| Abstract |
This paper is concerned with the erection of an arch shaped space structures by post-tensioning. It is a fast and economical method for constructing such an arch by post-tensioning of the cable in bottom chords. This structure consists of uniform pyramids with multi-directional joint in a flat layout on the ground, and then the structure is shaped and erected into its final purposed shape. The feasibility of the proposed erection method and the reliability of the established geometric model were confirmed with numerical analysis and experimental investigation on a small scale test model. As a results, the Total Lagrangian(TL) and Updated Lagrangian(UL) method can be used in shaping analysis of an arch shaped space structure, we can find the most reasonable modeling technique for the prediction of shape formation in practices and we can know the characteristic of the behavior in shaping test for practical design purposes. |
