COMPUTER-AIDED SKETCHING OF LOAD PATHS: AN APPROACH TO THE ANALYSIS OF MULTI-SPAN ARCH BRIDGES. BRIDGE MANAGEMENT. INSPECTION, MAINTENANCE, ASSESSMENT AND REPAIR. PAPERS PRESENTED AT THE FIRST INTERNATIONAL CONFERENCE ON BRIDGE MANAGEMENT, UNIVERSITY OF SURREY, GUILDFORD, MARCH 28-30, 1990

Single-span masonry arches are notionally three times redundant. This neglects the fact that the abutments are not rigid, so the degree of redundancy is actually greater. In multi-span bridges the problem is compounded. Direct analytical techniques based on a study of deformation are of limited value in these circumstances. Arches naturally release their redundancy by pushing the abutments outwards. They become three hinge structures. This approach does not allow closed solutions to the problem but rather indicates limits to the engineer's knowledge and understanding of the structure. Some details of the approach are described, using Robert Stephenson's Royal Border Bridge at Berwick-upon-Tweed as an example.(A) For the covering abstract of the conference see IRRD 830553.
