Abstract
The present study aims at presenting the earthquake resistant evaluation method for pile-supported wharves. For the purpose, frequency characteristic of pile-supported wharves was evaluated with strong-motion array observation and microtremor observation at Yokohama Port and Kawasaki Port. Natural periods and seismic coefficients of the wharves obtained with observation were compared with those assumed with present design code. Moreover, two-dimensional earthquake response analyses taking into account the effect by the access bridge between the superstructure of the wharf and the retaining wall were conducted. Necessity for modeling the access bridge was verified and earthquake resistant evaluation method was proposed.
