barrel vault space frame is a kind of space structure that is widely noticed nowadays. It is a grid structure, suitable for covering the rectangular plane of an industrial workshop, warehouse, swimming pool, tennis hall, aircraft hangar, and so on. In the past, simple reticulated shells were mostly single-layer structures, but now the Mero system is double-layer tubular reticulated shells (bi-directional rectangular lattice) with a net span of 100 meters. The analysis shows that the most economical plane of single-layer tubular reticulated shells should be approximately square.
