This research investigated the behaviour of a new form of composite shear wall system consisting of two skins of profiled steel sheeting and an infill of concrete under in-plane monotonic, cyclic and impact loading. The extensive experimental, analytical and numerical investigations of composite shear walls provided information on strength, stiffness, load-deformation response, steel sheet-concrete interaction, stress-strain characteristics and failure modes.Eight composite wall specimens with overall dimensions of 1626 mm (height) x 720 mm (width) were tested under monotonic, cyclic and impact loading. Steel sheet-concrete connections were provided by intermediate fasteners to generate composite action. Two types of steel sheets classified based on strength as mild and high strength and also, two types of concrete-infill namely Self-Consolidating Concrete (SCC) and Engineered Cementitious Composites (ECC) were used to construct the walls. An analytical model for shear resistance of the composite wall was developed based on existing models taking into account the shear capacity of the steel sheets, concrete core and steel-concrete interaction. Moreover, two non-linear finite element models for the composite wall under monotonic/cyclic and impact loading were developed using proprietary ABAQUS/CAE software. The performance of developed numerical models was validated against experimental results and then the models were utilized to carry out an extensive parametric study to understand the influence of material and steel-concrete interaction on the structural behaviour of the walls.

Composite Shear

The bundled lipped channel-concrete composite wall is an innovative structural wall. This wall has a series of advantages, such as convenient construction and high bearing capacity. Seven full-scaled specimens were tested and subjected to cyclic lateral loads. ABAQUS, which is a finite-element software, was used to simulate the test process. Hysteretic curves and skeleton curves were obtained. This process proved that the simulation effect of finite element was good. A parametric analysis was conducted on this composite shear wall to determine the effect of the wall under different parameters, such as the axial load ratio, the shear span ratio, and the intensity of steel and concrete. The formula for the bending capacity of normal section was deduced. The failure mode and factors that affect the shear capacity of the composite shear wall at a low shear span ratio were analyzed to obtain the composition of the shear capacity. Based on the superposition theory and statistical regression, the formula for the shear capacity of the inclined section was obtained.

Based on the research of composite walls at home and abroad, a construction method of continuous opening of the insulation layer in the specimen is proposed. In the edge component of the composite wall, the insulation layer should be thinned appropriately, the concrete on both sides should be thickened correspondingly, and U-shaped reinforcement should be used instead of stirrup. To study its axial compression test performance, five 1/2 scale composite shear wall specimens are tested under axial compression, including three composite wall specimens and two solid wall contrast specimens. The failure mode, load-bearing performance, deformation performance, and the collaborative work performance of wall are analyzed. The results show that the failure characteristics of the composite shear wall are similar to those of the solid wall, with splitting cracks at the corners and inverted triangular conical splitting at the top of the wall along the wall height direction, with no obvious bulging in the middle of the wall. The tie action of the ribs makes the concrete walls on both sides of the composite shear wall have good integrity and cooperative performance; the installation of the thermal insulation layer increases the overall thickness of the wall, improves the stability of the composite wall, and makes the composite wall axially compressed. The bearing capacity is not significantly reduced compared to the solid walls. Finally, according to the test results, the calculation formula of axial compression bearing capacity of composite shear wall is given, which provides the basis for the formulation of the code and engineering application.
