“…Scholars have studied a variety of different types of shear walls, such as shear walls with shaped steel frame columns (Goel, 2004), rectangular and U-shaped concrete-filled steel tube composite shear walls with framed columns (Wang et al, 2023), corrugated steel plate composite shear walls (Luo et al, 2023), steel frame-steel plate composite shear walls (Lei et al, 2023), network-double steel plate concrete composite shear walls (Zhang et al, 2022), steel tube shear walls (Wu et al, 2018), etc. These openings are generally arranged regularly along the height, dividing the original shear wall into two or more slender walls connected by beams.…”

PurposeBased on the weak seismic performance and low ductility of coupled shear walls, engineered cementitious composites (ECC) is utilized to strengthen it to solve the deformation problem in tall buildings more effectively and study its mechanical properties more deeply.Design/methodology/approachThe properties of reinforced concrete coupled shear wall (RCCSW) and reinforced ECC coupled shear wall (RECSW) have been studied by numerical simulation, which is in good agreement with the experimental results. The reliability of the finite element model is verified. On this basis, a detailed parameter study is carried out, including the strength and reinforcement ratio of longitudinal rebar, the placement height of ECC in the wall limb and the position of ECC connecting beams. The study indexes include failure mode and the skeleton curve.FindingsThe results suggest that the bearing capacity of RECSW is significantly affected by the ratio of longitudinal rebar. When the ratio of longitudinal rebar increases from 0.47% to 3.35%, the bearing capacity of RECSW increases from 250 kN to 303 kN, an increase of 21%. The strength of longitudinal rebar has little influence on the bearing capacity of RECSW. When the strength of the longitudinal rebar increases, the bearing capacity of RECSW increases little. The failure mode of RECSW can be improved by lowering the casting height of the ECC beam in a certain range.Originality/valueIn this paper, ECC is used to strengthen the coupled shear wall, and the accuracy of the finite element model is verified from the failure mode and skeleton curve. On this basis, the casting height of the ECC casting wall limb, the strength and reinforcement ratio of longitudinal rebar and the position of the ECC beam are studied in detail.

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.

“…Secondly, the latest research results of scholars at home and abroad show that adding steel fiber into concrete can effectively improve the seismic performance of RC members, including the RHSC shear wall (Bekő et al, 2015;Peng et al, 2015;Li et al, 2016;Li et al, 2023c). The seismic behavior of steel fiber reinforced concrete (SFRC) shear walls subjected to reversed cyclic loading have been tested by several scholars (Zhou et al, 2018;Lou et al, 2021;Zadeh et al, 2021;Zhang et al, 2022). Just as anticipated, because the randomly distributed steel fibers can effectively improve anti-cracking property, tensile strength, shearing property, toughness, durability and seismic performance of matrix concrete, they can greatly improve the seismic performance of SFRCSW (SFRCSW), reduce the degree of reinforcement aggregation, and increase construction efficiency (Li et al, 2023d;Li et al, 2023e;Gu et al, 2023).…”

In the paper, an innovative shear wall, which is referred to as steel fiber reinforced concrete (SFRC) shear wall with concrete filled steel tube (CFST) columns, is introduced, based on the high bearing capacity and large stiffness of concrete filled steel tube column (CFSTC) and good cracking resistance and strong toughness of steel fiber reinforced concrete. The loading mechanism of steel fiber reinforced concrete shear wall (SFRCSW) with concrete filled steel tube columns is analyzed, and shear bearing capacity calculation method. A simplified model of the steel fiber reinforced concrete shear wall web softening tension bar is proposed, concrete and distributed web reinforcement to the shear bearing capacity of steel fiber reinforced concrete shear wall web is identified. Furthermore, a new algorithm to obtain the shear bearing capacity of steel fiber reinforced concrete shear wall with concrete filled steel tube columns is established, and then it is validated by using the test results of steel fiber reinforced concrete shear wall with concrete filled steel tube columns under low-cycle repeated loading. The results showed that all tested shear wall specimens exhibited obvious shear failure characteristics and a typical diagonal cracking pattern after test. The steel fibers obviously improved the crack forms of the steel fiber reinforced concrete shear wall web and the seismic behavior of steel fiber reinforced concrete shear wall with concrete filled steel tube columns. In addition, the proposed calculation method is scientific and accurate to analyze and predict the shear bearing capacity of low-rise steel fiber reinforced concrete shear wall with concrete filled steel tube columns.
