Seismic Behavior of Steel Reinforced High-Strength Concrete Composite Walls

Eight steel reinforced high-strength concrete composite walls were manufactured and quasi-statically tested. The testing objective was to investigate the seismic behavior of composite walls, including the failure mode, hysteresis curve, deformation, energy dissipation, and stiffness degradation. The results showed that all specimens failed during the flexural mode. The lateral load-resisting capability and deformation capability significantly increased with increasing steel ratio and stirrup characteristic value. In addition, formulations were proposed to evaluate the lateral load-resisting capability of steel reinforced concrete (SRC) composite walls, and the evaluated results exhibited good agreement with the test results.
