Steel bridge strengthening : a study of assessment and strengthening experience and identification of solutions

The stresses imposed on UK roads by forty tonne vehicles have led to an extensive programme of bridge improvements across the country. This book draws on case studies to create an essential tool for all bridge engineers involved in strengthening steel bridges to meet these challenges. Resulting from the Highways Agency's assessment and strengthening of steel and steel/concrete composite bridges, this report disseminates the knowledge gained and ingenuity used during this work and will be an invaluable reference for future work. "Covering a wide range of structural elements and related defects, this collection of twenty concrete bridge strengthening and repair case studies showcases solutions to real problems encountered in the field and the processes by which those solutions were developed. Drawing on a lifetime of experience Atkins consultant Iain Kennedy Reid provides insight into methods of investigation and diagnosis of problems relating to beams, slabs, columns and panel walls, as well as how to apply demand-led research to these problems in a practical way."--Pub. desc The fully revised, restructured and updated second edition of the ICE Manual of Bridge Engineering has been written and edited by a team of leading experts and presents valuable contributions from across the field within a single resource. The second edition comprehensively addresses key topic within bridge engineering, from history and aesthetics to design, construction and maintenance issues. Content: Introduction and objectives Inspection and in-situ testing Reasons for strengthening Methods of a avoiding or limiting strengthening Factors to be considered when designing strengthening Methods of strengthening Parapet upgrading Bridge bashing Fatigue Identifying research Case histories Contractual experience Lessons learned for the future Conclusions References Index Addresses key topic within bridge engineering, from history and aesthetics to design, construction and maintenance issues. This book is suitable for practicing civil and structural engineers in consulting firms and government agencies, bridge contractors, research institutes, and universities and colleges. Covering a range of structural elements and related defects, this title includes a collection of twenty concrete bridge strengthening and repair case studies that showcase solutions to real problems encountered in the field and the processes by which those solutions were developed. This report explores work done by the Highways Agency in assessing and strengthening steel and steel/concrete composite bridges for 40 tonne lorries, and covers measures beyond the initial assessment to avoid or limit strengthening. It also identifies strengthening solutions.
