Disscussions on Shape Determination of a New Space Beam-String-Structure with Outer Truss Torus

Abstract:

Space beam-string-structure with outer truss torus is a new type of space structure. The new structural system is to reduce the space occupied by roof structure and could be laid by the rigid roofing material conveniently. Based on the local analysis method and the whole system balance, a simplified calculation method for initial prestress of ribbed grid space beam string structure were proposed when the cable curve equation was determined. An example was investigated and the results confirmed the feasibility of the proposed method.
