It is evident that due to rapid growth in population tall buildings are being raised in urban areas. The factors which mainly determines the need for tall buildings are limited space and significant cost of land in developing countries like India. In general, the tall buildings are of symmetric and regular in plan. These days tall buildings with different plan and shapes are being regarded and hence irregular plan shapes are also in place in the architectural design. The main objective of this paper is to study and analyze a tall building model of 232m (full height) subjected to different wind pressure and to measure its acceleration using ADLX-335 sensors to the applied wind load on various models on a 1:500 scale with conventional plan rectangular shape under isolated condition. to evaluate pressure co-efficient. This study is being conducted on a low-speed subsonic wind tunnel set up. The building model is of 10cmx20cmx47cm (lxbxh) The said test was conducted on three different models viz., Control Model, Wood Framed model, and Wood-Steel model. The pressure co-efficient are measured along 0-, 90- and 45-degrees angle of wind attack. Further, based on the variation of mean pressure co-efficient, critical angle of wind incidence and corresponding accelerations have been identified. The wind speed replicated different wind velocities for cities mentioned in IS 375 Part III The results showed that solid acrylic model showed considerably high vibration whereas due to low circumferential surface area wood framed and wood with steel ties showed low vibration levels.
