After the Pacific coast of Tohoku Earthquake in 2011, a provisional tsunami resistant design has been established for tsunami evacuation buildings. They are required to possess both seismic and tsunami resistant performance, to secure human lives from earthquake and tsunami disaster. In the present paper, relationships between the seismic and tsunami resistant designs for steel building frames are minutely investigated by simple plastic calculations using story-aggregation frame models. From observation of the parametric calculations, it has been clarified that the tsunami resistant performance is closely related to the seismi resistant performance and seismic retrofits for existing inadequate buildings have significant effects to improve the tsunami resistant performance.
