Open-type quaywall with sheet pile wall anchored by forward batter piles, which is constructed with an open-type wharf built in front of sheet pile wall, is used for not only newly built structures but also reformation. Reliability-based design has been adopted in the 2007 edition of technical standards for port and harbor facilities. However, the design method of this type is not specified. Therefore, we examined its seismic coefficients and partial factors for level-1 earthquake ground motion. We have found that the performance requirement for sheet pile quaywall and open type quaywall are satisfied by following method: 1) seismic coefficient of sheet pile wall part shall be calculated by the equation for sheet pile wall with vertical pile anchorage, 2) piled pier part including sheet pile wall shall be designed by frame analysis using partial factors for open-type quaywall on vertical piles.
