Abstract

This paper introduces a series of tools for a rapid yet reliable visual multi-hazard vulnerability prioritization of school infrastructure against potentially destructive natural hazards, i.e., earthquake, typhoon, and flood. The proposed tools can assist and speed up the process of identifying the most vulnerable school buildings for further decision-making. For each considered school, a set of parameters, including general information on the building and its occupants, structural and nonstructural characteristics, and secondary vulnerability modifiers, are first gathered. For each parameter, a vulnerability rating is assigned to its possible attributes, finally determining a vulnerability index for each considered school building exposed to earthquake, wind, and flood hazards. A mobile application has been developed for the entire process to assist the surveyors by increasing the efficiency and speed. The applicability of the proposed methodology and mobile application is tested by conducting an assessment of 115 elementary schools located in the city of Cagayan de Oro, Philippines. A statistical analysis of the gathered data along with the estimated vulnerability indices, allow the identification of the most vulnerable school buildings for more detailed structural analysis, and retrofitting/strengthening planning and conceptual design.
