(現(xiàn)代設計集團上海建筑設計研究院有限公司，上海200041)[摘要] 本文對上海海事大學體育中心的四個體育館和一個體育場進行了數(shù)值風洞分析，計算出雙向曲面網(wǎng)殼屋面各風向下的體型系數(shù)，并與我國現(xiàn)有荷載規(guī)范中單曲拱形屋面體型系數(shù)加以比較，總結(jié)出此類形狀屋面體型系數(shù)的分布規(guī)律，并給出了建議值；同時也給出了懸挑單曲屋面的體型系數(shù)。由于目前我國荷載規(guī)范無相應的體型系數(shù)，上述規(guī)律和建議值可以為類似工程的設計提供很好的參考。

( Xian Dai Architectural Design Group,Shanghai Institute of Architectural Design & Research Co. , Ltd., Shanghai 200041, China)Abstract: Numerical wind tunnels were carried out for Shanghai Maritime University's sports center which is including four gymnasiums and one Stadium. The figuration coefficients of double-curved-reticulated shells under every wind direction were obtained. We analyze the difference between figuration coefficient of single-curved roof in China Load Code and the above results. The distributing rules of figuration coefficients of curved-reticulated shells are summed up, and the proposed values are presented. The figuration coefficients of cantilever single-curved surface are also presented. Because there are not corresponding regulations about these shape roofs, the above distributing rules and proposed values are good reference for similar structural design.
Keywords: curved-reticulated shells; figuration coefficient; numerical wind tunnel
