Rapid Visual Screening(RVS)for School Buildings after Earthquake in Lombok,West Nusa Tenggara,Indonesia

摘要

This study discusses the results of the rapid assessment of school buildings in Lombok after an earthquake occurs.The earthquake in July 2018 with a high enough intensity caused a lot of damage to the building.The earthquake including the school building affected the entire area of Lombok Island.This study assessed 15 school buildings on Lombok Island.School samples were taken randomly from several districts that were rocked by the earthquake.The results showed that school buildings in all locations were part of a Non-Engineered Building where there were no results of analysis of earthquake resistant buildings.Overall,the condition of the building is categorized as being moderately damaged with non-structural components such as walls not having good connections with columns and beams.In addition,the structure and attributes of the roof are also damaged by a high percentage.In some buildings,it still does not follow good structural rules so that it is very dangerous for building users in the event of a large earthquake.Improvements using the retrofitting method are one of the most recommended ways to improve the performance of buildings that have mild and moderate damage.
