Design content: steel structure construction drawing design, independent completion of steel structure deepening design and construction process analysis

工程概况：

该项目与英国奥雅纳工程顾问公司合作完成钢结构施工图设计、独立完成钢结构深化设计及施工过程分析。结构形式为73层钢-混组合结构，建筑地下3层，地上73层，建筑高度为330米，总建筑面积约为25万平方米，总用钢量约为5万吨。

Project Overview:

The project cooperates with Arup Arup to complete the steel structure construction drawing design, and independently completes the steel structure deepening design and construction process analysis. The structure is a 73 storey steel-concrete composite structure, with 3 floors underground and 73 floors above the ground. The building height is 330 meters, the total building area is about 250000 square meters, and the total steel consumption is about 50000 tons.

国贸大厦A座主楼钢结构构件数量共2.3万件，平均每天54吊次。同时，主楼混凝土结构和机电幕墙装修辅助吊次仍需要占用大量吊次。此外，由于国贸三期工程主塔楼为型钢混凝土组合结构，总用钢量为5.5万吨，混凝土浇筑总量为18万立方米，钢筋用量为4万吨，工程超高层钢结构含地下室共77层。

There are 23000 steel structural members in the main building of block a of the international trade building, with an average of 54 lifting times per day. At the same time, the concrete structure of the main building and the auxiliary lifting times of electromechanical curtain wall decoration still need to occupy a large number of lifting times. In addition, as the main tower of the international trade phase III project is a steel reinforced concrete composite structure, the total steel consumption is 55000 tons, the total concrete pouring volume is 180000 cubic meters, and the steel consumption is 40000 tons. The super high-rise steel structure of the project includes 77 floors of basement.
