The Experimental Study on Pull-out effct of Rebars embedded in Massive Concrete

매시브한 콘크리트에 매설된 철근의 Pull-out 거동

The seismic performance of bridge piers is evaluated in general by displacement terms, which are yielded not only by the member deformation but also by the pull-out of longitudinal bars embedded into foundation concrete. It is, therefore, important to understand the characteristic of pull-out effect in the view of seismic performance. In this study the specimens with different material strengths and diameters of re-bar were tested and the stree-slip were reported.
