Abstract

In this paper, we present the evaluation results for the conservatism of the response acceleration method (RAM), for seismic response analysis of box-type power cable tunnels. We studied 50 examples, considering the cross sections of 25 power cable tunnels, and two soil conditions for each power cable tunnel. A refined dynamic analysis method considering the soil-structure interaction was further employed to evaluate the conservatism of the RAM. The comparison revelated that the seismic responses computed using the RAM were consistent with those obtained using the refined method, since the averages of response ratio (defined as the ratio of the response by RAM to that of the refined method) approached 1.0, and the standard deviations of the response ratio were less than 5%. Finally, we found that applying a load factor of 1.1 to the response of the RAM allowed for a conservative design for seismic loads.

이 논문에서는 박스형 전력구의 지진응답해석에 사용되는 응답진도법의 보수성을 평가하였다. 이를 위해 25가지 전력구 단면과 각 전력구에 대한 2개의 지반조건을 고려한 총 50개 예제를 선정하였다. 응답진도법의 보수성을 평가하기 위해 동적 지반-구조물 상호작용을 고려한 정밀해석법에 의한 응답과 비교하였다. 비교결과, 정밀해석 응답에 대한 응답진도법에 의한 응답의 비로 정의한 응답비의 평균이 1.0에 근접하며, 응답비의 표준편차도 5% 이내로 매우 작아서, 응답진도법에 의한 해석이 정밀해석법과 일관됨을 알 수 있었다. 마지막으로 응답진도법에 의한 응답에 하중계수 1.1을 적용하면 전력구의 보수적인 내진설계가 가능할 것으로 나타났다.
