Habitabilities of tall or slender buildings under winds and earthquakes are managed to be ensured by several technical methods. Hybrid mass dampers (HMD), one of the active-control systems, are gradually used in Japan. A 9-story slender building, whose height/depth ratio is 7.55, was planned to install the HMD to improve the habitability in wind excitations. The building is constructed at the area where same height buildings stand close each other, in Tokyo. In this study, the responses of the building are examined under several surrounding conditions through wind tunnel tests. A l/200 scaled building model is used for measuring wind pressures. The tests results shows that higher frequency components of the wind pressure on the model with surrounding buildings arc almost same or sometimes even increased comparing with results without surrounding buildings, while average pressure on the model is obviously decreased. To conclude, the accelerations of the building, which influence the habitability, induced by winds are not apt to be decreased even under such a densely surrounding condition. ƒL[ƒ[ƒhi‰pjF wind pressure test, habitability, slender building, hybrid mass damper. ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
