“…The use of pervious and perforated concrete seawall structures can mitigate the wave load on the structure and reduce wave reflection in front of the structure [156][157][158][159][160][161]. Such structures will also result in improved water quality and have lesser negative effects on coastal ecosystems due to exchange of flow between open sea and the enclosed regions [8,[162][163][164][165].…”

Increasing frequency of extreme weather events, driven by climate change, has resulted in an increasing demand for coastal structures to protect and stabilize shorelines. Concrete seawalls are a common category of coastal protection structures, designed with the primary objectives of absorbing wave action, preventing coastline erosion, and alleviating flooding. Much research has been carried out on improving the seawall performance. This work is a review of the current state-of-the-art in concrete seawalls focusing on design aspects including wave loading and innovative seawall designs, ecological considerations, and durability aspects. Wave loads on seawalls have received significant attention; however, their quantification remains a challenging task especially for novel designs. Drawing inspiration from natural shorelines, modification of surface complexity at a multitude of scales can improve the otherwise poor ecological performance of seawalls. The corrosion of the steel is a major durability concern, and the use of non-corrosive reinforcement can increase seawall durability towards corrosion. Examples of innovative seawall designs and systems which have the capability to outperform conventional seawalls are discussed. Advances in structural design, ecological engineering, and infrastructure materials science will drive the development of multi-functional seawalls which are sustainable, durable, and resilient.

“…Due to their advantages such as more flexible in meshing complicated structures, minimizing the number of elements for a given mesh resolution and reducing mesh-distortion sensitivity compared to the standard FEM, the arbitrary polyhedral finite element (pFEM) has attracted huge attention as well as applications in different fields of engineering, e.g. topology optimization, 1 plate structures, [2][3][4] solid mechanics problems, [5][6][7] fluid flow problems, 8 microstructures, [9][10][11][12] and so forth. The development of pFEM in recent years was clearly reviewed in Reference 13.…”

In this paper, we investigate the use of a consecutive-interpolation for polyhedral finite element method (CIPFEM) in the analysis of three-dimensional solid mechanics problems. A displacement-based Galerkin weak form is used, in which the nodal degrees of freedom (DOF) and their derivatives are both considered for the approximation scheme. Based on arbitrary star-convex polyhedral elements using piecewise linear shape function, the present method can have the advantage of being applicable to complicated structures. Nevertheless, the proposed interpolation technique gives higher-order continuity, greater accuracy with the same number of DOFs. The reliability and efficiency of the CIPFEM are proved by comparing the present results with those obtained by the consecutive-interpolation for tetrahedral element (CT4), conventional linear FEM using polyhedral elements (PFEM), and tetrahedral elements (T4) through numerical examples. Cantilever beam, concrete corbel, and complex hollow concrete revetment block are considered to show the excellent performance of the present approach.
