ANALYSES OF BONDED, RING-SEPARATED AND STRENGTHENED MASONRY ARCH BRIDGES

The European Commission Directive 96/58/EEC, which seeks to harmonise transport policy with regard to heavy traffic, has resulted in the introduction, since January 1999, of the 40 tonne lorry on British roads. This has meant that many highway arch bridges require weight restriction, interim measures, strengthening or replacement. Three arches that had been load tested to failure at the Transport Research Laboratory (TRL) were modelled using finite element (FE) analyses. The first arch modelled was fully bonded, the second ring-separated and the third ring-separated and strengthened. All models were three-ring-brick arches. The development of the two-dimensional FE models and the analyses carried out using the test data to calibrate analytical models are described. A good correlation was obtained between the tested arches and the FE models developed. For the covering abstract see ITRD E106406.
