Disaster Preparedness Assessment Tools of Structural Performance for Indonesian School Buildings

Abstract

It has been recorded so far that the earthquake in Indonesia has damaged many publicfacilities and claimed many victims. Most cases of casualties were not caused directly by the earthquake but as a result of falling debris from buildings that were unable to respond to the earthquake. To avoid similar incidents in the future, all buildingsin Indonesia need to be inspected and ensured that they are safe from the threat of an earthquake, and school buildings are no exception. The absence of a specific assessment tool for earthquake-resistant school buildings underlies this research. The assessment tool was developed based on the results of a literature review of several building inspection standards in various countries. Several research variables that were previously identified were then validated and processed using the Analytical Hierarchy Process method. Some experts in related fields were involved in the process to formulate the significant variables, the respective weights as well as scoring systems. This research produced a preliminary assessment tool in two parts. The first one, which emphasizes examination by visual method, is translated into four new categories: Building Slope Inspection, Sub-structure Component Inspection, Upper Structure Component Inspection, and Document Inspection, with 12 sub-categories and 28 indicators. Meanwhile, the second part emphasizes on the non-destructive testing as additional scores. It includes three types of tests for concrete and two tests for steel materials. Finally, the level of preparedness for the structural components of a good school building needs to meet a minimum score of 70.
