“…An alternative design of a seawall system using BFRP bars was tested and the results of the seawall slab specimens demonstrated that the system design achieved the required performance [154]. Overall, there is a growing awareness of the properties of FRP as a structural material within the construction industry and there is ongoing research to further investigate where and how it can be used in concrete structures in pursuit of improved durability, performance, and resilience [155].…”

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.

“…Por lo tanto, en la búsqueda de nuevas alternativas la utilización de materiales compuestos reforzados con fibras resulta ser un buen candidato, ya que tienen una alta resistencia a la corrosión y altas propiedades mecánicas [31]. Por ejemplo, en los últimos 20 años se han construido puentes alrededor del mundo a través de materiales compuestos reforzados con fibras, ya sea que estos materiales fueron utilizados para la construcción parcial o total de todos los elementos que conforman a los puentes [32][33][34][35][36].…”

En este trabajo se presenta resultados sobre la evaluación de la resistencia/peso en una viga tipo I de material compuesto híbrido con fibras de algodón/vidrio (64% fibras de algodón y 36% fibras de vidrio). Se realizaron simulaciones numéricas a flexión a través del programa ANSYS y una prueba experimental a flexión en la máquina de ensayos Shimadzu AG-Xplus 100kN. Los resultados mostraron que es posible obtener una geometría optimizada dentro de la viga a través de la remoción estratégica de zonas de material sin comprometer la integridad estructural. Además, la prueba experimental a flexión en la viga de material compuesto mostró un valor superior en la relación de resistencia/peso (44) en comparación con la viga optimizada de aluminio 6061-T6 (39.65); este comportamiento se atribuye a que los materiales compuestos reforzados con fibras son generalmente menos densos en comparación con los metales, y a la distribución de las fibras de algodón y vidrio dentro de la viga.

The availability of fiber‐reinforced polymers (FRP) as an alternative for conventional steel reinforcement in concrete construction is increasing. To widen the scope of application, for example, in the case of prestressing, and to improve the bond behavior at the bar ends, end anchorages need to be considered. Within this paper, a new short‐length anchor representing a combination between a bond and mechanical anchor is presented using a special inner geometry to increase the load‐bearing capacity due to the mechanical wedge effect, with a bonding length of only 50 mm. Besides giving a short overview of different anchorage systems, the paper focuses on experimental investigations that were performed with mechanical bond anchors with a variation of the inner geometry of the steel anchorage, different FRP bars, and different load transfer media. A numerical investigation completes the study by showing an approach to calculate the presented mechanical bond anchors. It was found that a small thickness of the bonding material is favorable, and a decrease of the bonding length is not necessarily disadvantageous. A tensile failure of the FRP bars was not achieved, although a full exploitation seems promising since a utilization of up to 83% of a basalt FRP bar was reached.
