FINITE ELEMENT MODELING OF CAMBER OF PRESTRESSED CONCRETE BEAMS

[摘要] For large-span reinforced concrete beam structures developed by the method of determining the camber due to the prestressing of a steel rope on the concrete. Performed numerical experiments to study the impact of various schemes layout prestressed reinforcement without bonding with concrete on the distribution of the relief efforts along the path of the reinforcement.
