ABSTRACT:

Cable-frame type of suspended single-layer reticulated shells with free surface proposed by the author of the present paper is a novel type of large-span hybrid spatial structures. The whole design procedure regarding a practical gymnasium steel roof using this structural system is presented. System constitution including form finding of the upper structure and shape determination analysis of the lower cable-bar system is given out in details and emphasized. Load/action effects are thoroughly summarized for member sections design. A special joint design when diagonal cables penetrating the corresponding upper steel beam member is also brought forward. Hopefully the present paper could benefit the further research and practical engineering on hybrid spatial structures.
