Summary

The remarkable rigidity and economy of three-dimensional space structures have long been realized, but only during the last decade have they begun to come into widespread architectural use. In an age of standardization and prefabrication, their simplicity of manufacture, ease of transportation, and speed of erection are sufficient recommendation. Even more important, however, the ratio of weight to area covered can be greatly reduced through their use, and they allow the construction of long-span structures with a far smaller number of intermediate supports.
