In the design and application process of shear wall with double steel plates and filled concrete,there is no universal approach,code and specification for this new type structure.In order to study the axial mechanical behavior of this new type structure,axial compressive tests on four wall specimens were conducted.The mechanical behavior and failure modes were analyzed under axial compressive loads,and the influence of the distance to thickness ratio and the number of pull bolt on the local bucking of steel plates,failure modes and bearing capacity were investigated.The results indicated that the distance to thickness ratio has significant effect on initial buckling of steel plate and failure modes of shear wall but little effect on the stiffness and bearing capacity of walls.
