    Abstract: 現在建築物以跨徑大的為國家著名城市的象徵性建築物,所以球殼屋頂結構物的造型也越來越常出現,而且其特性也較輕較軟,因此在受風力時會有更明顯的受力特性存在,所以研究此類屋頂的風載重越顯重要。



    Now in order to span a large building known as the national symbol of urban buildings, the spherical shape of the roof structure appears more and more often, and its properties are less soft, so there will be more affected by wind there is obvious stress characteristics, the study of such roof wind load becomes more important.

    This paper discusses the roof for the shell, generally divided into the span of order of 50 meters, 100 meters, 150 meters and 200 meters, height divided by the ratio from 0.1 to 0.5 for 20 models. Structural analysis program operation can be found that span of 50 meters and 200 meters in height than in the 0.1 and 0.2 are significant differences. This article discusses the structural modal analysis, weight analysis to structure analysis by comparing the wind, and then choose from some of the more problematic of bars do.

    By this analysis that, when the smaller span structures such as 50 meters, and the greater span of 200 meters, for example, suffered after the axial force of the wind with the known long-span structures are different. Can verify this with the distinction between literature different long span structures.

    Because the pressure data is too small, in the course of the study results will be slight differences with the literature, so need to further research and discussion.
