The production of steel structures is more to solve the problem of roof span, but with the evolution of contemporary aesthetic consciousness and the support of software technology, the architectural form of large-scale public buildings has become more complicated, which makes traditional structures unable to solve the distorted architectural form well. Due to its advantages such as easy processing, lightweight, and convenient construction, steel structure can be calculated integrally with the curtain wall system, and it is widely used in the shaping of complex building shapes in modern times.
The main building of the Daqing Highway Passenger Transport Hub consists of a three-story station and a 14-story information center, which are harmoniously connected. The entire project has a construction area of nearly 30,000 square meters. The passenger building is mainly made of steel and some concrete. structure. The steel structure is used to achieve complex appearance shapes and large-span roofs. The combination of steel structure and concrete structure supports the formation of a stable structural system.
To reduce the complexity of the roof of the Daqing Highway Passenger Transport Hub, the three-dimensional change of the hyperboloid is not adopted, and the single-curved form is adopted in the roof combined with the drainage direction. The roof of the large space at the bottom of the building still adopts the most economical and reasonable space frame form, and the roof system has not made many breakthroughs. The difficulty of the project is how to unify the form and structure of the complex facade. The bars of the main facade of the building along the street adopt irregular diagonal support. The steel structure of this part is integrated with the curtain wall system to form an overall vertical structure system, which not only supports the roof but also satisfies the wind resistance of the curtain wall. Due to the lack of vertical members on the main facade, the overall bearing capacity is insufficient, so vertical triangular supports are added to the middle part of the indoor space frame to reduce the roof load pressure of the main facade’s curtain wall structure.
