摘　　要：欧加大厦项目结构形式为“钢框架+钢筋混凝土核心筒”,钢结构部分主要包括塔楼外框钢柱钢梁、核心筒内插钢柱钢结构,主要构件截面有圆管、H形、箱形,在出正负零标高底层转换处有各种截面组合成集束柱。制作难度大、结构复杂、要求精度高,并且行业内无类似工程结构项目借鉴,需要自行分析整合评审总结最佳加工制作工艺方案。The structural form of the project is“Steel frame+reinforced concrete core tube”.The steel structure mainly consists of steel beams of steel columns in the outer frame of the tower and steel columns inserted into the core tube,the cross-sections of the main components are circular tube,H-type,box-type,at the bottom of the zero-level conversion of positive and negative cross-sections combined into a cluster column.It is difficult to manufacture,complex structure and high precision,and there is no similar engineering structure project in the industry.
