In the seismic risk management for enterprises, risk control measures such as an increment of seismic capacity, are essential, since they reduce both direct losses and recovery costs. On the other hand, risk control measures require the costs for implementation, so that the adequacy of the measure must be examined from the viewpoint of the accountability. Therefore, when considering the risk management of portfolio of buildings, the methodology to determine the seismic performance of each building consisting of the portfolio is required in order to utilize the cost beneficial counter measure. In this paper, proposed is the methodology to determine the optimal seismic performance of buildings based on the contribution to the portfolio loss. The efficiency of the proposed methodology is also demonstrated using the model portfolio consisting of 20 buildings in Kanto district.
