摘　　要：义乌市文化广场为含大量大跨、大悬挑、重载的平面及竖向均不规则的复杂结构。主体结构根据各部分具体建筑功能、跨度合理选择采用钢筋混凝土结构、型钢混凝土结构、钢结构等局部结构形式。通过系统性和针对性的结构设计,结构承载力、延性得到了保障。重点阐述了大悬挑屋檐和连接体连接方式的选型并分析了此连接体的受力特性。各项计算结果表明,此连接体结构受力合理,传力直接。保证建筑使用功能的前提下,既满足了结构的安全性,又兼顾了经济合理性。Yiwu Cultural Square is a complex structure with a large number of large span,large cantilever and heavy load,which is irregular both in plane and vertical.According to the specific building function and span of each part,the main structure reasonably adopts reinforced concrete structure,steel reinforced concrete structure,steel structure and other local structural forms.Through systematic and targeted structural design,the bearing capacity and ductility of the structure were guaranteed.Focuses on the selection of the connection mode of the large cantilever eave and the connector,and the mechanical characteristics of the connector was analyzed.The calculation results show that the connecting structure has reasonable force and direct force transmission.On the premise of ensuring the use function of the building,it not only meets the safety of the structure,but also takes into account the economic rationality.
