[0002] In recent years, with economic development, the use of large-span roofs has increased, and their shapes have become more diverse. Double-layer spherical lattice shells, with their simple shape and practical interior space, have become increasingly popular among architects. Double-layer spherical lattice shells are a type of architectural structure composed of two layers of curved grids, usually spherical or partially spherical in shape. Due to their unique geometry and excellent mechanical properties, these structures are widely used in swimming pools, gymnasiums, exhibition halls, and other fields. In engineering design, functional rooms such as changing rooms, rest rooms, and supporting facilities are set up within the building according to usage requirements. Reinforced concrete frames or steel frame structures are generally used to form "rooms within rooms" within the building, thereby reducing the scope of large-span open space and affecting the internal architectural effect.
