| Abstract: | Through researching into the computing theory of prestressing shell of hyperbolic paraboloids,the paper gives the unit rigidity matrix of prestressing steel cable,and presents the concepts of the whole rigidity assemblage.Based on the three projects in Guangdong,China,the author probes into the results of prestressing force,the optimization of cable force of hyperbolic paraboloids shell,the losses of prestressing force and the effects of pedestal changes.The paper also provides the computing formulas for pedestal restraint rigidity. |
