Restoring Force Model for Composite-Shear Wall with Concealed Bracings in Steel-Tube Frame

Establishing a restoring force model is fundamental yet critical task for the analysis of structural responses to earthquakes. Such has substantial impact on results. Composite-shear walls with concealed bracings in steel-tube frames (composite-shear walls) offer several advantages, including convenient construction processes, high-bearing capacity, and excellent ductility. In this study, mechanical properties virtual test pieces were simulated when subjected low-cyclic-reversed loading ABAQUS. The simulation results agreed well experimental Subsequently, 24 additional obtained by adjusting parameters original four pieces, strength recycled concrete, thickness wallboard, axial compression ratio. Finally, was validated using from our previous study. demonstrate performance proposed simulating response composite shear wall. particular, can accurately reflect characteristics wall explored provides an effective theoretical support elastoplastic seismic similar types structures.
