Vulnerability Assessment on Non-Engineered Building in Earthquake Prone Area. Case Study: Klaten District, Central Java, Indonesia

Abstract

Most of the houses in Indonesia are still categorized as non-engineered buildings which do not use good structural analysis in the manufacturing process. The level of education and knowledge about the construction of simple houses is certainly the main cause. The geographical conditions of Indonesia which are quite prone to disasters such as earthquakes, eruptions and cause this condition is one of the real threats to the population of Indonesia. This study discusses the level of vulnerability of buildings in the Klaten area to earthquake hazards. This area is one of the areas affected by the earthquake in 2006, and the community living was rebuilt with funds from the Indonesian government. The results showed that at the time of the initial construction 95% of this building had been calculated to withstand earthquake loads, this was seen from the main building which had a fairly strong structural component and was equipped with a fairly good structural drawing. Along with the growth of the population, most of the buildings have undergone a change of shape, many people have added their own buildings without considering the strength of the construction to withstand earthquake loads. So that buildings that were initially categorized as resistant to earthquake forces are very dangerous if an earthquake occurs.
