence, this comparative approach significantly contributes to comprehending the effectiveness and implications of the updated provisions in the new draft of IS 1893 Part-1(2023). It offers a nuanced understanding of the evolution of seismic design, ultimately strengthening our ability to ensure the safety and stability of structures in the face of seismic challenges.

This study delves into understanding how a G+14 building responds to earthquakes, utilizing the latest draft rules from IS 1893 Part-1(2023) to assess seismic forces. A key objective is comparing these new rules with the older ones from IS 1893 Part-1(2016) to identify crucial changes in designing earthquake-resistant buildings. The focus includes observing the building's movements during earthquakes, especially relevant for tall structures. The research aims to enhance our knowledge of constructing robust and secure buildings in earthquake-prone regions. In simpler terms, imagine constructing a G+14 structure, ensuring it can safely withstand earthquakes. Government guidelines (IS 1893) were recently updated in 2023, forming the basis of our study. Beyond just understanding how the building performs under the latest rules, we're also comparing with the 2016 guidelines to determine if the updates contribute to building safety. We're evaluating
