PERFORMANCE-BASED DESIGN IN EARTHQUAKE GEOTECHNICAL ENGINEERING, FROM CASE HISTORY TO PRACTICE, TSUKUBA, JAPAN, JUNE 15-19, 2009 1 INTRODUCTION 1.1 Project Description The development of Kish free economical zone re- quires the development of the Kish commercial port in this Island. Figure 1 shows the general view of Port and Island, sited in the south of Iran in Persian Gulf. Figure 1. Kish Commercial Port Location in the north-east of Kish Island, Iran. Kish Commercial port has 13 active quay wall posts and one part of the port development is construction of 4 new quay walls for 12000 DWT, 2000 DWT general cargo and 12000 DWT and 35000 DWT container ships. Location of exist and development posts are illustrated in Figure 2 and characterization of the development quays are summarized in Table 1. existing berthes future berthes Figure 2.

One part of the Kish Commercial Port development is con- struction of 4 new quay walls for 12000 DWT, 2000 DWT general cargo and 12000 DWT and 35000 DWT container ships (DWT: deadweight tonnage). These quays are parallel to shore line in the basin of the Kish commercial port. For selection of the quay wall type, comparison of various types' quay walls has been done and three types of quay walls containing Sheet Pile (by adjacent piles), Block Quay Wall, and Open-type wharf structure has been selected and designed. Considering the seismicity level of earthquake in the Kish, three mentioned types of quay have been designed in static condition and dynamic condition for two levels of earthquakes by pseudo static modeling of earthquakes in accordance with performance based design criteria stated in PIANC (2001).
