Structural design of a single-layer spherical latticed shell
The characteristic of single-layer latticed shell structures is the nonlinear relationship between its stiffness and displacement,and the nonlinear stability analysis is crucial to the safety of structural engineering.The structural design of a single-layer spherical latticed shell glass skylight roof is discussed,the stability analysis of latticed shell structures considering geometric nonlinear analysis and material nonlinear analysis,the finite element analysis of key joints with complex loading conditions,and the detailed design of joints are given.The analysis indicates that nonlinear stability analysis and finite element analysis of critical joints can ensure the safety and reliability of engi-neering design,and the methods employed can serve as a reference for similar engineering projects.
