The large-span double-curved space truss steel structure is renowned for its striking aesthetics,grand design,and high space utilization,making it a preferred choice for important construction projects.However,this type of structure presents challenges such as complex form,extensive span,intricate fabrication and installation processes,and high technical requirements.The Beijing Grand Theater metro station adopts a large-span double-curved space truss steel structure,which has a very characteristic shape.Based on this,this article takes the Beijing Grand Theater metro station project as a case study,delving into the overall design scheme and structural installation steps.The adopted approach encompasses a"chord-supported dome structure+bi-directional staggered cross-lattice roof+center-floor planter column+circumferential auxiliary support system".This article studies and summarizes the key technologies involved in the construction of the double-curved space truss steel structure,aiming to provide a technical foundation for the innovative development of steel structures.It also serves as a reference and example for similar projects in the future.
