Effect of axial compression ratio on shear strength of reinforced light-weight concrete shear walls

For practical reasons, the axial compression ratio has always been a vital element in light-weight concrete shear wall design relating to its own shear strength and ductility. In this paper, based on the experiment, the shear strength and failure mode of mid-rise light-weight concrete shear walls under cyclic loads, especially under different axial loads, are closely examined. By using a softened truss model, analysis if made and satisfactory agreement between the theoretical results and experimental data is achieved so as to present an approach of design for the designers.
