건축구조기준 2016 기반 강풍 취약도 평가 방법론 개발

Abstract

This paper presents a methodology to assess extreme wind fragility and vulnerability in the probabilistic domain based on KBC (Korean Building Code) 2016 for the first time in South Korea. In this study, wind load equation is derived based on KBC 2016 to consider the effects of 3-second gust wind speeds. Wind load related statistics is also proposed for the derived wind load equation based on related literature. A probabilistic analysis model is developed to assess extreme wind fragility and vulnerability by Monte Carlo Simulation method. The reliability of the proposed methodology is verified with the results of other fragility and vulnerability assessing methodologies based on ASCE (American Society of Civil Engineers) wind provision for roof sheathing panel system of a low-rise prototype building. This study shows that extreme wind fragility and vulnerability of buildings can be assessed using the wind load equation in KBC 2016 and confirms that the wind fragility and vulnerability by the proposed methodology agree well within small error ranges compared with the results of existing methodologies based on ASCE wind provison. The proposed methodology presented in this study can be used as a method for establishing extreme wind fragility or vulnerability when loss estimations are needed for the natural disaster reduction plan, etc.
