This paper presents the detailed work of the optimality criterion method of energy distribution for seismic structural design with frequency constraints. A typical numerical example is provided from which the pitfalls of the method for certain types of structures are explored. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
