It is investigated that influence of rotational foundation input motion due to Rayleigh wave on the transfer function estimation of low-rise R. C. buildings. The discussion is based on the vibration tests on four low-rise R.C. buildings that have same foundation type, shape of plan and structural condition with different height. Microtremor observation was made with and without traffic vibration. Earthquake response is also observed and compared with microtremor case. The result shows that the transfer function estimation of low-rise R.C. buildings is affected by the rotational foundation input motion due to Rayleigh wave. The general feature observed of transfer function is confirmed by sway-rocking model subjected to Rayleigh wave.
