The building-machine structure system is simulated by an idealized two-degrees-of-freedom system with small mass ratio, the response spectrum of the system is obtained by the analog computation. It can be seen that the coincidence of the periods of both systems has to be evaded from the view point of the design of the machine structure, and it is proposed that the two-degrees-of-freedom system can be examined easily through T_b-T_m response spectrum. The width of the two-degrees-of-freedom system around T_b=T_m is discussed to know the shape approximately of the peak of the spectrum. The response spectrum of a single-degree-of-freedom system to the acceleration recorded upon a building is computed. A statistical computation in case of the two-degrees-of-freedom system is performed and the result is compared with the response spectrum by the analog computation.
