Recently, the construction demand for large underground space has been in creased so that the excavation technology for underground construction of building has been being developed. The construction of sheeting pile is for resisting the lateral pressure of soil during the excavation. In general, conventional sheeting H-pile is often used as a temporary member installed upon construction of outer retaining wall at basement floor. In CBW (Composite Basement Wall), R/C basement wall is combined with H-Pile and resists lateral soil pressure together. In this study, a total of five specimens with simple-ends were tested. Main parameters were the depth of basement wall and arrangement of shear connectors. The purpose of this experiment is to evaluate the flexural capacity to offer the raw-data of composite basement wall.

The purpose of this paper is to study retrofit methods for improving the flexural capacity of RC shear wall. Four RC shear wall specimens are designed and strengthened by using reinforcement or steel plate. Cyclic loads are applied to the specimen under constant axial force. Test result shows that the strength and ductility of specimen is improved when it is strengthened using reinforcement or steel plate. The specimen retrofitted by using steel plate shows high ductility. However the strength contribution of one is not much. It is shown that the most effective method is both to install the additional flexural reinforcement and to confine the ends of wall.
