Key points about ASCE standard Seismic Design of Piers and Wharves（ASCE/COPRI 61-14）are expounded.This standard has the following characteristics:1)The design classifications of the high,moderate and low are prescribed according to the importance of piers or wharves to the regional economy and the necessity of post earthquake recovery;2)The operation level,contingence level and design earthquake are used for the seismic design;3)In addition to the force-based design method,it also provides a displacement-based design method;4)The capacity protection idea is introduced to reduce the damage to the piers or wharves during the earthquake.The advices for developing the seismic design methods of port in China are put forward based on the current domestic and foreign codes.
