Many water tanks are pull-down during post-earthquake due to failure of water tank staging and this occurs because of the dynamic behaviour of the water tank staging that leads to collapse of water tank. These are important elements during post-earthquake that must be in service. In this study to reduce the damage of water tank staging by installation of additional dissipation devices known as dampers made up of X-plate steel and aluminum and these are effective in reduction of damage of structures, gives the additional damping and additional stiffness to the structure. For this study water tank staging’s with different heights are modeled in SAP-2000 and performed nonlinear dynamic analysis under four real ground motions with and without damper. After the analysis the results obtained is, Displacement, shear force, amount of energy dissipation, maximum axial force and bending moment compared with and without damper and significantly reduced.

“…In this paper the X-plate dampers are introduced in structure in order to reduce ground induced vibrations. Performance of structure against blast and seismic vibrations without damper is also evaluated e.g., Manchalwar and Bakre (2016).Study on response of structure under blast loads is referred from Draganićn.H and Vladimir.S (2012) [6,7].

This study is an attempt to evaluate the effects of blast induced vibrations and seismic ground vibrations on reinforced concrete structure equipped with X-plate dampers and also to study the response of structure against blast and seismic vibration which can be reduced by employing protective systems such as dampers. Moment-resisting RC frame buildings were analysed to evaluate the structural responses under dynamic excitations. Non-linear Time-history analysis has been conducted on reinforced concrete structures. The ground accelerations were analytically determined and model was created in SAP2000.

“…Komur (2015) [7] The isolation mechanism thus moves the time period of the structure to a high value and/or dissipates the energy through damping, reducing the amount of force that can be transferred to the super structure to significantly minimize inter-story drift and floor acceleration, see e.g., Matsagar and Jangid (2018). [4] Dampers were modeled in each story on the building's outer frame. The dampers significantly decreased measures of damage such as displacement and drift.…”

In the present paper base isolation system is analyzed and its seismic behavior is investigated using U-shaped steel dampers as an isolator by placing it at the bottom of the structure. It is the most popular way of protecting the structure using control techniques for earthquake ground motion. The dampers significantly reduced damage factors such as displacement and drift. To reduce structural response to external forces, which can be accomplished through the use of special protective systems. So to prevent these damages, seismic isolation technique can be used for newly constructed structures. The time history analysis of the time domain on this structure is conducted by using SAP2000 software
