Abstract
On March 20th, 2005 an earthquake with a magnitude of 7.0 struck the port of Hakata in the northern Kyushu. A design seismic force of the earthquake motion is estimated 0.2 while the present design seismic force is 0.05 for a many of facilities at the port. The damage has been found throughout the port.
This paper presents a comprehensive review of damage of Hakata port. The facility damage is analyzed in terms of structural design, construction age and level of availability of the facility. As the result, the facility displacement has a close relationship with the structural design. An occurrence of apron holes is resulted in the structural design and the construction age. This study also shows that the damaged facilities over 30cm displacement and 10% of apron hole are out of use.
