Abstract:The main structure of Longhua Sanctuary in second-stage project (Maitreya Altar) of Zhejiang Buddhist Institute is a large-span single-layer reticulated shell structure. The maximum length of the structure plane is 184m, the north-south span is 104m, and the east-west span is close to 120m. Its layout and span are rare single-layer reticulated shell structures in China. The characteristics and key technologies of the structural system of the project were introduced emphatically, and elastic analysis, stability analysis and joint finite analysis were conducted on the main structure, and the structural design and relevant details were introduced. Through the analysis and research, the project optimized the conventional layout of bent-torsional members and joint structures of single-layer reticulated shell structure, providing reference for other similar projects.

Keywords:Longhua Sanctuary; single-layer reticulated shell; heteromorphic reticulated shell; stability; bent-torsional member; cast-steel joint
