The present paper discuses on a ductility factor of braces installed in the longitudinal direction of school sport halls. Based on the result of the elasto-plasitc dynamic analysis depending on varying input levels, the ductility index and the seismic index are re-studied. As numerical parameters, yield shear coefficient of braces on substructure, capacity limit deformation of braces and types of ground site are considered, and their effects on the ductility index are investigated. Furthermore, the method of estimation for demand strength of braces corresponding to demand seismic capacity is proposed considering dispersion of the ductility index by phase characteristics of input ground motions.
