| Abstract | ||
| This paper aims mainly to study the effects of using steel fiber in reinforced concrete parts of composite structural elements, which consist of two main parts, the steel and concrete sections. Then to explain the effects of using the hooked ended steel fibers on the load-slip relationship between concrete and steel parts of composite structural elements. The standard push-out test is a convenient and the only available method to define this load-slip relation. There are five series of tests made on push – out test specimens prepared for this purpose. These tests are containing various percentages of steel fibers ( 0.0%, 0.5%, 1.0%, 1.5% and 2.0% ) by volume of concrete. The hooked ended steel fiber with aspect ratio 100 were used in reinforced concrete parts of composite structural elements, which consist of two main parts (the steel section and the concrete section). From the obtained results, an empirical non-linear equation was developed, to calculate the shear stiffness for connectors at any amount of slip. This will give information on the ultimate shear capacity of the shear connector, which were used in the composite structures and the corresponding load-slip relationship. | ||
