MODERN STUDIES IN EARTHQUAKE, STRUCTURAL, AND SOIL ENGINEERING

This book presents a collection of interdisciplinary studies addressing key challenges in structural engineering, geotechnical innovation, and environmental sustainability. The chapters collectively emphasize performance-based assessment, resilience, and the application of advanced analytical methods in engineering and development contexts. The first two chapters focus on structural systems and materials, examining the seismic performance of self-supporting structures in accordance with RPA2024 and Eurocode 8, as well as reviewing the critical factors affecting the behavior and performance of concrete-filled steel tube (CFST) structures. These contributions provide important insights for improving safety, reliability, and design efficiency in modern construction. The third chapter extends the discussion to climate adaptation in the agricultural sector, analyzing the role of irrigation facilities in mitigating the adverse impacts of climate change on agricultural productivity in south- western Nigeria. It highlights the importance of sustainable infrastructure in supporting food security and regional development. The final chapter introduces a data-driven approach to geotechnical engineering, combining experimental validation with a GA-optimized artificial neural network to predict the behavior of lime-stabilized expansive clay. This innovative methodology demonstrates the growing role of intelligent modeling techniques in advancing material characterization and engineering practice.
