复杂曲面造型的钢结构设计

Steel Structural Design of Complex Surface Modeling

某高层项目设计中,建筑师设计了一个双向曲面的外立面造型。该造型体量大,不同位置的支座条件存在很大差别;同时受建筑方案限制,结构的刚度较弱且受力较复杂。结构工程师通过不同结构方案、不同工况下构件内力的比较,分析该造型整体结构和局部构件的受力特性,采取相应加强措施,进行构件和节点的优化,并对局部复杂节点进行应力分析,在满足建筑要求的同时,保证了该造型结构的安全。

In the design of a high-rise project,the architect designed a double-sided curved facade shape,which has a large volume and significant differences in the support conditions at different positions.At the same time,due to the limitations of the building scheme,the stiffness of the structure is weak and the stress is complex.Structural engineers compare the internal forces of components under different structural schemes and working conditions,analyze the stress characteristics of the overall structure and local components of the shape,take corresponding strengthening measures,optimize the components and nodes,and conduct stress analysis on local complex nodes.While meeting the building requirements,the safety of the shape structure is ensured.
