As a new composite wall system, because of advanced structure, excellent polystyrene insulation board, insulation effect, light weight, the simple and flexible construction method and well adaptability, polystyrene insulation board thin coating of exterior wall thermal insulation technology is widely used in China. In practical applications, thermal bridges and the board surface cracks that caused by improper handling of deformation joints and detailed structure are the main problem of the technology. In this paper, many problems are analyzed such as the crack causes, the plates overlap and the node structure treatment, and also corresponding solutions are proposed.

This paper addresses the seismic behavior of coupling beams with headed reinforcing bars in coupled shear wall system. Test variable included the replacement ratios of headed reinforcing bars. The results show that Specimen HB 50 exhibits a better stable behavior in comparison with Specimens Specimen CON and Specimen HB 30. Test results showed that the amount of diagonal reinforcing bars in the coupling beam may be reduced when headed reinforcing bars are utilized.

A nonlinear 3D solid model of hybrid coupled wall system with steel boundary elements has been founded by using FEM software ABAQUS to study its hysteretic behavior under cyclic loading, which considering the geometric large deformation and materials nonlinearity. To verify the efficiency of the model, two specimens with various coupling ratios of 30% and 45% are analyzed, and the results of analysis are compared with test ones. As the bearing capacities of both agree well in different loading stages, so the FEM model has enough accuracy and could be used to study the seismic behavior of hybrid coupled wall system with steel boundary elements. In addition, the results show that this new system dissipates energy by shear deformation of steel beams along and plastic hinge deformation at the bottom of wall, so it has better seismic performance.

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.

This paper presents the performance of an emerging prefabricated composite system made from profiled steel sheeting and dry board. Six full-scale wall specimens were prepared and tested under axial load. The results of the experimental investigation showed that the performance of the composite walls is governed by the strength of profiled steel sheeting while the dry board performed as a wall sheathed. A partial interaction between the profiled steel sheeting and dry board was achieved by using self-drilling screws. The maximum axial load capacity is 1329kN for the double sheathed wall. The failure behavior of single and double sheathed composite wall exhibited similar pattern such as global buckling and cracking. The developed composite wall system was found the great potential in prefabricated and modular construction in Malaysia.
