Key and difficult points in the design of airport terminal curtain wall

Key and difficult points of modern curtain wall design of large airport terminal 1) Comprehensive determination of curtain wall type and structural system; 2) Establishment of the mechanical relationship between curtain wall structure system and main structure; 3) the relationship between the construction expansion joint structure and the curtain wall structure (including the boarding bridge); 4) Conceptual design and calculation analysis of curtain wall spatial structure system. 5) The curtain wall structure itself and its connection with the main structure; 6) the building curtain wall and the main building edge closing (opposite panel) treatment; 7) the curtain wall and the main building mutual displacement adaptation (wind, earthquake, temperature) structural waterproof design. 8) the rigidity, strength and hardware connection of the oversized electric opening window. Key points of curtain wall structure design of large airport terminal 1) Must understand the curtain wall panel layout and its partitions (generally proposed by the architect and fully familiar with the design institute drawings). 2) Familiar with the main structure support behind the curtain wall (floor, beam and column, roof structure, etc.). 3) Understand the boundary conditions of the main structure to the curtain wall (especially to the cable structure). 4) Requirements of architects and owners on the structural type of curtain wall. 5) the stress characteristics of various types of curtain wall systems; 6) various types of structure applicable conditions; 7) Do not blindly pursue the use of cable structure, especially single cable, the use of cable structure on the boundary conditions of high requirements, because the construction structure design after the end of curtain wall design, design institutes often do not consider the tension load. Curtain wall cable structure and main structure have mutual influence. The deformation of the main structure has a great influence on the pre-tension of the cable structure. 8) The geometric non-linearity must be considered in the calculation of single cable structure. The tension of cable structure of curtain wall construction has a great influence on the adjacent cable structure. The cable tension calculation during construction must be carried out to reasonably determine the tension scheme of the cable structure's prestress. 9) Attach importance to the reliability of steel structure connecting nodes (lug plate, pin shaft, weld calculation, etc.); The connection is very important 10) The slenderness ratio and out-of-plane stability should be considered in the stability calculation of steel structure. Some calculation software can not calculate the stability of steel structure, if necessary, it should be checked manually. The support outside the plane should be guaranteed reliably.
