Abstract
Seismic design of pile-supported wharves against the level-one earthquake ground motion is carried out by pseudo-statics using the seismic coefficient calculated with the natural period of piled wharf and the acceleration response spectrum at vertual fixed point of the piles. Meanwhile dynamic analysis is also employed, taking into consideration for the dynamic interaction of piles and ground. The response behaviors of pile-supported wharves with the pseudo-static and dynamic analyses are compared in this paper. As the result, it is clarified that discrepancy in of subgrade reaction and the damping factor in the pseudo-static and dynamic analyses causes the difference in the response behaviors of the piled wharf. The behaviors with the pseudo-static and dynamic analyses correspond, resolving the discrepancy.
