Slender Columns

This article provides data of axial load-bending moment capacities of plain and fiber-reinforced geopolymer concrete (GPC, FRGPC) columns. The columns were reinforced by double layers of longitudinal and transverse reinforcement using steel and/or glass-fiber-reinforced polymer (GFRP) bars. The concrete fiber-reinforcing materials included steel and synthetic fibers. The columns data included different parameters like the longitudinal reinforcement ratio, the applied load eccentricity, and the columns’ slenderness ratio. The data was collected from different analysis output files then sorted and tabulated in usable formatted tables. The data can support the development of design axial load-bending moment interactions. In addition, further processing of the data can yield analytical strength curves which are useful in determining the columns stability under different structural loading configurations. Researchers and educators can make use of these data for illustrations and prospective new research suggestions.

Glass fiber reinforced polymers (GFRP), with their advantage of corrosion resistance, have potential to be used as structural members in civil engineering constructions. Pultruded GFRP angle section trusses could be used instead of steel sections in remote areas and in areas prone to corrosion. The objective of this paper is to study the strength of GFRP angle sections under concentric axial load. Glass fiber reinforced polymer (GFRP) made of E-glass and Isophthalic polyester resin and manufactured by pultrusion process was used for the experimental study. Two GFRP angle sections of size 50 × 50 × 6 mm and 50 × 50 × 4 mm and lengths 500 mm, 750 mm, and 1000 mm were chosen for the study. Further, finite experimental element analysis of the GFRP angle sections was done using ANSYS software and validated with the experimental results. The validated FE model was used for parametric studies varying the slenderness ratio and flange width to thickness ratio (b/t) ratio. It was observed that length of the specimen and thickness influenced the buckling load and buckling mode. An increase in b/t ratio from 8.3 to 12.5 decreases the load carrying capacity by almost 60% at a slenderness ratio of 50.

Fiber reinforced composite materials are attractive because of their properties such as high toughness, water resistance and can be adapted to meet the specific needs of a variety of applications. Incorporation of natural fibers can reduce the dependency over synthetic fibers. In this work, Jute glass fiber reinforced composites are fabricated by simple hand lay-up technique using epoxy resin as a matrix and various mechanical properties like tensile strength, flexural strength, impact strength and also the water absorption properties of the composite specimens are evaluated and analysed thoroughly. It is observed that incorporation of optimum amount of jute fibre with glass fibre improved mechanical properties can be achieved. Finally cost of composites are analysed and compared.

Usage of Natural Fiber Composites (NFC) is increased rapidly due to the bio degradability nature of the fibers. These natural fibers are mixed with synthetic fibers to obtain better mechanical properties. In this study, pine apple and glass fiber reinforced epoxy composites are developed and their mechanical properties were evaluated. Composites were prepared by varying the fibers content and by using hand layup process with glass moulds of size 160 x 160 x 3 mm3 . The obtained laminates were sliced as per the ASTM criterion to test the properties. Higher glass fiber content in the composite specimen obtained higher mechanical properties. The composites can be utilized for the purpose of manufacturing components like doors panels, desks, roof tops etc.

Glass fiber reinforced plastics are widely used in civil engineering because of their advantages such as light weight, high strength, good pollution resistance, and corrosion resistance. This study investigated the buckling bearing capacity, failure characteristics, and slenderness ratios of GFRP solid bars with circular cross-sections subjected to axial compression. A total of 18 specimens were categorized into six groups. The slenderness ratios ranged from 57 to 123. It was found from experiments that the instability mode of the specimens was extreme point instability, and a bearing capacity platform phenomenon was observed when overall lateral instability occurred. The failure mode was axial and transverse tearing failure of the material in the middle of the specimen. During buckling, the tensile side was transformed from the compression of the resin matrix to tension in the fibers. The elastic modulus of glass fiber was much lower than that of the resin matrix. After tension occurred, increased deformation led to a rapid increase in lateral bending, which resulted in the phenomenon of the bearing platform. At ultimate deformation, brittle failure of the specimen occurred. The buckling load of the specimen decreased sharply with an increase in the slenderness ratio, and stress ratios decreased from 34.95% to 6.73%. It is suggested that the slenderness ratio not exceed 80. Finally, based on experimental results, a practical method for calculating the stable bearing capacity of solid GFRP poles is proposed.

The natural fiber-reinforced polymer composite is swiftly growing both in phrases of their industrial applications and fundamental research. They are renewable, cheap, absolutely or in part recyclable and biodegradable. The incorporation of herbal fibers consisting of sisal with glass fiber hybrid composites has additionally received growing industrial packages. Herbal and synthetic fibers are mixed in the same matrix (unsaturated polyester) to make sisal/glass fiber hybrid composites and the mechanical residences of those hybrid composites had been studied. A giant development in mechanical homes of sisal/glass fiber hybrid composites has been observed. the chalk powder (additive) is likewise introduced to the resin (unsaturated polyester) in proportions of 1%, 2%, 3% by way of weight of resin respectively and sisal/glass fiber hybrid composites were organized through the usage of this resin to take a look at the effect of chalk powder on mechanical homes of those hybrid composites. It is also found that because the chalk powder quantity increases tensile and flexural residences are decreases.
