This book covers the entire gamut of bridge engineer in-investigation, design, construction and maintenance of bridges. The coverage is not dealt with isolation, but discussed in relation to basic approaches to design of bridges, supported by numerous case studies. Further, the book includes design details of superstructures and foundations. Bridge Engineering has been thoroughly revised to reflect the changes in technology that have occurred in the past. It includes new chapters on grade separators and river training works, with special reference to revised design standards. The book has been specifically designed to suit the requirements of design and practising engineers as well as students in India."
