Blast Response of Elevated Water Tank Staging with Metallic Damper

In the present paper work an attempt has been made to study the dynamic behaviour of the elevated water tank staging by using x-plate metallic damper subjected to blast induced ground vibrations. The main objective of this study is to reduce the damage of the elevated water tank by providing structural response control devices. The water tank staging is modelled in SAP 2000 and non-linear time history analysis is carried out to know the performance of the metallic damper under four different intensity blast induced ground motions and comparing the performance of structure without damper case. After the completion of analysis, the results show that by using metallic damper bending moment, shear force and displacements are comparatively reduced when compared to the without damper case. From this study observed that metallic x-plate damper is effectively reduced the structural responses under blast excitations
