AU - Militano, C. AU - Rizkalla, S. T2 - Canadian Journal of Civil Engineering AB - The Disraeli facility, which was completed in 1960, consists of several overpasses utilizing rolled steel beam construction and a riveted steel plate girder bridge crossing the Red River in Winnipeg, Manitoba. The total length of the facility is approximately 707 m (2320 ft). In 1984, the City of Winnipeg commissioned Reid Crowther and Partners Limited to perform a load test on the facility to ascertain the possibility of increasing the maximum gross vehicle weight limit. The tests were performed on three consecutive Sundays, from September 23 to October 7, 1984.Three spans were tested. One normal and one skewed span were selected for the overpasses to study possible differences in their behavior along the exterior span of a three-span continuous riveted plate girder bridge over the Red River. The test was designed to determine the structural response of the bridges at different load levels, to determine the load distribution characteristics, and to investigate dynamic impact values for the test vehicles.This paper describes the instrumentation layout, data acquisition system, test vehicles, and testing procedures. Test results and comparisons with the predicted values utilizing conventional analysis are included. DA - 1987/2/1/ PY - 1987/2/1/ DO - 10.1139/l87-013 VL - 14 IS - 1 SP - 103-110 J2 - Can. J. Civ.

AU - Del Frate, R. AU - Rizkalla, S. T2 - International Journal of Pressure Vessels and Piping AB - Measurements of air leakage through cracks in specimens of reinforced concrete were analysed on the basis that the compressible flow occurred without heat transfer between the air and the concrete. The resultant friction coefficients were then correlated with the crack size and roughness parameters. The empirical relations were rearranged so that leakage rates could be predicted for a gas with known properties passing through cracks of known average dimensions. Checking the predicted leakage against the measured leakage rates gave agreement within ±35%, the scatter being attributable to the very irregular nature of cracks. The method presented for the prediction of leakage can be used with confidence for typical cracks in reinforced concrete containment vessels.

AU - Rizkalla, S. AU - Kwok, R. T2 - Batiment International, Building Research and Practice AB - A research study of damage to houses in Winnipeg, Canada, revealed that 94 percent had suffered some distress from shifting of the shallow‐footings foundations; the houses are of the typical Canadian pattern with basement areas. Discussed here are the details of the design study, with cost analyses, of five main foundation methods; the ‘best buy’, it is concluded, would be an optimised pile system, with basement walls designed as grade beams, supporting a timber main floor.

Gas production and composition were monitored for two years. The addition of old, anaerobically degraded refuse as a seed of anaerobic bacteria and the neutralization of the refuse were the two techniques which stimulated methane production. Yields of 80–150 l of methane per kilogram of dry, grindable, volatile solids were measured. The addition of anaerobic sewage sludge, acetate, and the initial removal of oxygen from a drum, were not stimulatory. Initially, it was the development of the methanogen population and not polymer hydrolysis which limited methane production.
