The reasonable pile connection to superstructure ensures especially in the seismic design of the wharf not only force transmission effectively between the pile and superstructure,but also exertion of structure displacement capacity which forms protection of superstructure.Although the Chinese standard about pile foundation lists the relevant requirements of steel pipe pile connection to superstructure,but it doesn’t mention specific calculation methods and design requirements under the seismic load.In this essay,several steel pipe pile connections to superstructure in seismic design are discussed.
