More About This Title Fundamentals of Seismic Loading on Structures
English
Fundamentals of Seismic Loading on Structures is organised into four major sections: introduction to earthquakes and related engineering problems, analysis, seismic loading, and design concepts.
- From a practical perspective, reviews linear and non-linear behaviour, introduces concepts of uniform hazard spectra, discusses loading provisions in design codes and examines soil-structure interaction issues, allowing the reader to quickly identify and implement information in a working environment.
- Discusses probabilistic methods that are widely employed in the assessment of seismic hazard, illustrating the use of Monte Carlo simulation with a number of worked examples.
- Summarises the latest developments in the field such as performance-based seismic engineering and advances in liquefaction research.
“There are many books on earthquake engineering, but few are of direct use to the practising structural designer. This one, however, offers a new perspective, putting emphasis on the practical aspects of quantifying seismic loading, and explaining the importance of geotechnical effects during a major seismic event in readily understandable terms. The author has succeeded in marrying important seismological considerations with structural engineering practice, and this long-awaited book will find ready acceptance in the profession.”
