Recently, advanced countries assessment the risk of fire to prevent large-scale damage to high-rise buildings, In addition, performance-Based design, which is a fire risk assessment, is being conducted in Korea to prevent massive damage to high-rise buildings. However, unlike advanced countries, fire risk assessment in Korea is subject to fire risk assessment only for objects subject to consent from fire-fighting facilities such as building permits, When building engineers and fire-fighting engineers assessment the risk of fire, It has always been discussed because the results vary depending on which part of the evaluation is focused between economic feasibility and safety. Therefore, in this study, we would like to propose a fire risk assessment process suitable for domestic conditions by comparing the process of performance-based design, which is a domestic fire risk assessment, and the process of Iso/TC 16732 which is an overseas fire risk assessment.

이 논문에서는 터널막장 주변지반의 3차원적 지반거동을 고려한 인접건물의 손상위험도 평가시스템 개발에 관한 내용을 다루었다 이 시스템은 크게 건물 및 지반정보 모듈, 계측데이터 모듈, 침하평가모듈 및 건물 손상평가모듈로 구성되어 있다. 지반 침하평가 및 건물 손상평가 모듈은 이 시스템의 핵심 모듈로서 Attewell 등(1982)이 제안한 침하평가 모형을 토대로 터널시공으로 인한 침하량 및 범위를 정량적으로 평가한 후, 터널노선에 인접한 건물의 손상위험도를 Mair 등(1996)이 제시한 건물손상 평가방법을 근거로 평가한다. 터널굴착으로 인한 지반거동 평가에서 가장 큰 영향인자인 지반손실률($V_{s}$)또는 최대침하량($w_{max}$)및 변곡점(i)의 위치는 계측자료, 수치 해석 결과 그리고 각종 경험식을 사용하여 자동적으로 계산되도록 구축하였다. 한편, 건물 손상평가는 터널막장의 위치를 변화시키며 임의 구간의 인접건물에 대한 손상위험도 평가가 수행될 수 있는 기능을 부여하였다. 개발된 시스템 검증은 Boscardin과 Cording(1989)이 워싱턴 DC의 매트로 터널에 인접한 2층 조적식 건물의 계측사례를 적용하여 수행하였다.

This study proposes a methodology for the regional seismic risk assessment of structural damage to buildings in Korea based on evaluating individual buildings, considering inconsistency between the administrative district border and grid lines to define seismic hazard. The accuracy of seismic hazards was enhanced by subdividing the current 2km-sized grids into ones with a smaller size. Considering the enhancement of the Korean seismic design code in 2005, existing seismic fragility functions for seismically designed buildings are revised by modifying the capacity spectrum according to the changes in seismic design load. A seismic risk index in building damage is defined using the total damaged floor area considering building size differences. The proposed seismic risk index was calculated for buildings in 29 administrative districts in 'A' city in Korea to validate the proposed assessment algorithm and risk index. In the validation procedure, sensitivity analysis was performed on the grid size, quantitative building damage measure, and seismic fragility function update.

A GIS-based tunnelling risk management system (GIS-TURIMS) has been developed in this study The developed system uses ArcView 8.2 as a basic platform and the built-in interface(VBA) has been used to perform first-order simplified analyses for prediction of tunnelling-induced ground movements and building damage assessment. The main emphasis in this study was to develop a working framework that can be used in the perspective of tunnelling risk management. The developed system is capable of carrying out computationally intensive first-order analyses for ground movement prediction as well as building/utilities damage assessment with fully taking advantage of the GIS technologies. This paper describes the concept and details of the GIS-TURIMS development and implementation.

A substantial portion of the cost of deep excavations in urban environments is devoted to prevent ground movements and their effects on adjacent buildings and utilites. Prediction of ground movements and assessment of the risk of damage to adjacent structures has become an essential part of the planning, design, and construction of a deep excavation project in the urban environments. This paper presents damage assessment techniques for buildings and utilities adjacent deep excavation, which can be readily used in practice.

도심지에서의 지반굴착은 배면지반의 변위와 그에 따르는 건물의 손상을 유발시킨다. 굴착에 의한 지반변위의 예측과 굴착면 주변에 위치한 건물의 손상 위험도 평가는 설계단계에서 필수적인 요소이다. 본 논문에서는 기존의 굴착에 의한 지반변위 예측기법인 Peck의 방법과 Bowles의 방법을 조합하여 지보굴착에 따르는 배면지반 변위예측방법을 제안하였다. 또한, 배면지반의 Green-field 뒤틈각과 수평변형률을 이용한 인접건물 손상위험도 평가기법을 제안하였다. 이 기법은 싱가폴에서 시공중인 대규모 지반굴착공사의 설계에 성공적으로 적용되었다.

During deep excavation, changes in the state of stress in the ground mass around the excavation and subsequent ground losses inevitably occur. These changes in the stress and ground losses are reflected on surrounding ground in the form of ground movements, which eventually Impose strains onto nearby structures through translation, rotation, distortion, and possibly damage. A substantial portion of the cost of deep excavations in urban environments is, therefore, devoted to prevent ground movements. Prediction of ground movements and assessment of the risk of damage to adjacent structures has become an essential part of the planning, design, and construction of a deep excavation project in the urban environments. This paper presents excavation-induced ground movement characteristics as well as important issues related to excavation-induced building damage assessment.

The purpose of evaluating the fire risk of a building is to predict damage or loss of life and property in unspecified circumstances and to minimize expected damage. The fire risk assessment for buildings in Korea analyzes fire risk according to performance-oriented design under the Enforcement Decree of the Fire Facilities Act and the Fire Causing Index under the Enforcement Decree of the Multi-Use Business Act. Fire risk analysis is mainly conducted by using fire statistics or analyzing the results of safety inspections of buildings. In the case of fire statistics, it is necessary to analyze the fire risk in consideration of the degree of fire damage in each number of fires, as all fires received by the fire department are collected. In addition, it is necessary to devise fire safety measures for buildings by predicting the number of casualties that may occur due to fires in each building. Accordingly, this study aims to analyze the characteristics of casualties by building use using the number of fires judged to have grown.

This study aims to recognize damage indicators of typhoon and to develop damage function's indicators, using information derived from the actual loss of typhoon Maemi. As typhoons engender significant financial damage all over the world, governments and insurance companies, local or global, develop hurricane risk assessment models and use it in quantifying, avoiding, mitigating, or transferring the risks. For the reason, it is crucial to understand the importance of the risk assessment model for typhoons, and the importance of reflecting local vulnerabilities for more advanced evaluation. Although much previous research on the economic losses associated with natural disasters has identified the risk indicators that are indispensable, more comprehensive research addressing the relationship between vulnerability and economic loss are still called for. Hence this study utilizes and analyzes the actual loss record of the typhoon Maemi provided by insurance companies to fill such gaps. In this study, natural disaster indicators and basic building information indicators are used in order to generate the vulnerability functions; and the results and indicators suggest a practical approach to create the vulnerability functions for insurance companies and administrative tasks, while reflecting the financial loss and local vulnerability of the actual buildings.
