The paper discusses the seismic performance of a relatively small spatial structure such as school gymnasia subjected to earthquake motions. The method is based on a seismic risk analysis. First, an equivalent lumped mass model for evaluating the seismic responses of longitudinal direction simply is proposed, and the validity of the model is investigated. Second, a seismic risk and an expected loss of the structure are calculated based on the results of the elasto-plastic response analysis. Finally, the relation between the expected losses and yield base shear coefficients used for the substructures is examined, and the yield base shear coefficient is discussed in order to suppress the expected loss below to a certain threshold.
