Abstract
It is urgently necessary to achieve seismic retrofit of energy-related facilities in waterfront area against large-scale earthquakes in the near future, such as Nankai Trough earthquake and Tokyo inland earthquakes. During earthquakes the following requirements are needed in an open-type wharf with marine loading arms; 1) reduction of acceleration response to prevent damage to loading arms, 2) reduction of displacement response to prevent damage to piping, 3) prevention of damage of steel pipe piles to keep stability of a wharf. To satisfy these requirements, an application study of buckling-restrained braces has been carried out. It has been found that effective damping effect is obtained by placing the buckling-restrained braces between the wharf and new foundations whose horizontal rigidity is higher than the wharf.
