Study on Concrete Beams Reinforced by Steel Wires

Abstract

Strengthening and energy saving is an important engineering of existing buildings. The test is preceded by using two groups of beams, during which the comparisons of cracking load，yield load and ultimate load are made between strengthened and un-strengthened beams. The test result shows that bending capacity of reinforced beams rose obviously. Finally, based on experimental study, the formula of ultimate bending capacity which can be used in engineering design is presented.
