中文摘要：

对于玻璃钢烟囱的设计我们国家还没有相应的规范，只是参考钢烟囱、钢混烟囱以及砖石结构烟囱等设计方法。这些方法将玻璃钢烟囱视作各向同性的悬臂梁，无法表达复合材料结构的特点，因此具有很大的局限性，难以完成局部分析。本文借助有限元方法，建立玻璃钢烟囱的精细有限元模型，按照荷载组合，进行结构的有限元分析，得到结构局部的应力应变状态，然后按照各向异性复合材料层合壳理论对玻璃钢烟囱进行强度分析，应用Tsai—Wu强度比理论对烟囱结构进行了校核，达到了比较好的效果。

英文摘要：

Since there are not many specifications applied to design fiber-reinforced-plastic （FRP） chimney in China, so specifications on steel chimney , reinforced concrete chimney and masonry chimney are employed to de- sign FRP chimney. However, this method has many limitations： for FRP chimney is simplified as the isotropic can- tilever model which has neglected characters of composites, so it＇s hard to make local structural analysis. In this ar- ticle, a sophisticated finite element model of FRP chimney is built, then the structural responses under multi-load- ing cases according to current codes are performed. Stress and strain condition of the local area of FRP chimney are obtained, and strength analyses are proceeded according to laminated anisotropic composite shell theory and Tsai-Wu failure criteria. This way can realize more exact design than the conventional method.
