It has been thought that the strength of columns with spandrel walls can be calculated by neglecting the effects of the walls where the thickness is less than 10cm and the thickness ratio is less than l/6. But it has been reported in some recent papers that the strength with spandrel walls is affected by the ratio of wall height to column height and the ratio of thickness of wall to that of column. The shear force, required to fracture framed walls may differ due to concrete compressive strength and due to reinforcing volume in the wall. As a column with spandrel walls is a kind of framed wall, structural elements of concrete compressive strength and reinforcing bar-volume have to be considered. Accordingly, the authors performed the experimental studies on the effect of above-mentioned structural elements on the strength of columns with spandrel walls. The results were as follows. 1. The strength of columns with spandrel walls must not be calculated by neglecting the effects of the walls where the thickness ratio is less than 1/6. 2. The reinforcing bar-volume in the wall and the transverse reinforcing bar-volume in the column have effects on the strength of column with spandrel walls.
