In actual concrete arch dam engineering scenarios, the dynamic data obtained by health monitoring system of an are incomplete. The acquired typically depend on state structure, that is, whether it is intact or Besides, future environmental loads structure unpredictable. Thus, noise also uncertain. practical engineering, use a damage identification model constructed based incomplete information ...

An efficient optimization procedure is introduced to find the optimal shapes of arch dams considering fluid–structure interaction subject to earthquake loading. The optimization is performed by a combination of simultaneous perturbation stochastic approximation (SPSA) and particle swarm optimization (PSO) algorithms. This serial integration of the two singlemethods is termed as SPSA–PSO. The op...

Arch dams have delicate sections thanks to their curvature. The fact that these are large, costly and construction takes many years increases the importance of structure. Mistakes / or accidents may occur during such structures major loss life property. Considering volumes, masses slenderness arch dams, they can be significantly affected by dynamic forces as changing water pressure, temperature...

In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...
