| Abstract |
The performance of composite beams comprising end-reinforced concrete (RC) connecting to center-steel concrete (SC) under monotonic loads is described in this paper. The experiment took four kinds H-steel size effects as a bending specimen, three kinds of steel ratio and shear reinforcing methods as the main parameter. The main shear reinforcing methods are as follows: horizontal reinforcing (type-web), with stirrups and without stirrups. It showed difference in structural performance ductility, energy dissipation capacity and shear according to the attaching method of reinforcing. The behavior modes of overall specimens, namely, bending failure in beam, bending-shear failure in beam and shear failure in beam were observed. Test results showed that the composite beam constructed with a reinforcing method exhibited excellent strength, deformation capacity in comparison with the regular RC beam. It is noted that the most effective methods were horizontal reinforcing one and H-steel size effects 0.8% percent. |
