Abstract
The purpose of this report is the presentation of model when the performance based structural design is applied to the actual building. Authors participate in "MARUNOUCHI BUILDING" design team and are trying the performance based structural design. It is significant that the practical structural designer's point of view about the performance based structural design is informed, when the performance reguration of seismic criterion is established. The outline of the structural design for "MARUNOUCHI BUILDING" is described in this report.
