Cable-net systems supporting glass facades

Abstract

: Prestressed cable-nets supporting large glass facades are increasingly used for unique structures and studied both experimentally and numerically. Presented paper deals with numerical geometrically nonlinear analysis of planar and double curved cable-nets without and with glass panes attached to the net with clamped fittings. The numerical model established in ANSYS is described and fully validated by published tests (Yussof, 2015). The results confirm the need for taking the glass stiffness into account. It is proved a greater stiffness of curved cable-nets in comparison with the planar ones and a need for careful arrangement of prestressing for curved cable-nets in sagging/hogging cables. Another study will follow with detailed research concerning optimal and safe design of the systems.
