中文摘要：
采用SAP2000对不同斜柱角度的高层斜交网格筒结构模型进行了弹性分析和静力弹塑性分析。探讨了斜交网格筒结构抗侧刚度的发展过程;总结了斜交网格筒结构塑性发展过程及构件屈服顺序,明确了斜交网格筒结构的屈服路径;分析了主环梁跨高比对斜交网格筒结构刚度和塑性发展过程的影响,以及斜柱的受压性能对斜交网格筒结构延性的影响。结果表明：高层斜交网格筒结构的延性较差,结构的刚度和承载力退化不明显;提高斜柱截面的受压性能能够明显改善结构的延性;主环梁跨高比对斜交网格筒结构的刚度发展过程影响很小。
英文摘要：
By SAP2000,the models of high-rise diagrid tube structure with different angles of inclined columns were analyzed with elastic analysis and Pushover analysis methods. The development process of lateral stiffness of the diagrid tube structure was discussed. The plastic development process and the component yield order of the diagrid tube structure were summarized. The yield path of diagrid tube structure was clear. The influence of the span-height ratio of main ring beam on the structure stiffness and plastic development process of the diagrid tube structure was analyzed. Meanwhile,the influence of the compression performance of inclined column on the ductility of diagrid tube structure was analyzed. The results show that the ductility of high-rise diagrid tube structure is poor and the degradations of stiffness and strength are not obvious. Enhancing the compression performance of the section of inclined column can improve the ductility of the structure obviously. And the span-height ratio of main ring beam has little effect on the development process of the lateral stiffness for the diagrid tube structure.
