摘要：
Axial compression tests of 18 shear wall specimens were conducted to study the influence of stirrup ratio of concrete between tubes of shear wall on axial bearing capacity and deformation capacity. Mechanical behavior such as failure pattern, force mechanism, bearing capacity and deformation capacity was investigated. Experimental results show that with stirrup ratio increases, the ultimate compressive strain of concrete between tubes and the confinement effect of tubes on concrete inside increase correspondingly, and the bearing capacity and deformation capacity improve. Using the finite element program ABAQUS to analyze the axial compression performance of the shear wall with steel tube-confined high-strength concrete, and the results are in agreement with the experimental results. Axial bearing capacity formula for the shear wall is proposed according to the test and FEA results, which is in good agreement with experimental results. © 2016, Editorial Office of Journal of Building Structures.
