The inertia force acting on open-type wharves on vertical piles changes according to the natural period of the wharves. The natural period also changes according to the section modulus of the piles. This means that an iterative calculation is needed in the design of the wharves and an effective method is desirable to reduce the number of iteration.
In this study, we conducted the optimal design of the wharves using the conjugate gradient method. It was shown that the number of iteration can be reduced focusing on the shape of the response acceleration spectrum.
