This paper discusses vibration characteristics of a reinforced concrete floor which has adjoining rooms. Floors, beams, and columns are respectively idealized by lattice beams, horizontal beams as including an effective width of floor, and vertical columns calculaterd as being fixed in space at their upper and lower floor positions. Natural vibration analyses of the structural models are carried out, assuming that masses are lumped on nodes. Frequences of a floor are shown to be changed by the influence of the adjoining-room floors, and thus multi-room floor calculation is recommended when exact frequencies are needed as in the case of investigation of resonance problems of precision instruments, etc. It is also shown that single-room floor calculation gives adequate safety margins as far as vibrations due to walking are concerned.
