In the reinforced concrete buildings, it is important to prevent the columns from shear failure and improve the seismic performance of the columns. It is well known that the shear reinforcement is effective to improve the behavior of the reinforced concrete column by confining the core concrete of the columns. In this paper the authors present a new concept to improve the performance of columns subjected to large displacements in the inelastic range. To lead transverse cracks prevent slant cracks caused the shear failure. In order to verify the adequacy of this concept two tests are conducted, one is the cyclic shear bending test and the other is the monotonic compression test. The following findings can be obtained. 1) The cyclic loading performance of this new R/C columns can be improved much by inserting steel plates. 2) By inserting steel plates the monotonic loading performance can be also improved. 3) These effectiveness are brought by separating concrete section and steel plates reinforcement. 4) Various method is existent to improve the seismic performance of R/C column.
