Analysis of cable net-panel roof system

Abstract The study presented in this paper deals with the analysis of a cable net roof system with precast panels which are prestressed to increase the stiffness of the system. The roof structure can be stiffened by applying a temporary load to the structure after the precast panels are hung in place on the cable net, filling the space between the panels with concrete, and. after the concrete has cured sufficiently, removing the temporary load. This in effect, prestresses the monolithic roof structure. A computer program was developed to analyze a cable net roof structure and an experimental investigation was carried out to verify the theoretical analysis performed by the computer program and to study the response of a cable net-panel system during the prestressing of the panels. The model used in the experimental study was a 4 × 4 cable net with nine panels.
