The present study encompasses a comparison of the experimental and theoretical analysis of air supported cable roof structures. A 1:120 scale model of the Pontiac Silver Dome in Pontiac, Michigan, U.S.A., was used to substantiate the results obtained by the various solution techniques used in the theoretical study. The energy search method is compared to three standard one-step solution techniques presented by Baron and Venkatesan and Kar and Okazaki. Computer programs were developed using FORTRAN for all of the above solution methods to simulate various kinds of distributed loads on the structure. For the purpose of experimental study, the model was inflated with different air pressures and the nodal coordinates were measured for each case. Thereafter, keeping the internal pressure constant, the structure was loaded with different types of externally applied patch loads of sand to simulate live loads on the dome. Load-displacement curves at various nodes on the roof were plotted and compared to the theoretical results obtained. Finally conclusions are drawn and recommendations for further research are presented. (Abstract shortened by UMI.)Dept. of Civil and Environmental Engineering.
