Reinforcement method of reinforced concrete beam by using non-stressing strand

Abstract

Many methods can be used in the repair of bridges or other structural buildings. The aim is to increase the existing capacity. In the reinforced concrete beam structure, capacity of structural elements can be carried out by reinforcement method. The research was done by experimental loading test in laboratory. The test objects are consisted of 2 (two) reinforced concrete beams: a normal beam without reinforcement (NB) and a reinforcement beam by using non-stressing srand (RB1). The dimensions of the beams are 150mm x 300mm x 3200 mm. All beams are loaded by static-monotonic load until collapses. From the results of the research, the first yield load for the NB beam and RB1 beam respectively are 22 kN and 29kN. The deformations that occur at the conditions are 9.5mm and 14mm respectively. The collapse occurring on the NB beam is the bending collapse, whereas in the RB1 beam is a bending- shear collapse.
