Short description
As an outgrowth of statistics and probability, Bayesian theory has been applied to numerous research areas, particularly, biology, medical sciences, physics, and information theory. More recently, the Bayesian approach has been introduced to address structural dynamics problems, including earthquake ground motion and the material properties of concrete, rock, and soil. This is the first book to address the applications of Bayesian methods to such challenging civil engineering problems as modal/model updating. Covering real-world case studies in civil engineering and beyond, the book presents methods applicable to mechanical and aerospace engineering and familiarizes readers with all the latest developments in the field.
