Abstract

West Sumatra Province, especially Padang City, is an area prone to the earthquake that is not only can trigger a tsunami but also liquefaction disaster. In order to face the disaster, the Padang city government planned to build as many as shelters as a vertical evacuation building. One of them is Nurul Haq shelter located in a coastal area that has high liquefaction potential. A structural evaluation of the shelter was conducted to check the capacity of the existing shelter structure in resisting the working loads. From the result of the soil evaluation, it was found that the soil in the shelter location has high liquefaction potential. Therefore, the shelter structure is analyzed using specific response spectrum of the earthquake loads considering soil liquefaction, which is 1.5 higher than those on the non-soil liquefaction. The tsunami loads were calculated used based on FEMA P-646. The analysis result shows that the shelter building is not capable of resisting the working loading, in which the elements of the beams and foundations don’t have enough capacity to resist the working loads, especially earthquake and tsunami loads. Furthermore, the shelter building should be retrofitted before being used as a vertical evacuation building.
