Based on the huge ellipsoid lattice shell structure in the atrium of the Shanghai Science&Technology Museum, this article briefly introduces the lectotype of lattice shell structure. The force-bearing properties of the steel and aluminum lattice shell are compared under vertical loads, temperature and seismic forces with rigid connection and rigid, winge and elastic supports. The study provides foundation for the nonlinear analysis of the lattice shell structures.
