Abstract
This research discusses the seismic response of the elevated water tanks
which is represented by the base shear forces, displacements and bending
moment values, and also studying the dynamic characteristic for this type
of especial structures, such as the period and frequencies of vibration , all
these are done by dynamic analysis for 3-D mathematical models
according to response spectrum ,with considering the fluid-structure
interactions by representing this fluid with spring-two masses equivalent
system: impulsive and convective masses .This analysis has been done by
SAP 2000 program . This research involves studying the effect of friction
pendulum system (FPS) in dissipating the vibration energy caused by
seismic effects on the elevated tanks, and the influence to the response and
dynamic specifications values. Also, in this paper the seismic behavior of
these elevated tanks which are supplied by tuned mass damper has been
evaluated.
A reinforced concrete- elevated water tank has been analyzed and the
dynamic analysis results of these seismic isolated tanks showed that the
displacements, base shear forces and bending moment generally decreased
