Space frame is a spatial structure connected by several pipe and node ball upon some regular pattern of geometric figure.
It changes the ordinary frame structure of the general plane stress state, and it can be bear the loads from all sides,even
though the individual pipe in damage, it can automatically adjust the member forces, to maintain structural safely.
Space frame has excellent performance which is much better than other steel structure. If the span is more than 40m,
space frame is more economical, safer, and with better seismic performance. Therefore, space frame is widely used
in large span of structure building.
