Trussed domes are structures whose general overall shape is that of a dome whose structure consists of a skeletal main framework to carry the internal forces and a skin applied to this frame that creates the actual enclosure. The overall geometric effect of the space enclosed by these domes does not differ substantially from that of a masonry dome, but from a structural point of view there are two distinctly different systems. On the one hand, it could be said that the overall structural behavior of a trussed dome is the same as that of a masonry dome: the zones of compression and tension throughout the dome’s surface are the same in each case. On the other hand, there is a substantial distinction between a continuous structural surface and a discontinuous skeletal structure.
