<p>A method for constructing a vertically ring structure from a plurality of pre-fabricated arced segments. Each of the segments has at least one face arranged to engage with a face on an adjacent segment when in position. The method comprises a step of connecting two adjacent segments. A force is then provided tangential to the ring structure with pre-stressed cables in order to pull the two adjacent segments together and the procedure repeated for each of the segments of the structure. The structure is thereby held in position and resisting the tendency for collapse of the segments caused by their dead weight, throughout the construction process. The structure may be a Ferris wheel.</p> |
