［摘要］采用SAP2000對不同斜柱角度的高層斜交網(wǎng)格筒結(jié)構(gòu)模型進行了彈性分析和靜力彈塑性分析。探討了斜交網(wǎng)格筒結(jié)構(gòu)抗側(cè)剛度的發(fā)展過程；總結(jié)了斜交網(wǎng)格筒結(jié)構(gòu)塑性發(fā)展過程及構(gòu)件屈服順序，明確了斜交網(wǎng)格筒結(jié)構(gòu)的屈服路徑；分析了主環(huán)梁跨高比對斜交網(wǎng)格筒結(jié)構(gòu)剛度和塑性發(fā)展過程的影響，以及斜柱的受壓性能對斜交網(wǎng)格筒結(jié)構(gòu)延性的影響。結(jié)果表明：高層斜交網(wǎng)格筒結(jié)構(gòu)的延性較差，結(jié)構(gòu)的剛度和承載力退化不明顯；提高斜柱截面的受壓性能能夠明顯改善結(jié)構(gòu)的延性；主環(huán)梁跨高比對斜交網(wǎng)格筒結(jié)構(gòu)的剛度發(fā)展過程影響很小。［關(guān)鍵詞］斜交網(wǎng)格筒; 抗震性能; 彈性分析; 靜力彈塑性分析中圖分類號：TU352.1 文獻標識碼：A 文章編號：1002-848X(2016)04-0008-07
Seismic behavior analysis of high-rise diagrid tube structural systemShi Qingxuan, Ren Hao, Wang Bin, Li Tong(School of Civil Engineering, Xi'an University of Architecture and Technology, Xi'an 710055, China)Abstract: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.Keywords:diagrid tube; seismic behavior; elastic analysis; Pushover analysis
