To study the behavior a deck when it was collide with the ship approaching to the deck to berth, it was analyzed the effect zone by the ship collision which consists of deck slab and PC piles of the quay. The numerical technique is used to simulate the behavior of the deck when the ship hit the expansion joint of deck between the deck slabs. The failure behavior and zone of the deck are determinated by the comprehensive numerical study. The impact energy by the ship is also evaluated. It is concluded that these numerical analysis gave a reasonable estimation of the remedial area of the deck damaged by ship collision.

Use of Ultra-sonic test for checking concrete integrity has increased in recent years. In order to test or check the Quality of the cast in place concrete piles, two main types of non destructive integrity tests such as sonic integrity, sonic logging are usually employed. Sonic integrity test is the most common method in integrity test on piles. Sonic logging test in occasionally employed as a part of pre-planned site. This paper presents a full-scale model test results of these two commonly used non-destructive tests on the cast in place concrete piles.

“○○~○○간”에 건설된 철도교로 공사 중지로 인해 10년 이상 방치된 상태이나 최근 공사 재개로 기존 구조물에 대한 정밀안전진단을 통해 구조물 유용여부를 판단하고 이에 따른 보수 · 보강 방안을 제시하는 것으로써 시설물 내하력 평가시 레일 미시공으로 인해 열차 재하가 불가하여 재하시험전 선행 구조해석을 통해 열차 재하시와 유사한 25t 덤프트럭 2대(총중량 80ton)를 동시 재하하여 공용내하력을 평가하였으며, 변경된 시방규정을 만족시키기 위한 하부 구조 및 기초 보강 방안을 제시하였다.
