Many reinforced concrete pilotis buildings have been constructed in recent years. In case of pilotis buildings, stiffness and bearing strength capacity of the first story should be less than those of upper stories as the first story has not any bearing wall (aseismic wall). On the other hand, many earthquake disaster reports have pointed out that a degree of earthquake damage depends strongly on the amount of aseismic walls. Consequently, unless sufficient ductility is provided, the first story of pilotis building can be considered to suffer destructive damages during a strong motion earthquake. And to avoid serious failure to ultimate collupse, sufficient ductility capacity should be required for columns of the first story. However, the amount of required ductility may not have been made obvious up to now. The main purpose of this paper is to obtain a rough estimate of maximum displacements at the first story of RC pilotis building when subjected to strong motion earthquakes. Although the structural models for response calculations may be rather simple, the restoring force characteristics model of the first story is devised to express the peculiar aspects of reinforced concrete columns on referring to the experimental test reports published by BUILDING RESEARCH INSTITUTE, MINISTRY OF CONSTRUCTION. As a conclusion of this paper drawn from numerical calculations, not so many as fully satisfaction, we can infer that the maximum displacements of the first story of RC pilotis buildings, subjected to ground motions of 300〜500gal maximum, will be not less than 50×10^<-3> radian. In some cases, this maximum response value can be estimated roughly to be more than 80×l0^<-3> radian, while the response behaviour depends on how the parameters on SKELETON CURVE are to be chosen.
