Abstract
This study performed on composited beam using normal concrete joined cement-based strain-hardening composite (CSHC). The bending resistances of composited beams are provided with a new approach as follows: CSHC is placed in extreme compressive zone at top of simple beam whereas normal concrete is placed in the lower part of beam. The models and equations are suggested for various cases of steel reinforcing bar to useful predict bending resistance of beam. Also, an experimental program is conducted to generally evaluate bending resistance of the investigated beams. The moment capacity and stiffness of the composited beam are clearly improved with the increase of CSHC thickness.
