Bill Harvey

Bill Harvey wanted to be a bridge engineer from the age of seven. He studied at Leeds and worked on a number of bridges, including Humber, before taking up an academic career in 1977. Since 1981 he has worked on arch bridges, with a broadening interest in historic structures generally. He set up his consultancy in 2000. Since then, his work has encompassed inspection, assessment,  monitoring and refurbishment of structures. He has written a guide to Arch Bridge Assessment for the International Federation of Railways (UIC) and numerous reports for Network Rail in the UK. Bill continues his research work. In 2006 he tested a full scale skew arch bridge and from that developed fresh concepts on arch behaviour leading to new analytical techniques. The measurement techniques used there were developed in monitoring bridges where it was necessary to measure movement under live traffic. He has also developed techniques for measuring movement where datums are difficult to provide. Bill has lectured widely in universities across Europe and further afield. He is deeply concerned about the lack of fundamental understanding of structural behaviour exhibited in much analytical work in the modern world.

Papers:

Paper 1: Monitoring and Measuring Historic Masonry Structures
Abstract: Monitoring masonry structures is fraught with even more difficulty than is found with more modern construction. Masonry is stiff and brittle, movements are small and finding reference points is often difficult. The paper discusses the problems in the context of three masonry bridges where behaviour was unsatisfactory but difficult to diagnose. The benefits of short term deflection measurements will be discussed and some measuring techniques presented. These include very simple deflection measurements set up to reveal patterns of response to normal traffic loads, optical techniques for displacement measurement in places where a local datum cannot be provided and the use of high sensitivity telltales for crack monitoring.

Paper 2: Interactive Analysis of Arching Masonry Structures
Abstract: In the modern world, it is often assumed that every structure can be analysed simply to provide thorough understanding of behaviour. Modern computer analyses, however, frequently yield results that are clearly in error, for example, indicating collapse of structures that are behaving well. The paper discusses a range of specific problems with historic masonry structures where expensive finite element (FE) analysis led to unacceptable results and much simpler interactive equilibrium studies showed the structure to be sound. The paper is illustrated with bespoke spreadsheet graphical analyses of specific complex vaulted and arching structures.
