Abstract
교량의 내진성능을 파악하기 위해서는 대상 교량에 대한 내진성능평가 및 수치해석을 통해 검토하는 것이 일반적이다. 내진성능평가 및 수치해석을 통한 검토는 특정 대상교량에 대한 분석 방법으로 전국 교량을 관리하는 각각의 관리주체에서 이를 수행하기에는 많은 문제가 발생할 수 있다. 따라서 본 연구에서는 다양한 형식 및 특성을 지니고 있는 공용 교량에 대한 내진성능을 추정할 수 있도록 연구를 수행하였다. 내진성능 추정은 지진위험도평가 방법을 적용하였으며, 교량의 형식 및 제원에 대한 지진취약도 곡선을 산정하고 국내 내진설계기준을 적용하여 공용 중인 교량의 내진성능을 추정하였다. 또한 이를 플랫폼에 탑재하여 사용자가 국내 교량에 대한 내진성능 추정을 간편하게 검토할 수 있도록 서비스 항목을 구축하였다.
In order to understand the seismic performance of a bridge, it is common to review through seismic performance evaluation and numerical analysis of the target bridge. Seismic performance evaluation and review through numerical analysis are analysis methods for specific target bridges, and many problems can arise in each management body managing bridges nationwide. Therefore, in this study, research was conducted to estimate the seismic performance of public bridges with various types and characteristics. Seismic performance was estimated by applying the seismic risk assessment method, calculating the seismic fragility curve for the type and specifications of the bridge, and estimating the seismic performance of the bridge in use by applying the domestic seismic design standard. In addition, by installing it on the platform, service items were established so that users can easily review the estimation of seismic performance of domestic bridges.
