It is noted that the disaster such as fire, explosion, collapse has been rapidly increased caused by strength deterioration of steel structures at petrochemical plant during fire. In this regard, it is stressed out that the legal requirement for fire proofing for steel structures at petrochemical plant should be carefully reviewed since the current legal requirement such as Industrial Safety & Health Law, Architectural Law has a conflict and different way of approach. In addition, it is our point of view that the present law should be revised to consolidate into single law including engineering design criteria to reflect unreasonable legal requirement. It is further our point of view that the performance certificate for fire proofing like UL-1709, basis of maintenance should be appropriately and reasonably provided in line with global practice.

이 연구에서는 플랜트 지하구조물의 상태평가를 위해 국내외 기준을 확인하고 플랜트 지하시 설의 핵심평가 요소 도출을 통하여 향 후 플랜트 지하구조물의 상태평가를 위한 기초 자료로 활용하고자 한다.
