Flexural Behavior of Prestressed Concrete Composite Tee-beamsU.S. National Bureau of Standards, 1970 - 12 pages Prestressed Tee-beams constructed by the split-beam method were tested to failure in flexure to study the behavior and ultimate strength of these beams and to compare their flexural characteristics with those of prestressed beams of conventional construction. Results showed that composite split-beams behaved similarly to the monolithically constructed beams on the basis of flexural response and ultimate load. |
