Abstract

The fragility of the old window systems need to be evaluated to expect damage levels because they were generally designed based on experiences without specified engineering procedures. The probabilistic resisting capacities of the old window systems are required to perform fragility analysis. Firstly, the types of old window systems were investigated to classify size, material, structural systems, etc. The structural components of each window system are classified and their resisting capacities are evaluated through structural tests or using previous experiment results and specifications. Finally, the probabilistic resisting capacity of each window type is evaluated by the Monte Carlo simulation. By summarizing the evaluation results, the probability parameters of resistances for old window systems are provided for the fragility analysis.

구형 창호 시스템의 취약성은 일정한 공학적 설계 과정 없이 경험에 근거하여 설계하였기 때문에 위험 수준을 예측할 수 있는 저항 성능을 평가할 필요가 있다. 취약성 분석을 수행하기 위해서는 구형 창호의 확률적 저항 성능이 평가되어야 한다. 우선 구형 창호 시스템을 사전 조사하여 창호 크기, 재료, 구조 시스템 등을 분류하였다. 각 창호시스템의 구조 요소를 분류하였으며, 기존 문헌 자료 또는 실험을 통하여 각 요소의 저항 성능을 평가하였다. 최종적으로 몬테카를로 시뮬레이션 방법을 사용하여 구형 창호 시스템 별로 확률적 저항 성능을 평가하였다. 평가 결과들로부터 구형 창호의 확률 요소 값들은 취약성 분석을 위해 제공된다.
