This study deals with the capabilities of artificial neural networks in lea
rning to control water towers of different structural properties that are s
ubjected to earthquakes. To this end, water towers were considered as singl
e-degree-of-freedom systems. First, a number of water towers of different s
tructural properties were controlled by the predictive optimal control meth
od, and then the data collected through this control were used in the train
ing of a general neural network controller, called the general neurocontrol
ler. Capabilities of the general neurocontroller were tested in the control
of a number of water towers with structural parameters different from, but
in the range of, those used in its training. One of the aims of this study
was the introduction of general neurocontrollers as ready-to-use devices t
hat may be used in the design of actively controlled structures, in this ca
se, water towers. Results of this numerical study were promising.
