ANALISIS DISPLACEMENT GEDUNG BETON BERTULANG TINGKAT TINGGI TERHADAP BEBAN GEMPA SESUAI PETA GEMPA INDONESIA 2017 DENGAN ANALISIS TIME HISTORY
Abstract
An earthquake is a natural disaster that cannot be avoided. Indonesia is an earthquake prone region because it is in the active Pacific ring area. In Indonesia, high-rise buildings have different levels of security, this can be caused by the type of soil or the frequency of the earthquakes that occur. This study uses the structure of a high-rise building with 8 floors and 1 basement that was tested on 99 selected cities on the Indonesian earthquake map with 3 different types of soil. The earthquake loading method used a time history analysis obtained by adjusting the record of the earthquake history that has been obtained by spectrum response from 99 cities that are sought by the Seismomatch program so that the data is close or appropriate. SC, SD and SE sites have 3 records of earthquake records. The earthquake data will be entered into the building that will be used as a trial. The results of this study indicate that 53 cities passed the permit limit and entered the unsafe category. The smallest percentage approaching the permit deviation limit is in the city of Banda Aceh which is equal to 0,25 %, while the largest unsafe percentage is in Gorontalo city at 183,18 %
