Experimental Study on Axial Compressive Behaviors of Steel Recycled Concrete Composite Columns
In order to reveal the performance of steel recycled concrete composite columns, 6 specimens were designed for axial compression loading experiment. And two factors which are recycled coarse aggregate replacement percentage and slenderness ratio of column are taken into consideration. The bearing capacity and load-displacement curves of composite columns are obtained. Based on the test, the failure patterns and the influence of recycled coarse aggregate replacement percentage and slenderness ratio to axial compression load-bearing capacity are analyzed. In the end, the calculation formula for axial compression load of steel recycled concrete composite columns is presented.
