Geleng is a Sasak vernacular building that serves to store agricultural products in a traditional house in the island of Lombok, Indonesia. There are also other names for the Geleng, depending on the village. In the village of Limbungan, it is called Panteq. In Senaru village and in Sembalun village it is called Geleng. In Sade village, it is called Bale Alang. During the magnitude-7 Lombok earthquake, Geleng was able to withstand the earthquake. This fact proved that Geleng has a high resistance to earthquakes. This study investigates the reasons for the high earthquake resistance of the Geleng building. Data was collected using a survey in the villages of Limbungan, Beleq Sembalun, Senaru, and Sade. The number of Gelengs investigated were: six in Limbungan, one in Sembalun, and three in Senaru. Bale Alang in the Sade village was not included in this study because it has a different roof structure from the Geleng in the other three villages. The dimensions of the Geleng structural elements are measured and the drift ratio capacity is calculated. The results of this study show that the Geleng structure of Sembalun village has the highest drift ratio capacity, which is 72.0%. This is followed by the Limbungan village at 71.5% and the Senaru village has a drift ratio capacity of 54.5%. This result proves that all the Geleng buildings have a drift ratio capacity that exceed the minimum drift ratio requirement for earthquake-resistant structures, which is 3.5%. © 2022.
