In low-rise or medium height RC buildings such as school buildings, the spandrel walls are often monolithically cast together with column. This type of column behaves like a short column in which shear failure is likely to happen. At present, in one of the important earthquake resistant design method, the spandrel walls are considered separate from columns by setting slit. As a result, the ductile flexural behavior may be expected because the shear span to depth ratio of the column becomes more longer. In this paper, two seismic retrofit design methods for RC column with spandrel walls are proposed without considering slit in design. In one method, only the ductility and in the other method, both the ductility and the lateral capacity of the column with spandrel walls utilizing high strength steel bars for prestressing and steel plates can be improved.
