seismic behavior assessment of concrete elevated water tanks

چکیده
elevated tanks are very important structures and consist of various types. water supply is vital to control fires during earthquakes. also they are utilized to store different products, like petroleum supplies in cities and industrial zones. damage to these structures during strong ground motions may lead to fire or other hazardous events. elevated tanks should stay functional after and before earthquakes. however their dynamic behavior differs greatly in comparison with other structures. in this research, a sample of reinforced concrete elevated water tank, with 900 cubic meters capacity, exposed to three pair of earthquake records have been studied and analyzed in time history using mechanical and finite-element modeling technique. the liquid mass of tank is modeled as lumped masses known as sloshing mass, or impulsive mass. the corresponding stiffness constants associated with these lumped masses have been worked out depending upon the properties of the tank wall and liquid mass. tank responses including base shear, overturning moment, tank displacement, and sloshing displacement have been calculated. results reveal that the system responses are highly influenced by the structural parameters and the earthquake characteristics such as frequency content.

متن کاملSeismic Behavior Evaluation of Concrete Elevated Water Tanks
Elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. These structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. Damage to these structures during strong ground motions may lead to fire or other ...

elevated water tanks as one of the main lifeline elements are the structures of high importance. since they are extremely vulnerable under lateral forces, their serviceability performance during and after strong earthquakes is a matter of concern. as such, in recent years, the seismic behavior of water tanks has been the focus of a significant amount of studies. in the present work, three reinf...
متن کاملEvaluation of Seismic Behaviour of Ferrocement Elevated Water Tanks by Using Ambient Vibrations Tests
In this study a series of ambient vibration tests on the triple ferrocement elevated water tanks with 150 cubic meters volume, is carried out. In order to verify the dynamic characteristics of full, half-full and one full tanks (mass eccentric system), the different arrangements of sensors are used. The effects of base rotation are also considered in the tests. Natural frequencies and mode shap...
متن کاملImproving seismic performance of elevated cylindrical water storage tanks using nonlinear isolators incorporating liquid–structure interaction
Pervasive construction of elevated liquid tanks as the most important sources for urban hygienic water, and their failure under earthquake, highlighs the necessity for research toward new passive control devices. Design and use of base-isolation systems for elevated liquid tanks is propounded as a novel seismic engineering technology. To date, no special examination has been discussed in relati...
