A collapsible building structure is disclosed which includes a pair of stressed membranes which are fixedly held in spaced relation when the structure is in its erected form. Lines of tension are formed in the membrane when the structure is erected which generally define rectilinear grid patterns. A plurality of node members are arranged on each of the two membranes such that each node member is separated by intersecting lines of tension. Paired nodes on each of the membranes are connected by a tensile member. Each of the nodes on one membrane are connected by a compression strut to the nodes on the other membrane which are most closely adjacent to its paired node on the other membrane. The building structure is selectively collapsed and re-erected by selectively tensing or relaxing the tension members. Building structures may also be formed utilizing flexible tension members connecting the node members which replace the stretched membranes.

A structure comprising: (a) first and second membranes disposed in spaced relation and having lines of tension defining corresponding rectilinear grid patterns in each of said membranes; (b) a plurality of node members attached to each of the two membranes such that each node member on said first membrane is paired with a corresponding one of said node members on said second membrane, said node members on each of said membranes being arranged along each line of tension such that each node member is located at an intersection of lines of tension in said membranes and is separated by intersecting lines of tension in said membranes from adjacent node members lying along the same lines of tension; (c) a plurality of tensile members, each said tensile members extending in tension from attachment to one of said node members on said first membrane to attachment to the node member on said second membrane that is paired with said one node member on said first membrane; and (d) a plurality of compression struts, said struts being arranged such that, at each node member on said first membrane, struts extend in compression from attachment to said node member on said first membrane to attachment to each of said node members on said second membrane which are most closely adjacent to and substantially equidistant from the node member on said second membrane which is paired with said one node member on said first membrane, whereby said struts will lie substantially along the diagonals of the rectilinear lines of tension which extend between adjacent node members.
