广交会琶洲展馆综合楼主体结构设计

Subject Structure Design in Pazhou Complex of Canton Fair

通过对框架核心筒超高层结构选型的综合分析比较,确定其优选方案为钢-混凝土混合结构,塔楼框架柱采用矩形钢管混凝土柱,并采用构造简单的变截面式加腋梁柱节点,提高节点的耗能能力,同时根据节点试验建议,提出钢管柱与钢筋混凝土梁和钢梁,剪力墙与钢框架梁之间的刚性连接节点大样,可供类似工程参考使用。

Based on the comprehensive analysis and comparison of frame-corewall structure of tall building,determine the structure optimization--steel-concrete mixed structure. Tower columns use Concrete-Filled Rectangular Steel Tube （CFRST）. The simple cross-section type haunched,improve beam-column nodes of energy dissipation capacity. According to the test,and puts forward Suggestions for CFRST column with steel reinforced concrete beams or steel beams of rigid connection,and the shear wall with steel frame beams of rigid connection. These use for reference in similar engineering.
