## 1 Introduction  
The composite shear wall with steel plate and concrete refers to a new type of shear wall structure, which is mainly used in super high-rise buildings, and missile-and blast-resistant walls. The composite shear wall has a broad prospect of application due to its high bearing capacities and the reduction in its thickness, especially at the strengthened bottom of the core tube in super high-rise buildings, which have a higher requirement for the cooperative performance between the steel plate and concrete. However, the local instability of steel plate may lead to poor cooperative performance, which has a great influence on the axial compression performance of composite walls. Some related research on the axial compressive performance of composite walls has been carried out in recent years. The axial compressive performance of composite walling, comprising two skins of profiled steel sheeting with an infill of concrete, was analyzed by [PERSON] [1,2]. [PERSON] found a poor cooperativeperformance and a reduced axial compression capacity, due to the lack of a connection between the steel plate and concrete. Moreover, he reported that the axial compressive bearing capacity was affected by the local buckling of the steel plate and the eccentric cross-section of concrete, when different constructional measures between the steel plate and concrete were used to strengthen the cooperative performance. [PERSON] [3] considered the buckling effect of steel plate on the axial compressive bearing capacity of a lightweight steel-foamed concrete-steel composite walling system, and presented a calculation formula for the axial compressive bearing capacity, using the concept of a steel plate buckling coefficient and an effective width, proposed by [PERSON] [4; 5]. The double-skin steel concrete composite shear wall with a \"J\" interlocking hook, was put forward by [PERSON] [6]. Axial compression tests using 15 specimens were carried out and the calculation formula for the axial compression bearing capacity was put forward, considering the buckling influence of the steel plate. [PERSON] [7] carried out axial compression experiments using asteel-tubehigh-strength concrete shear wall, for which a bearing capacity calculation formula was established. The axial compression tests on the local stability of a composite wall with two skins of steel plate, were studied by [PERSON] [8], for which the theoretical formula for the elastic buckling of steel plate was derived. The constitutive model of the core concrete in the steel plate concrete composite shear wall with constraint bars, was theoretically analyzed by [PERSON] [9].  
However, previous research has paid little attention to the arrangement of steel plate within composite walling systems, which has a great influence on the cooperative performance between the steel plate and concrete. Therefore, axial compression experiments with different layout forms of steel plate were carried out in the subsequent study. This paper proposed a calculation equation for the axial compressive bearing capacity, considering local buckling of steel plate and the increase in the axial compressive strength of confined concrete. The calculated results were in good agreement with the test results.
