Structures under controlled motion

Controlled motion may be a convenient feature of a structure during its construction or even in itsservice phase. This paper shows three cases of structures in which movement plays an important role.The two first examples (a medium span bridge and a roof) show how motion contributes to asuccessful construction process. The third one, a solar tracking device, exemplifies a structure designedfor continuous motion. Special aspects of the design, construction process and monitoring are shown ineach case.
