| Summary | Published in June 2003 IOT SERIAL No.92-69-748，228pp. The major object of seismic resistant performance-based design is to assess the allowable capacity (including deformation, ductility, stress and strain) of harbor structure under the earthquake. So in this study, we will first moderately define and classify the force of design earthquake. Then, we will properly define the relative structural damage degree and allowable damage level. As the third step, we will establish the assessment module that can satisfy the analytic capacity of structural seismic resistant performance-based design, so that we can estimate if the structural performance satisfies the demand in use. Up to now, the design specification of harbor structure is based on the working stress design method. However, due to increasing knowledge about the structural behavior of reinforced concrete and steel members, it is a common trend to adopt the strength design method. Therefore, the first year of this project is aimed at a evaluation of the design of harbor structures based on the strength design method. In the second and the third years, we will aim at a evaluation of the performance-based design on the harbor structures. As the first year of this project, we had completed literature collection and analysis. Then, with the assistance of experienced engineers, the results were compared with the Japanese design specification of harbor facilities. We evaluated the magnitudes of various load factors applied in domestic harbor structures based on the strength design method. However, the survey and statistics on the member strength and loading of domestic harbor structures are still unavailable. We cannot evaluate the magnitudes of various load factors by probability theories. Therefore, we suggest the engineering society should pay more attention to the survey and statistics about the harbor structures in the future. |
