[摘要] 本文對(duì)上海海事大學(xué)體育中心的四個(gè)體育館和一個(gè)體育場(chǎng)進(jìn)行了數(shù)值風(fēng)洞分析，計(jì)算出雙向曲面網(wǎng)殼屋面各風(fēng)向下的體型系數(shù)，并與我國(guó)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(shí)也給出了懸挑單曲屋面的體型系數(shù)。由于目前我國(guó)荷載規(guī)范無相應(yīng)的體型系數(shù)，上述規(guī)律和建議值可以為類似工程的設(shè)計(jì)提供很好的參考。

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
