A Simulation of Deformation of Rubble Structures based on the Stochastic and Dynamic Theory

In order to construct an economical and reasonable structure, design methods, which can take economical efficiency into consideration, is necessary. The performance based design that specifies the performance of a structure is one of the economical design methods. An economical design would be established by allowing deformation of a structure within limits which satisfy the performance demanded. Therefore, the deformation of a structure should be estimated quantitatively. A probability which the deformation occurs should be evaluated also. Conventionally, this is done by hydraulic model tests. The model tests, however, have scale effects, and they might be expensive. Accordingly, the development of the numerical computational method for the deformation is useful for the performance based design. One of the coastal and maritime structures with the higher applicability for the performance based design night be a rubble mound structures, such as a sloping breakwater, an artificial lead, or a rubble submerged breakwater. Two prediction methods of deformation for rubble mound structures were developed in this study. One is a deterministic method, and the other is a stochastic method. A deterministic method is consisted of fluid analysis and distinct element analysis. The stochastic method is an approximately method which expanded the deterministic method based on the reliability theory. The methodology and the applicability of two methods are investigated in this study.
