| 摘 要： | 提出一种新的造型方法,通过改变网壳围护结构形状而改善其表面静风压力分布.应用有限元软件仿真,通过流—固单项耦合（FSI）计算了单层球面网壳围护结构表面的静风压力,并且初步探讨了风压的改变对主结构应力的影响.结果表明,改造方案将静风压力危险区的面积减少了48.8%.这种造型方法对研究改善其它形式结构表面静风压力的分布具有启发意义.

| Abstract: | To change the shape of envelope structures in shells,a modeling method is presented to improve the distribution of the surface static wind pressure(SSWP).The finite element software has been employed to carry out the SSWP calculation via FSI,in which a single-layer spherical shell is introduced as the target for wind loads,and the influence caused by the method to the stress on the frame structure has been taken into account as well.The result indicates that Remodeling-Program has decreased the area of SSWP-danger-zone by 48.8%.This method is also instructive for studying the improvement of SSWP distribution in other structures. |
