［摘要］基于CFX10-0軟件，采用SST k-ω湍流物理模型，對(duì)閩南某大跨體育場(chǎng)館屋蓋結(jié)構(gòu)的風(fēng)荷載進(jìn)行數(shù)值模擬，并將計(jì)算結(jié)果與風(fēng)洞試驗(yàn)數(shù)據(jù)進(jìn)行了對(duì)比，對(duì)比結(jié)果顯示兩者基本吻合，說明了數(shù)值模擬在大跨建筑群屋蓋結(jié)構(gòu)應(yīng)用中的可行性；探討不同相對(duì)位置風(fēng)干擾效應(yīng)對(duì)一場(chǎng)一館大跨屋蓋風(fēng)荷載的影響，分析一場(chǎng)一館之間的風(fēng)致干擾機(jī)理，干擾體之間位置關(guān)系與形狀很大程度上影響了建筑物實(shí)際平均風(fēng)壓,干擾因子主要在-4～2之間分布。

Abstract:Based on CFX10-0 software and SST k-ω turbulence physical model, the wind load of a large-span stadium roof structure in southern Fujian was simulated numerically, and the results were compared with the wind tunnel test data. The comparison results show that the two are basically consistent, which shows the feasibility of numerical simulation in the application of large-span building group roof structure. In response to the influence of wind load on a large-span roof of one building, the mechanism of wind-induced interference between the stadium and gymnasium was analyzed. The location and shape of the interference bodies largely affect the actual average wind pressure of the building, and the interference factors mainly distribute between -4 and 2.

Keywords:large-span structure; numerical simulation; lift coefficient; interference effect
