기존 철도 교량의 내진성능 평가

This is the basic study on the evaluation of seismic performance for existing railway bridges. This study presents an evaluation items and a progressive method of seismic performance for existing railway bridges. In the evaluation of seismic performance, a two-stage is used. Firstly, according to the seismic performance evaluation categories, preliminary screening of bridges is recommended. And using the seismic rating system, seismic rank of bridges is calculated. Secondly, for the selected bridges in the first stage, detailed evaluation is recommended.
