Vulnerability Assessment of Reinforced Concrete Building Post-Earthquake

Some earthquakes that occurred recently, such as the earthquake in Aceh, Padang, Yogyakarta, and in other areas have been many casualties, loss of property, as well as damage to reinforced concrete buildings. Seeing this situation, especially in Indonesia, region frequent earthquakes, a guideline of vulnerability assessments needs to be proposed. This paper presented the evaluation of the vulnerability of reinforced concrete buildings against earthquake loads. In support of this study, it was necessary to collect data from a case study before damage occurred and the observation conditions after earthquake of the buildings. Previous studies have been conducted a testing of a case study by providing lateral loads of a building to simulate the earthquake loads. The testing was intended to obtain some type of damage from each step of the loading. This study was conducted to find out the behaviour of damage and deviation that occurred in the case study based on a numerical analysis. Comparing the testing and numerical analysis of the buildings, the analyses were used to make a recommendation whether the building was still in a state of Immediate Occupancy, Life Safety, or Collapse Prevention. The results showed that a proven of assessing visually of the building was agree with the numerical results. This study also made vulnerability assessment forms after earthquakes and a justification of the assessment for reinforced concrete buildings.
