Area of Science:

• Structural Engineering
• Earthquake Engineering
• Materials Science

Background:

• Traditional shear walls are crucial for seismic resistance.
• Superposed shear walls offer advantages in construction and seismic performance.
• The role of concealed columns in these systems requires further investigation.

Purpose of the Study:

• To investigate the seismic performance and connection behavior of this new system.
• To evaluate the impact of eliminating concealed columns on structural integrity.

Main Methods:

• Nonlinear finite element analysis using ABAQUS software.
• Experimental research combined with computational modeling.
• Analysis of vertical seam connection performance under seismic loads.

Main Results:

• No significant difference in hysteretic performance or bearing capacity when concealed columns are omitted.
• Single-faced composite shear walls with different splicing forms exhibited bending-shear failure.
• The system without concealed column design maintained good overall performance and seismic behavior.

Conclusions:

• The proposed single-faced superposed shear wall system demonstrates robust seismic performance.
• Eliminating concealed columns is a viable design option without compromising structural integrity.
• This finding offers potential for simplified construction and improved efficiency in seismic-resistant structures.
