| Abstract | In this study, loss in terms of monetary losses and casualties due to building damage subjected to different levels of ground motion is conducted for Bangkok Metropolitan area. The methodology and framework for estimations are based on the proposed in ATC-13 that presents the engineering methodologies and necessary data for the earthquake damage and loss assessment in California. To estimate damage and loss, it consists of 4 major parts: (1) predicted values of peak ground acceleration (PGA) or levels of earthquake intensity including the amplification of soil properties, (2) building inventories, (3) motion-damage relationship models, and (4) casualty models. For PGA values, they are obtained from the previous study of a seismic hazard investigation for Bangkok. Motion-damage relationship and casualty models are adopted directly from ATC-13 due to the lack of past statistic data to generate the reliability models for Bangkok. This study focuses on the part of building inventories because it is the important part that has never been developed yet. To generate a comprehensive inventory database, several data sources are reviewed. Most available data are not complete and not in usable formats . Therefore, this study presents the methods and procedures for classifying types of data as well as combining them from various sources. In these processes, some assumptions and judgement are also used in order to develop a complete regional inventory as much as possible. After obtaining the suitable building inventories, loss can be conducted. The results show considerable values of monetary losses and casualties. For the least damage case of possible event at MMI 7, there are about 500 deaths, 2,000 serious injuries, and 15,000 minor injuries. Monetary losses are about 0.892 trillion bahts. For the worst case at MMI 10, monetary losses are about 5.941 trillion bahts with 40,000 deaths, 160,000 serious injuries, and 1,200,000 minor injuries. It is important to note that these evaluated results tend to be under estimate because the used models of motion-damage relationship and casualty are adopted from ATC-13 that conducts these models for the structures designed for seismic resistance where as buildings in Bangkok were not. |
