Geopolymer concrete‐filled cold formed steel composite beams can exhibit high durability and adequate strength. The geopolymer concrete is used to manufacture the cold‐formed steel tubular composite beam due to the significant advantages, such as greater in strength resisting capacity, higher‐energy dissipation capacity, and more stiffness than the regular one. This paper reports an experimental investigation on the behavior of rectangular geopolymer concrete‐filled cold‐formed steel composite beams. In order to investigate the mechanical behavior (such as flexural, shear, and torsion) of geopolymer concrete‐filled cold‐formed steel tubular composite beams (GCFTBs), 48 beam samples were tested. The 16‐GCFTBs and another 16‐GCFTBs were tested under flexural and overhanging, respectively, which the 16‐GCFTBs were tested under pure torsion. The relationships for load–displacement, torsional moment‐rotation angle, energy dissipation capacity, ductility, and failure mode were analyzed. The test results showed that the increase in cross‐sectional area and curing temperature had a significant effect on bending, shear and torsion behavior. Although the increase in the cross‐section ratio (height/width) increased the bending moment capacity, it decreased the displacement capacity and caused a decrease in ductility. Curing conditions and cross‐section ratio affected strength, displacement capacity, and experimental modulus of elasticity in both bending and shear tests. Increasing the cross‐section ratio and curing temperature resulted in an increase in ductility. Contrary to bending test and shear test, curing temperature, and cross‐section ratio increased both torsional moment strength and rotation angle in torsional moment tests.

“…The SCC is a special type of concrete that settles in the mold without the need for operator and vibration through its own weight. SCC was first applied in Japan in the 1980s, in order to reduce costs and improve the quality of the concrete industry [21,[28][29][30][31][32]. Although, the materials used in the mix are the same both SCC and conventional concrete, the mixing and the composition are different from each other.…”

Concrete generally consists of cement, water and aggregate. The cement constitutes about 30% of concrete by volume. Therefore, the varying cement composition plays a crucial role in the behavior of concrete. Since the reinforced concrete (RC) structures could be exposed to very different climatic conditions, as a result of geographic location and altitude, it is important to evaluate the performance of cement based composites [1][2][3]. Cement is widely used in concrete applications such as: bridges, dams, cohesionless soil grouting, cement-based mortar, drainage channels, and foundation planning and tunnels as well as RC structures. The binding ability of cement provided a compact system between coarse and fine aggregates in the concrete mix [4][5][6][7]. The cementbased materials (such as fly ash, silica fume, polymers, blast furnace slag, and etc.) have been used to improve the characteristic properties of cementing system. Besides, the water/binder and curing time significantly affect the rheological and mechanical properties of the composite [6][7][8][9][10][11]. Temperature variation causes major problems for cement, mortar, and concrete due to the accelerated hydration of conventional cements and the rapid evaporation of mixing water. High tem-

This study aims to experimentally investigate the torsional behavior of acrylic latex polymer and alkali‐resistant glass fiber‐reinforced composite shear walls and load‐bearing sandwich panels. Also, this study was aimed to experimentally examine the changes in the torsional moment capacities, twist angle values, energy dissipation capacities, ductility index, and rigidity of the samples for the presence of the additives added to concrete, size, presence of reinforcement in sandwich panels, and effect of sandwich panels. Within the scope of this work, a control sample, two composite shear walls, and two sandwich panels were produced (1500 × 1200 × 150 mm). While adding 5% acrylic latex to the concrete phase of one of the composite shear wall groups, in the other group, both 5% acrylic latex and 1% alkali‐resistant glass fibers were added to the concrete. While the core structure of the sandwich panel group is reinforced, the other group is produced without reinforcement. A total of 10 samples were loaded out of the plane and a torsional moment is created. As a result of the experiment, the torsional moment, twist angle, and energy dissipation capacities were increased for the samples with acrylic latex and alkali‐resistant glass fiber. While glass fibers increased the ductility index of the test samples, they decreased the stiffness value. Acrylic latex, on the other hand, does not have much effect on the ductility index and stiffness value and increased its energy dissipation capacity. Reinforced sandwich panel samples presented greater torsional moment capacities and stiffnesses compared to composite walls, and less ultimate twist angles and energy dissipation capacities. In addition, although the experimental results of the sandwich panels without reinforcement are lower than the other groups, these also showed load‐bearing capability under the effect of the torsional moment.
