Earthquake-Resistant Design Principles of the Traditional House in Lombok Island

摘要

Indonesia lies above one of the active three tectonic plates on earth, which causes earthquake disasters frequently. In 2018 the island of Lombok was hit by a 7.0 Richter Scale earthquake creating major destruction of buildings. While most of the modern building construction damaged when hit the waves, some of the traditional houses in the Segenter region remained steady and safe from the disaster. This study examines the structural and construction system of some traditional houses safe from the waves in Lombok. It focuses on the views of the geometry of building, joint of structure-construction system, as well as building materials applied. Field observation was held to understand the details of constructions. Collected data were analyzed based on earthquake resistance design principles. The outcomes of this study would be beneficial for modern house designs in the future.
