Abstract
A long-span structure engaged with a plurality of first and second transportation devices for moving the long span structure. The transportation devices travel along parallel, longitudinally-oriented first and second tracks; moving the structure between a first position and a second position. A first region of the structure is fixed to each first transportation device. A second region of the structure is secured to each second transportation device via a bearing assembly. The first and second regions of the structure are laterally spaced apart. When the long-span structure thermally expands or contracts, a slider plate of each bearing assembly moves laterally relative to the rest of the bearing assembly. Growth of the structure in a predictable direction is forced by keeping the first region thereof fixed against lateral movement with the first transportation devices and allowing movement of the second region thereof via the bearing assemblies on the second transportation devices.
