000020152 520__ $$2eng$$aMethods for designing coastal parapet levees have not yet been developed for design seismic ground motion based on the Japanese design standard for port facilities, and no systems that consider the levees’ dynamic characteristics have been built. This study used model testing and numerical analysis to establish a method for evaluating coastal parapet levees’ seismic performance taking their dynamic characteristics under earthquake loads into consideration. Model tests using a shaking table were performed to examine the parapet levees’ seismic responses to various design ground motions. Then the Fourier spectral ratios from the response accelerations of the ground surface and the structure were calculated to examine the levees’ frequency characteristics. The acceleration response spectra at the ground surface were calculated to estimate the structures’ maximum response accelerations. In addition, horizontal loading tests were conducted to verify the validity of the method of calculating natural frequencies. Seismic response and structural analyses were performed based on the configurations of the model tests. The applicability of the method for designing parapet levees was verified by comparing the results of the model tests and the numerical analyses.
