Artificial Intelligence Techniques for Bridge Reliability Assessment

Bridge safety is receiving more attention when some §bridges lost their function in recent years. Are the §bridges in service today still safe as they approach §their designed service life? Will a bridge built §today be able to safely carry traffic loads for its §intended 75-year service life? This book answers §such questions by developing Artificial intelligence §techniques for bridge reliability assessment. §§The techniques presented include new analysis models §of highway bridges, a new Shredding Genetic §algorithm (SGA) that is efficient to identify §dominant failure, and a new solver to improve the §efficiency of nonlinear analysis. These techniques §can be used to analyze the reliability of a §structure that could not be analyzed by traditional §methods. Plenty of on-site and full-scale bridge §experiments are introduced to form a solid benchmark §for bridge nonlinear analysis. Computer simulations §of these experiments demonstrate the efficiency and §applicability of the proposed algorithms. This book §should be helpful in bridge design and research for §large and complex systems, and can be used in the §safety evaluation of the bridges in service.
