STRENGTHENING A FIFTY-YEAR-OLD VIADUCT

The strengthening of a nine-span, 50-year-old reinforced concrete viaduct on a British industrial railway to handle heavier cars first involved a survey of the structure because no drawings were available. Since details of the reinforcement were not known, it was not possible to calculate the ability of the structure to take increased loading. Consultants recommended the application of stressed alloy-steel tendons to the lower edges of each beam with these members subsequently being gunited in place. Stresses in reinforcements and concrete under new loadings are less that those in the original structure under the lower loadings.
