摘要：
Large-span cantilevered roofs are wind sensitive structures, this paper presents the finding of large eddy simulation(LES) of turbulent wind field around large-span cantilevered roofs with grandstand in atmosphere boundary layer. For a typical horizontal cantilevered roof, the wind pressure is researched in fluid mechanic view, the large scales of wind motion are computed explicitly while the small scales are modeled by LES, the contours of wind pressure and velocity are present to reveal the coherent structures. Some general issues related to LES in wind engineering are discussed also.
