본 논문에서는 실패한 구조물에 초점을 맞추어 조사를 진행하였다. 실패한 구조물은 구조적, 역학적, 환경적 부정합으로 인해 구조물이 붕괴된 경우로 인명 피해가 발생한 것으로 정의하였다. 삼풍백화점과 성수대교의 국내 사례와 방글라데시 라나 플라자, 미국 미시시피 강 교량의 국외 사례를 통하여, 각각의 붕괴사고의 원인을 규명하였으며, 붕괴사고의 해결책을 모색하고 체계적으로 분석하였다. 본 연구를 통하여 구조물의 붕괴 뿐 만이 아니라, 다방면의 재난을 예방 및 방지할 수 있는 연계 시스템의 확립 또한 강조하였으며, 사고방지를 위해 변화하는 시방서 및 기준에 대하여도 언급하였다.

Since the 21st century a free-form building has been noticeably constructed. Now the definition "the monumental architecture is a free-form one." has come to be established. As a free-form building became a landmark of the city and a factor rising a value of the building all around the world, it is currently required to consider a more efficient design process. Therefore this research aims to learn approaches of the lasting free-form design process by considering the design process of Dongdaemun Design Plaza(DDP) designed by 'Zaha Hadid' that is a typical free-form building of Korea and the correlation between the design in the conceptual stage and the BIM(Building Information Modeling) design in practical stage.

The Dongdaemoon complex stadium is scheduled to remodelled into an international park, which will be named Design Plaza. The Dongdaemoon baseball field was constructed with Rahmen Structure which comprised beams, slabs and columns. In order to assure for viewing, the stadium was composed unusual structure that the height of the front column and the back column was designed differently. The bleachers was an upper arch form for viewing. The slab was not flat unliked the general infrastructure and tilted in stairway type for viewing. If we had applied the mechanical demolition method, we could have predicted several problems. Firstly, the stand could be unstable when the heavy equipment was to crush the reinforced concrete on the slab. Because the slab was not flat. Secondly, the construction expense and construction duration could be increase when the large equipment was to crush the reinforced concrete on the ground. Because the height of the stand was too high to crush on the ground so it needed to build a filling. Thus, we applied both the mechanical demolition method and explosives demolition method at the design stage. The result of explosives demolition was of complete success in terms of structural movement and controlled blasting noise and vibration. This case study provided a good example for a successful application of explosives demolition in urban areas.
