This text provides a concise reference source on seismic loading, design and analysis for postgraduate students, researchers and practising engineers, allowing the reader to quickly translate and implement research findings in a working environment. Throughout the text, the author has set out information about the design process and associated mathematics in an accessible format, always backing this up with worked out examples from actual research projects. The book opens with a comprehensive introduction to earthquakes and related engineering problems, including seismic waves, focus and epicentre and base line correction.
