 Antiqued High Rising Towers in Mountainous Terrain

doi:10.16183/j.cnki.jsjtu.2019.07.004

Abstract

Abstract: Taking the antiqued high-rising towers under terrain as the research object, wind pressure distribution and wind field around the tower are analyzed by using the method of computational fluid dynamics and RNG (Renormalization Group) k-ε turbulence model. The influence on wind pressure and wind field related to building height, the distance from hillside to the towers and the kinds of terrain are analyzed as well. The results show that the wind pressure distribution varies under different undulating terrain. The absolute value of the wind pressure on the tower surface increases with the building height, however decreases against the distance from hillside to the towers. In addition, parameters such as undulating terrain configuration have greater influence on the surface wind pressure of upper tower than the bottom tower.

Key words: antiqued tower buildings; mountainous terrain; wind pressure; wind flow
