This paper shows the characteristics of wind-induced accelerations of box-like high rise buildings obtained by the wind tunnel tests. For the model, the scaled model of an existing-building and parametrical arranged models are used. The test results of the scaled model are compared with ones of the full scale measurement. Furthermore a statistical estimation method for across-wind acceleration responses of box-like high rise buildings is shown. Main results are as follows. (1) Experimental results are close to the full scale ones. (2) Correlation between the along-wind acceleration and the across-wind one is poor. (3) Characteristics of fluctuation of the accelerations seem to be the narrow-band random process. (4) Standard deviations of the accelerations are in proportion to about 3 rd power of mean wind velocity. (5) Estimated accelerations by the suggested method are close to the experimental results and the full scale ones.
