Abstract
This paper discusses the damage types, repair methods and retrofitting of buildings post an earthquake. Data were taken by conducting surveys and assessment of buildings directly, both engineered and non-engineered buildings affected by the West Sumatra earthquake in 2009. Some causes of damage, among them is the detailing of reinforcement that do not follow the existing standard, soft-story effect, foundation failure, low material quality and does not meet the requirements, design and implementation of the construction do not follow the rules and technical provisions of the building earthquake resistant. Improvement and buildings retrofitting can be done after the buildings damage types or its components/parts and the quality of the building materials used were known. The structural analysis was done in order to know the cause of the building elements damaged and if the results of analysis with the latest regulations earthquake load, the building structures is able to withstand the earthquake loads and a repair is not required, but if not, the retrofitting is required.
Highlights
Earthquake disasters could cause many buildings to be damaged and may collapsed
Indonesia has not had a standard in damage assessment, repair and retrofit the damaged building post earthquake
Civil engineering buildings could be grouped into non-engineered building and engineered building
Summary
Earthquake disasters could cause many buildings to be damaged and may collapsed. Many of the damaged buildings are to be destroyed based on the advice of experts, consultants or stakeholders, while the buildings could still be repaired and be retrofit so that the buildings can be reused (Ismail et al, 2011, 2014). To destroy the damaged buildings after an earthquake is an easy decision, but not supported by adequate data. The main advantages of repairs and retrofit the damaged buildings after earthquake will be save time and money (Ismail et al, 2011, 2014). At West Sumatra earthquake of 2009, a ten years ago, many buildings were damaged, both non engineered building and engineered building
