Abstract: The paradigm shifts in the history of predicting the wind related effects was shifted from early theoretical,numerical, experimental techniques, to Computer techniques in fully understanding the vibrational characteristics of a system like Bridge. Therefore, the structural dynamic analysis includes determination of the natural mode shapes and frequencies of an elastic structure in free unforced vibration. In this research paper, the software like ANSYS and others whose built based on Finite Element Method are adapted and well suited for this type of analysis since the mode shapes can be accurately derived from the geometrically complex of the structures, such as beams, and pylons sections that commonly found in slender structure like bridge. The FE structural model is typically formulated in SOLID-Works software as an Eigensystem,where the eigenvalues and eigenvectors represent the natural frequencies and the mode shapes, respectively. The lowest eigenvalues (1.1006e-008 Hz) correspond

Abstract: Recently, coastal environmental pollution is getting serious. Among these, beach erosion has great a significant impact. These coastal structures are made to minimize the loss of sand beach. For this reason, submerged breakwater has been indiscriminately constructed that is planned throughout south korea. In order to prevent erosion,some advanced countries have been installed submerged breakwater or breakwater. Despite of its purpose to keep the shoreline of the beach,it has a quite a few problems. In addition, the purpose of utilizing the space of the marine leisure users does not like that because of the disconnection of the sea using sea space. These methods have resulted in afurther erosion of the beach. Therefore, in this study, we propose to develop a economical method of artificial coral cell model that can mitigate degree rate of beach erosion and improve coastal environments without installing the submerged breakwater or breakwater for the maintenance. We compared and analyzed
