8. The system of claim 1 , wherein each of the one or more center sections is at least 12 feet or 3.6 meters long.

9. The system of claim 1 , wherein the arches comprise snap connections adapted for assembly thereof.

10. The system of claim 1 , wherein the system is configurable in one or both of the first and second configurations without welding.

11. The system of claim 1 , wherein:

the pairs of leg beams comprised by the arches of the second configuration are substantially the same or identical to the pairs of leg beams comprised by the arches of the first configuration;

the pairs of eave beams comprised by the arches of the second configuration are substantially the same or identical to the pairs of eave beams comprised by the arches of the first configuration; or

the apex beams connected to form the arches of the second configuration are substantially the same or identical to the apex beams connected to form the arches of the first configuration.

12. A method for providing the system of claim 1 , comprising:

configuring the frame in a selected configuration of the first configuration or the second configuration;

wherein the leg beams, eave beams and apex beams of the selected configuration are connected to the first or second plurality of straight roof beams of the selected configuration to form the plurality of arches of the selected configuration.

13. The method of claim 12 , further comprising:

removing at least some of the first or second plurality of straight roof beams, corresponding to the selected configuration; and

replacing said removed straight roof beams with at least some of the first or second plurality of straight roof beams corresponding to another of the first or second configuration, different from the selected configuration;

wherein the leg beams, eave beams and apex beams corresponding to the selected configuration are connected to the at least some of the first or second plurality of straight roof beams corresponding to the other configuration, forming the plurality of arches thereof.

14. A structural system comprising:

a frame configured in a selected configuration, the frame comprising:

one or more center sections formed from a plurality of arches defining an open end and a second end, wherein each of the arches comprises a pair of leg beams and a pair of eave beams;

a first plurality of straight roof beams and an apex beam connected to the leg beams and eave beams to form the arches, in the selected configuration;

at least one of a door unit, a gable end, or an open end of an additional such center section, connected to the open end of one of the center sections, wherein said door unit, gable end or open end is removable and replaceable with another such door unit, gable end or open end; and

a second plurality of straight roof beams, different from the first plurality of straight roof beams, wherein at least some of the first plurality of straight roof beams are replaceable with at least some of the second plurality of straight roof beams to reconfigure the frame in another configuration, different from the selected configuration;

wherein the first and second pluralities of straight roof beams have different lengths selected to change a width of the structural system in the other configuration, as compared to the selected configuration.
