Preventing the Impact of Earthquakes on Multistorey Buildings by Solidification

Abstract

This study investigates how soil solidification and damping enhancement can effectively reduce the impact of earthquakes on multistorey buildings, particularly in seismically active regions such as India. By analyzing earthquake data from 2015-2025 and examining the structural vulnerabilities of common building types, the research highlights the critical need for improved foundation stability in weak or liquefaction-prone soils. Mathematical formulations of seismic loading, damping behavior and solidification processes are developed to model soil-structure interaction and evaluate vibration characteristics in a 10-storey shear building. Results show that increasing damping and soil stiffness significantly reduces displacement, resonance effects and inter-storey drifts, while solidification raises natural frequencies and improves energy dissipation at the foundation. The study establishes a quantitative relationship between seismic parameters and solidification time, demonstrating that higher vibration intensities delay solidification and increase porosity. Overall, the findings confirm that soil solidification combined with adequate damping and adherence to seismic design principles substantially enhances the safety, resilience and performance of multistorey buildings during earthquakes.
