Paper Details

Tsunami ― In Japanese “tsu” means harbor and “nami” means waves, so tsunami can be summed up asa harbor waves or seismic waves or tidal waves. They are water waves which are caused by submarine earthquakes.Wave movement with large velocity triggered but strong Earthquake at the sea bed is generally the primary cause oftsunami. It’s a natural event on which a man has no control, neither can he control the damage caused by it. Occurrenceof such natural calamities causes severe damage to the structure as well as to human lives too. Occurrence of tsunami(like the one during Indian Ocean tsunami on December 26, 2004, the Sumatra earthquake in 2004 or the one during theTohoku earthquake in Japan in 2011) caused devastating damages to the coastal structures and tremendous casualties.Such deadliest mega event made the coastal community realize the need for the preparedness against it. Also most of thetsunamis are earthquake induced tsunamis; hence it is necessary that coastal structures should be designed against bothearthquake and tsunamis.The community of structural engineer is well aware about the consequences of accidental and rare events likeEarthquake, Tsunamis, Fire, Tornado and Blast which leads to building failure and loss of life and property. Amongthem Progressive collapse is one of the most devastating types of building failures, which most often lead to costlydamages, multiple injuries, and possible loss of life. This paper deals with the hazards associated with the progressivecollapse triggered due to tsunami forces. In the present study an attempt has been made to give recommendations andsuggestions for the structures to be built upon the sea and large water bodies. For this G+5 hypothetical building wasmodeled in ETABS-2015 and the building was scrutinized by performing Non-Linear Static Analysis while following U.S.General Services Administration (GSA) document and Unified Facility Criteria – Department of Defense (UFC – DoD),USA guidelines along with FEMA-356 code of conduct. . From the study it was found that as we move away from theTsunami forces along Y-direction the criticality of Storey goes to Storey 2, 3 and 5 and maximum deflection is in storey5with 25.67% and 18.26% as compared to Storey 1 along Y and X direction respectively.
