Abstract: The catastrophic tsunamis generated during Tohoku, Japan (2011), Indonesia (2004) and Alaska (1964) earthquakes caused severe damage to life and coastal structures and warned the coastal community on prepared and constructing safe structures against such events. Since most of the tsunamis are triggered by undersea earthquakes , it is necessary to establish analytical methods for obtaining the variation of response parameters when tsunami waves hit exterior and interior columns when the similar structure rests on different soils. In this paper, a G+9 storey coastal structure is chosen for the analysis and the response parameters like bending moments, shear forces, time periods, displacements and base shears are worked out considering with and without the effect of Soil Structure Interaction (SSI). From the results it is observed that the multi storied structure is more vulnerable when it rests on loose soil compared to when it rests on stiff soil or hard rock and when it is fixed at the base.
Keywords: Tsunami, Hydrodynamic and Impact forces, Soil Structure Interaction, Base shears and Displacements, ending moments and Shear forces in column.
Scope of the Article: Sequential, Parallel And Distributed Algorithms And Data Structures.
