Abstract:
This study investigates the effective stiffness of reinforced concrete (RC) low-rise walls with a shear span-length ratio between 0.5 and 1.5. Based on different mechanisms, the wall’s overall deformation is separated into four components: flexural, shear, bar-slip, and base sliding. Ten specimens, with exterior deformation measured using a densely arranged optional instrumentation system, were selected to study the key parameters that affect the effective stiffness of each deformation component. Accordingly, a model is proposed for each deformation component, and a database comprising test results from an additional 25 specimens is developed to validate the proposed models.
