Abstract
It is well known that the port facilities in Kobe Port suffered severe damages during the 1995 Hyogoken-Nambu earthquake. Especially, many caisson type quay walls were damaged during the earthquake. In order to mitigate hazards and losses due to earthquakes, seismic design methodologies have been developed and revised after each past earthquake event. The design practice of port structures in Japan introduced a performance based design concept as a result of damage investigations after the 1995 Hyogoken-Nambu earthquake. The restoration of Kobe Port was based on following philosophies: 1) quick recovery of the functions of the port, 2) improve seismic performance, 3) renewal with change the function of facilities and 4) continued operation of the port during restore works.
