Abstract

This study proposes a new approach, Applied Element Method (AEM), to analyze the progressive collapse of structures due to impact and blast, and verifies its reliability. The AEM method focuses on quantitatively analyzing the mechanism of progressive collapse by integrating the characteristics of the impact and blast, and the mechanical response of the structure. The analytical performance of the AEM is evaluated by comparing the results with the results of exact solution or FEM based on various models for static, dynamic, linear, and nonlinearity. The results show that the AEM method has high accuracy and reliability in predicting structural damage due to impact and blast, and thus can be established as a useful tool for structural safety assessment and design.

본 연구는 폭발로 인한 구조물의 연쇄붕괴를 분석하기 위해 새로운 접근법인 AEM(Applied Element Method)을 제안하고, 이 방법의 신뢰성을 검증하였다. AEM 방법은 폭발의 특성과 구조물의 기계적 반응을 통합하여 연쇄붕괴의 메커니즘을 정량적으로 분석하는 데 초점을 맞추었다. 정적, 동적 및 선형, 비선형에 대한 다양한 모델을 기반으로 그 결과를 수계산 또는 FEM결과와 비교하여 AEM의 해석적 성능을 평가하였다. 분석 결과, AEM 방법은 폭발에 의한 구조물 손상의 예측에서 높은 정확성과 신뢰성을 보였으며, 이를 통해 구조물 안전성 평가 및 설계에 유용한 도구로 자리 잡을 수 있음을 확인하였다.
