It is required seismically strengthened quaywalls, which function as crucial infrastructure for emergency goods transportation, are designed to enable the berthing of vessels even after a large earthquake disaster. To achieve this objective, the relative displacement of the quaywalls in the normal direction is necessarily controlled under a certain tolerance level following an earthquake. However, the existing seismic design approach primarily focuses on residual displacement in a single representative crosssection, thus not directly assessing the relative displacement in the direction of the quaywalls. This study proposes a method for developing a ground response reduced order model with a minimum experimental design, which can be applied in design process in practice. Using the reduced order model, this paper also presents a probabilistic method for evaluating the relative displacement in the normal direction to the quaywalls. Finally, the effectiveness of the proposed method is verified with an example of application to an actual structure.
