5、enges; new details and practices for the design and construction of wharves were developed and followed by new codes and guidelines for port structures. This work, however, was driven by different authorities, often not closely coordinated: Code Writing Authorities, Owners (Ports), and Consultants.

6、As a result of the rapid development in this field, the resulting documents for the seismic design of wharves made their interpretation sometimes difficult. POLB recognized the need for uniform and port-specific guidelines and developed port specific Wharf Design Criteria. This paper specifically addresses the Seismic Design Criteria. They include Ground Motions and Performance Criteria, Geotechnical Considerations with particular attention to soil-stru
