A Generating - Absorbing Boundary Condition Applied to Wave - Current Interactions Using the Method of Fundamental Solutions

A method of using waves instead of modes for analyzing the seismic response of buildings is presented. Instead of using the general procedure of response spectra to quantify the seismic hazard of a building a wave response function is used. An important aspect of this approach is that the wave model can describe building response using only four parameters namely, the stiffness, wave speed, time delay, and normalized distance and are shown to be enough to describe the full building response. The method presented is limited to responses due to ground motions from earthquakes and the building response to be predominately in shear. The wave analysis method proposed can be used for variable structure stiffness with uniform and non-uniform damping cases. Comparison using response spectra for a typical shear building is presented and discussed. The strength of the wave function approach is that it provides more information about the response of the specific shear buildings than the response spectra approach. As one of the findings from the analysis using waves is that the maximum strain in a shear building with variable stiffness and non-zero damping is related to the maximum velocity of the ground motion and not the maximum acceleration.

“…Loukili et al [72] have developed a wave current interaction method that uses the Numerical Wave Tank flow to carry out the predictions of computer flow. Such concept is being used in detection of vibroacoustic signatures if any damage along the pavement structure exists.…”

In situ monitoring of pavement health has been getting much attention due to the efficiency, reliability and accuracy of data. This review consists of various embedded as well as nondestructive sensing options that have been used to perform analysis on pavement health either by simply calculating horizontal and vertical strains under pavement layers or by crack detection models inside pavement structures by supplementing information from moisture, temperature and traffic related sensors. With optimum integration of such combination sensors, engineers can predict the optimum rehabilitation time of the pavements and reduce a huge amount of budget spent on infrastructure reconstruction.

“…In addition, the numerical simulation using sponge layer boundary condition is mostly used, and then it is not efficient for several actual cases like truncated domains. For this reason, the Generating Absorbing Boundary Conditions (GABCs) [41,42] is strongly recommended to investigate easily the wave-current-structure interaction where the wave and current are coplanar, and opposite.…”

The purpose of the work is revolved around presenting a literature review applied to wave-structure interactions. During this literature review, three types of breakwaters are presented: Bottom submerged breakwater, submerged plate, and seawalls breakwaters. Further, a numerical method used recently to study wave-structure interactions is presented. Furthermore, a simple analytical model is illustrated. Next, an experimental technique then also is depicted. For more details, this review will focus clearly on submerged bottom breakwater in discussion section for the reason of the importance of this breakwater for many hydrodynamic applications. Finally, valuable remarks will be deducted in the conclusion section.
