Abstract

As vertical extension remodeling policy was implemented in 2014, Safety Inspection Manual was established to ensure structural safety during the vertical extension remodeling. In the manual, the story weight for capability evaluation was based on the Safety Inspection Manual for Reconstruction. Although capability evaluation in the vertical extension remodeling is more important than reconstruction, engineering basis for the story weight is insufficient. Therefore it is necessary to improve the method of calculating the story weight. In this study, story importance and story weight were defined through the case analysis of capability evaluation in order to provide engineering basis for story weight. Also, new story weight equation was presented considering the load-bearing ratio of structural members.

2014년 수직증축형 리모델링 제도가 시행됨에 따라, 수직 증축과정에서 발생 가능한 구조 안전에 대한 문제 해결을 위해 증축형 리모델링 안전진단 매뉴얼이 제정되었다. 이 매뉴얼에서 내하력 평가를 위한 층별 가중치 부분은 재건축 안전진단 매뉴얼을 인용하였으나, 공학적 근거가 다소 미흡하다. 또한, 수직증축형 리모델링에서 내하력 평가의 중요도가 재건축에서보다 높으므로 층별 가중치 산정 방법의 개선이 필요하다. 따라서 본 연구에서는 층별 가중치에 대한 공학적 근거를 마련하고자 기존 매뉴얼 및 지침 분석을 통해 층별 중요도와 층별 가중치를 정의하였으며, 역학적 원리를 바탕으로 합리적인 가중치 산정식을 제시하였다.
