内容記述 | Static and dynamic interference tests are performed by a series of wind tunnel tests to examine the existence and characteristics of wind-over-top (WOT) flow among high-rise buildings. A rigid-aerodynamic model or a principal model is a square cylinder with pressure taps and pivots on the elastic system. A value of pressure at each pressure tap and displacements at top of the principal model are measured for different wind velocities and directions. Two types of wooden rigid interference models in different heights with the principal model are put in different positions in the Cartesian axis. The experimental results showed that the WOT flow effects to a large area on the sides of the principal model in terms of the static pressures. A part of the front face of the principal model could increase by 46% mean pressure coefficient due to the presence of the WOT flow. Moreover, the WOT flow contribute the beneficial effects in term of dynamic structural design. In a close distance of two models, the WOT flow makes vortex-induced vibration of the principal model vibrate with small amplitude. In the larger distance, the WOT flow makes the principal model vibrate at high reduced velocity. | |||||
