ANALISIS BANGUNAN SEDERHANA KAWASAN TERLIKUIFAKSI

Abstract

Liquefaction is one of the dangers caused by earthquakes. When the earthquake occurs, the soil undergoes a change in properties from solid to liquid due to the cyclic load received. This research aims to identify the structure of a one-story house building with simulated soil and analyze the decreases that occur due to soil and building loads are reviewed based on floor plate thickness used as percutaneous structures. The method used in this study is a structural analysis method using building exsisting soil data based on the results of the Cone Penetration Test (CPT). Data were collected through observation, interviews, documentation, and literature studies which were then analyzed using SAP 2000 version 11. Software analysis results from outside and inside building points showed that the inner force in the column experienced a decrease in the value of the force. The decrease is caused by giving the plate to the floor so that the structure becomes rigid while the latitude and normal moments experience a significant decrease. Whereas building declines that occur after being given a floor plate are uniform so that the use of ground floor plates can be used as a new method in the problem of building decline. This study provides recommendations to the government to be considered in making policies on buildings that are in simulated land.
