Abstract Economical constraints on the design of bridges usually necessitate the use of as few girders as possible across the bridge width. The girders are typically uniformly spaced transversely with the deck extending past the fascia girders, thereby resulting in an overhang. While designers commonly employ rules of thumb with regard to the geometry of the overhang, these rules of thumb generally address only the deck in-service strength and deflection requirements, and the effect due to construction load is not considered. In particular, the impact of the overhang on fascia girder behavior during construction is not well understood.

Fourth Edition - SEPTEMBER 2014 Price 80/- Printed by S.K. Enterprises Mumbai ii Preface to the Fourth Edition The book ‘Bridge Inspection and Maintenance’ had been an useful guide to the Engineers of Indian Railways. The First edition was published in August 1988 and was very popular among the field engineers. The Third revised edition was published in December 2005. The fourth revised and enlarged edition has now been brought out to fulfill the continuous demand for the book. The content of the book is throughout supplemented with several photographs to illustrate the real life situation so as to improve the understanding of textural material. While revising, latest correction slips and recommendations of bridge standard committee were also considered. The very first chapter has been revised duly incorporating the latest technique of mobile bridge inspection unit, necessity for submission of detailed documentation on newly constructed bridges etc. The chapter on detailed inspection of bridges is also supplements with numerous photographs. The portion pertaining to bearing is revised duly including the guidelines for maintenance in this chapter as well as chapter eight on maintenance of steel girder bridges. In the chapter on NDT of bridges, new NDT test of endoscopy technique and boroscope has also been added. In the chapter six on maintenance of bridges items pertaining to maintenance of composite girders are added. iii It is hoped that this book will fulfill the need and assist to field engineers in briefing them about the aspects to be inspected and the corrective action to be taken.
