Considering the current situation that there is no a consensus code for seismic design of port structures to unify manage difficultly in America，American Society of Civil Engineers （ASCE） is accredited by the American National Standards Institute （ANSI） to develop ASCECOPRI 61-14 Seismic Design of Piers and Wharves on the basis of local design criterions for some existing ports. This code provides detailed provisions for seismic level，seismic performance objects，seismic design methods and seismic design and construction requirements of components，and includes the latest achievements of seismic research in the world in recent years，and it is significant to promote the development of seismic design for pile-supported wharves. In order to help domestic engineering technicians understand this code with ease，we introduce the compilation background and design philosophy，and interpret and explain each part of the code in detail combining with engineering experience. Moreover，we briefly compare the differences between this standard and domestic code，which can provide the references for the further revision of backward domestic code.
