Control of Crack Width in Deep Reinforced Concrete BEAMS
The cracking behavior of deep reinforced concrete beams is analyzed with attention focused on the amount of horizontal web reinforcement required to control the cracking in the web. A model to calculate steel stresses and crack spacing, which is also applicable to tensile members provided with reinforcement located at the side faces, is presented. For the latter type of elements a relation between the minimum reinforcement and the cracking behavior are reviewed and thick tensile members with reinforcement concentrated at two opposite side faces are discussed. Results from surveying calculations performed with the finite element program DIANA are presented and give close agreement with experimental observations presented. A 'beam model' specially suited for analysis of the overall structural behavior of deep beams is introduced. Results are presented by design curves for use in engineering practice. Examples of their use are explained in a reinforced T beam and a thick-tensile member with reinforcement placed at two opposite side faces. Both phenomena are defined by the behavior of the reinforced zones.
