Deformation study on flat beam in steel fiber concrete

Based on the experiment upon 10 beams of steel fiber reinforced concrete, the article expounds on the force bearing capacity, deformation property and deflection calculation in the flat beam of steel fiber reinforced concrete and pinpoints that with a proper amount of steel fiber added in concrete beam, the structural property of the flat beam concrete has been improved, the entire beam's property and bending rigidity has been ameliorated, and deflection of the beam has been reduced. Also by the comparison between the beam's actual deflection values and calculation values, the article concludes that the actual deflection formula under the steel fiber concrete standards of (CECS38: 92) can be applied to the calculation of the flat beam deflection in steel fiber reinforced concrete.
