Sustainable Bridges: Research Project of the European Community

<p>Vertical static load tests on sixteen 2,95m span multi-ring clay brick arches were carried out to investigate the effectiveness of retro-fitted steel reinforcement as a strengthening measure. The principal parameters investigated were the arch geometry; arch ring thickness; area and distribution of reinforcement; type of inter-ring shear reinforcement and mortar strength. In each case a full width line load was applied incrementally to the upper surface of the arch at quarter span until collapse occurred. In all cases, longitudinal reinforcement was found to delay the onset of cracking and to increase the load carrying capacity. Radial dowels were found to be the most effective means of preventing ring separation and the simplest and quickest to install. Longitudinal reinforcement was found to be the most effective when used with measures to prevent ring separation.</p>

<p>In the paper a proposal of the unified multi-level classification of bridge defects declining condition of bridges is presented as one of the most important elements of asset management. General scheme of bridge degradation process is described with classifications of basic mechanisms of bridge degradation as well as stimulators of degradation mechanisms. Criteria of defects classification are proposed taking into account effects of activities of bridge degradation mechanisms. The proposed general conception of classification methodology of bridge defects is addressed to all types of bridge structures and all types of structural materials. Examples of hierarchical three-level classifications of defects are presented for concrete, steel and masonry bridge structures.</p>
