“…Under the same section, the bearing capacity of the bolt specimen is superior to the welded specimen, but the energy dissipation capacity is roughly the same. Wan-Shin and Hyun-Do and Wan-Shin et al [22][23][24][25] studied the bearing capacity of the joint area between the coupling beam and the coupled wall through experiments. The results show that the coupling beam can be used as the first line of defense to enter the plastic stage first and ensure the post-failure of the joint area.…”

In this paper, a coupled concrete‐filled multicellular steel tube composite shear walls structure (CCSSW) is proposed. A finite element model (FEM) is developed to investigate the seismic behavior of CCSSW, and the model was validated by the tests. The effects of four parameters including axial compression ratio (ACR) on the hysteretic behavior of the CCSSW were studied. Then, a theoretical model for predicting the ultimate shear capacity (USC) of CCSSW was established. The results show that the failure mode of coupled walls exchanged from flexural failure to flexural‐shear failure with increasing the ACR, and it is recommended that the ACR should less than 0.6 to ensure the ductility requirement. To better realize the function of the first line of defense of steel coupling beam (SCB), following recommendations are concluded: the span‐to‐depth ratio range of SCB is 4.0–6.0, the wall stiffness ratio is 2.4–4.7, and low yield strength material should be used for SCB. The maximum error on USC between FEM results and theoretical results is 12.8%, and most of them are less than 10%, indicating the effectiveness of the proposed theoretical model.
