    Abstract:

    Cyclic tests were carried out on a conventionally reinforced concrete shear wall and three sandwich shear walls with concrete filled steel tubes (SW-CFT). The vertical compression forces on the experimental specimens were varied. The failure mode and hysteretic behavior of each experimental specimen under the combined vertical compression and lateral cyclic loading were evaluated. The equations to calculate the wall lateral resistances associated with the yielding states were derived. The experimental specimens were also simulated by the computer program-XTRACT. Comparisons revealed that the derived equations and the computer model both provide reasonable predictions for the wall resistances. The result show that the SW-CFTs exhibited high horizontal bearing capacity and energy consumption. In addition, the axial compression ratio is proportional to the strength exaltation and has only marginal effects on the seismic behavior of the SW-CFTs within the test range in this study.
