Introduction to Seismic Analysis of Structures

Earthquakes pose one of the greatest natural threats to our built environment, making seismic design an essential skill for modern civil and structural engineers. This text-based course guides you through the fundamental principles of structural dynamics and seismology without requiring advanced prior knowledge. You will learn how to evaluate how buildings and infrastructure respond to ground motion, ensuring safety and compliance with modern engineering standards. By completing this course, you will gain a clear, mathematical, and practical understanding of how to analyze structures under seismic loads. You will transition from basic theory to applying modern analytical methods used in engineering practice today. What you'll learn: - Understand the core principles of seismology, plate tectonics, and seismic wave propagation. - Analyze single-degree-of-freedom (SDOF) systems under dynamic loading conditions. - Calculate structural responses using response spectrum analysis and lateral force procedures. - Apply modern seismic design philosophy, including ductility, drift limits, and building code requirements. - Evaluate structural vulnerability and explore contemporary mitigation techniques like base isolation. This course begins with essential terminology, basic seismological concepts, and foundational dynamic equations before moving into practical analysis workflows. Through clear, step-by-step written explanations and worked mathematical examples, you will build a strong conceptual foundation in earthquake engineering. This course is designed for civil engineering students, practicing structural engineers looking to refresh their knowledge, and beginners interested in structural dynamics. No advanced background in earthquake engineering is required. Start reading today to master the fundamentals of seismic analysis and build safer structures.
