In recent years, two seismic reinforcement methods of the construction that fill up the concrete and add the steel reinforcing material inside the steel cylinder peer are general. The ductility of the structure is improved by their reinforcements. However, the horizontal ultimate strength increases at the same time. It becomes very likely that the damage occurs for the anchor under the ground and the base section. They are difficult to retrofit. It's necessary not only to control the increase of the horizontal ultimate strength, but also to improve the ductility in the method of the construction. In this study, the main purpose is confirming the seismic reinforcement effect statically and seismically about seismic reinforcement method suggested by our laboratory. And it shows the effective seismic reinforcement method of the cylinder steel peer by the FEM.
