Subjectconcrete construction; causes of failures; collapse; errors
AbstractOne hundred and eighty-eight cases of errors in concrete structures, 29 of which resulted in collapse and 118 in distress, deterioration, excessive cracking, spalling, deflection or settlement, were collected from consulting engineers and government departments across Canada as part of a larger survey of the American Concrete Institute. The Canadian survey indicated that about half the errors originated in the design and the other half were due to faulty construction. Most of the collapses occurred during construction, mainly as a result of inadequate formwork or temporary bracing. A number of collapses were due to detailing errors in design. Most serviceability failures, on the other hand, occurred during use, many of which were due to a lack of consideration in design of serviceability problems or of the effects of temperature, shrinkage and creep.
