Seismic Risk Assessment for Architectural Heritage considering Historical Data

Abstract

The disaster prevention researches about seismic hazard has significantly increased due to huge casualty of human-beings and property damage since the 2010 earthquake in Haiti and the 2011 earthquake in Japan. Although the occurrence of earthquake is relatively low in Korea, preparation is required due to increase frequency and scale of earthquake. However, available researches on earthquake prevention are mainly focused on modern architecture involved in Casualties. This research is focused on earthquake disaster. Earthquake characteristic is unpredictable and damage of earthquake widespread and destructive. So most countries located in earthquake hazard area protect building, infrastructure and life. In Korea, It is located in adjacent areas of plate boundary that is dangerous area about earthquake. That`s why protection about earthquake is needed in Korea. Architectural heritage have a lot of benefits such as historical value and academic value. That`s why It should be preserved from any dangerous factor especially natural disaster. In Korea, preparations for earthquake are only focused on building and infrastructure and research scope on the prevention of architectural heritage is yet to be reached. Effective preparations against earthquake build system. It helps manage process because of lack of manager. So this research is proposed risk assessment process and system framework for effective preparations. In this research, seismic risk assessment and building system for management of architectural heritage is aimed. Seismic risk of architectural heritage was calculated using a data from soil investment and a fatigue factor calculated by historical earthquake data and maintenance records both from architectural heritage. Seismic risk is suggested on the basis of four levels, and system for managing architectural heritage about earthquake through GIS is built.
