Abstract As of 2005 in Japan, the number of tall buildings may have exceeded 2000. As building heights increase, lateral wind forces increase relative to lateral earthquake forces and become dominant. Serviceability criteria have also become an important issue in the design of tall buildings. Using information available from summarized design documents, response accelerations have been estimated using the equations prescribed in the Architectural Institute of Japan (AIJ), and the response accelerations compared with the guideline values for habitability to building vibration also prescribed in AIJ. For buildings with damping devices, a threefold increase in damping ratio was obtained from results of field measurements and full‐scale experiments. Acceleration ratios were calculated and plotted for various sectional shapes, frequency ratios and side ratios. Lastly, comparison is made between across‐wind accelerations with wind applied to the short side of the building and along‐wind accelerations with wind applied to the long side.
