    Seismic performance of monolithic shear walls with disjointed steel bars in the northern Shaanxi by Jun Peng, Zhiqi Li, Hairen Wang, Xiangyu Li

    Published 2025-07-01
    “…Key parameters influencing failure modes were systematically investigated. The findings reveal that: Specimens transition from flexural-shear failure to shear-dominated failure as the shear-span ratio decreases; Increased shear-span ratio reduces load-bearing capacity while enhancing structural ductility; Wall thickness variations exhibit limited impact on performance, whereas openings reduce load capacity but improve ductility; Effective composite action between precast panels and cast-in-place boundary elements with intact vertical connections demonstrates superior seismic performance. …”
