The authors have carried out full-scale measurements on a high-rise building to obtain data for wind resistant design of claddings. Characteristics of mean wind-induced internal pressures were reported in the previous paper (Part1). The present paper describes the fluctuating wind-induced internal pressures measured on 17th Sep. 1995 and 22nd Sep.1996 when typhoons hit the Kanto area. There was a peak in the power spectral density of the fluctuating wind-induced internal pressures at lower frequency than that of the wind pressures measured at the top of the building. The power spectral density of wind-induced internal pressures decreased sharply over 0.06Hz because of the filter effects caused by leakage pass. The coefficients of fluctuating wind-induced internal pressures were about 0.05 and the peak coefficients were about -0.4. These values are smaller than ones recommended by A.I.J.
