In addition to the hydrostatic pressure, the dome structure has to carry its own weight and a skin cover load. The loads are assumed to be transmitted through the dome structure to the supporting ring foundation via membrane forces only. By adopting a fully stressed design, the problem in hand is to determine the shape and thickness variation of the submerged dome. The set of nonlinear differential equations and boundary conditions constitute a two-point boundary problem that can be solved by a shooting-optimization method. Based on a family of fully stressed designs associated with a given water depth and dome height, the optimal dome shape for minimum weight is identified. © 2005 Civil-Comp Press. | Source Title: | Proceedings of the 10th International Conference on Civil, Structural and Environmental Engineering Computing, Civil-Comp 2005 | URI: | http://scholarbank.nus.edu.sg/handle/10635/84727 | ISBN: | 1905088000 |
