“…Otherwise, insufficient lateral details result in premature elastic buckling of the longitudinal bars and a sudden loss in load-carrying capacity [71]. Because of this, plain-concrete HCCs encased within outer and inner steel or FRP tubes are currently being used to increase the strength performance of HCCs and to overcome the brittle behavior related to the thin concrete wall [67]. These approaches, however, are difficult to implement and not cost-effective.…”

Hollow concrete columns (HCCs) reinforced with steel bars have been employed extensively for bridge piers, ground piles, and utility poles because they use fewer materials and offer higher structural efficiency compared to solid concrete columns with the same concrete area. Many experimental studies have been conducted to investigate the behavior of HCCs under different loading conditions and found that the structural performance of HCCs is critically affected by many design parameters. If not designed properly, HCCs exhibit brittle failure behavior, due to longitudinal bars buckling or the concrete wall failing in shear. In addition, the corrosion of steel bars has become an issue in reinforced-concrete structures. Therefore, this paper critically reviews the different design parameters that affect the performance of HCCs and identifies new opportunities for the safe design and effective use of this construction system. Moreover, the use of GFRP bars as reinforcement in hollow concrete columns is explored with the aim of developing a non-corroding and structurally reliable construction system.

“…FRPs also have the potential to strengthen the existing structural elements and reduce the amount of reinforcement and cementitious materials in concrete [39][40][41][42]. In recent years, some structural (i.e., walls, beams, columns, and slabs) and nonstructural (i.e., facades and curtain walls) elements in the buildings have been fabricated with FRPs [43][44][45]. Figure 2(b) shows some examples in which FRPs are used to construct facades of new buildings.…”

With the development of human society, the requirements for building materials are becoming higher. The development of polymer materials and their application in the field of architecture have greatly enhanced and broadened the functions of building materials. With the development of material science and technology, many functional materials have been developed. Polymer materials have many excellent properties compared with inorganic materials, and they can also be improved to enhance functional properties by blending or adding various additives (such as flame retardants, antistatic agents, and antioxidants). In this paper, polymer-based building materials are introduced with three classes according to the applications, that is, substrates, coatings, and binders, and their recent signs of progress in the preparations and applications are carefully demonstrated.

“…In a concrete-filled FRP tubular (CFFT) column, the axial bearing contribution of the outer FRP tube to the total load carried by the composite column would be very limited if the fibers are mainly oriented in the hoop direction. In fact, the compressive strength of an FRP tube in the orthogonal direction to the reinforcing fibers is mainly dependent on its resin matrix [45]. Therefore, the axial contribution of such FRP tube to a CFFT column is usually omitted during the calculation process.…”

Sawdust-reinforced ice-filled flax fiber-reinforced polymer (FRP) tubular (SIFFT) columns are newly proposed to be used as structural components in cold areas. A SIFFT column is composed of an external flax FRP tube filled with sawdust-reinforced ice. The compressive behavior of circular SIFFT short columns was systematically investigated. Four types of short columns with circular sections, including three plain ice specimens, three sawdust-reinforced ice specimens (a mixture of 14% sawdust and 86% ice in weight), nine plain ice-filled flax FRP tubular (PIFFT) specimens and nine SIFFT specimens, were tested to assess the concept of the innovative composite columns. The test variables were the thickness of flax FRP tubes and the type of ice cores. The test results indicated that the lateral dilation and the development of cracks of the ice cores were effectively suppressed by outer flax FRP tubes, thus causing a considerable enhancement in the compressive strength. Moreover, the compressive behavior, energy-absorption capacity, and anti-melting property of sawdust-reinforced ice cores were better than those of plain ice cores confined by flax FRP tubes with the same thicknesses. The proposed equations for estimating ultimate bearing capacities of PIFFT and SIFFT short columns were shown to provide reasonable and accurate predictions.
