Abstract
Based on the properties of lightweight aggregate concrete, the yield curvature and the ultimate curvature are calculated by numerical method, and the relationship between curvature ductility ratio and displacement ductility ratios is established for lightweight aggregate concrete shear wall. It is shown that the calculating results agree well with experimental results. The major influencing factors for ductility of lightweight aggregate concrete shear wall include with or without constrain edge conponent, the characteristic value of stirrup of constrain edge conponent, the axial compression ratio and the height-width ratio and so on.
