요약

오늘날 인간의 삶의 질 향상과 다양한 욕구를 충족시키기 위한 건축물은 대형화, 고층화, 심층화, 복합화 되는 추세이며, 이에 따른 비정형화된 공간이 새롭게 창출되면서 성능위주설계대상도 증가하고 있다. 성능위주설계의 피난안전성 평가는 ASET과 RSET를 산정 비교하여 RSET이 ASET를 초과하지 않도록 하여야 한다. 그러나 지하 주차장과 같이 구획된 공간의 면적이 넓고 피난경로가 다양한 경우 현재 시행되고 있는 성능위주설계 평가 방법만으로 모든 피난경로에서 안전성을 확보하기 어려운 문제가 있다. 따라서 본 논문에서는 이러한 문제점을 극복하기 위해 현재 사용되고 있는 성능위주설계의 시뮬레이션 설정방법에 대해 먼저 고찰한 다음 지하 주차장을 대상으로 화재시뮬레이션 2가지와 피난시뮬레이션 3가지 경우를 각각 수행하여 6가지 경우에 대한 피난안전성 평가를 실시하고 비교 평가하여 문제점을 살펴보고 개선된 성능위주설계의 피난안전성 평가 방안을 제시한다.

Abstract

Today, building constructions are becoming larger, higher, deeper, and complex to improve quality of human life and meet various needs. As a result, new design space for non - typically standardized space has been created, and targets for performance-based design are also becoming increased. An evacuation safety evaluation of performance-based design should be compared with ASET and RSET estimation so that the value of RSET does not exceed the value of ASET. However, there is a problem that it is difficult to secure the safety with using the performance-based design evaluation method currently in use, especially in case of the underground parking lot, because it has wide compartment area and various routes for evacuation. Therefore, in order to overcome these problems, this paper first investigates the simulation setting method of the performance-based design that is currently in use, and then conducts two fire simulations and three evacuation simulations for underground parking lots each time, so performs the evacuation safety evaluationin total six cases of situations. Here this paper analyzes the problem with comparative evaluation research and suggests the better solution for improved evacuation safety evaluation of performance-based design.
