树形木结构的形态与稳定性能研究

Morphological and Stability Reserch for Tree-like Timber Structures

树形结构是一种新颖的结构形式,在工程实践中得到了大量应用。通过分析国内外树形结构工程的结构特点,总结了适用于木结构的树形结构特征。采用计算长度系数法对典型树形木结构的稳定性进行分析,并给出了相应的分析结果和参数设计建议。通过对典型树形木结构工程——美国比弗顿图书馆进行结构分析,得到各杆件计算长度系数均满足建议取值,为今后树形木结构的设计提供参考依据。

Tree-like structure was a neoteric form, so it summarized the feature of tree-like structure which applied to was widely used in engineering. The article timber structures by analyzing characteristics of tree-like structure engineering, both in China and abroad. The analysis of stability of tree-like timber structure was made by effective length method and some suggestions of reasonable grade bracing and the corresponding design parameters were given. By making the analysis of structural behavior of Beaverton Library, it indicated that effective length was satisfied with suggestions and it provided a reference basis for tree-like timber structure design.
