Document Type: Journal Paper

Abstract:

Method to predict fatigue strength based on failure envelope of materials involved; factors influencing fatigue strength, such as percentage of steel, level of prestress, and ratio of dead to live load; recommendations on notion of safety and on safety factors for concrete under fatigue loading.
