| Abstract: | A new method for designing the interior and exterior cores of the steel fiber reinforced concrete(SFRC)unbonded partially prestressed flat beam and column joints. It was based on the test of four flat beam?column joints and the theoretical researches. The effects of the steel fiber mixed in the core concrete and the unbonded prestressed tendons placed in the flat beam were considered. The concrete strength of joints was fully used and the effects of axial loads in the columns and the flat beams were involved correctly in the new design method. Vertical shear resistance capability of the joints was also checked. The reliability of the proposed method is verified by the test data. |
| Keywords: | steel fiber reinforced concrete(SFRC) unbonded partially prestress flat beam?column joints |
