Abstract:
This research presents modeling methodologies of squat shear walls with boundary elements to predict the shear strength. The proposed approaches are composed of an iterative analytical method and simplified design equations for design purposes. Upon validating the methodologies against existing experimental data, shear response of the squat walls subjected to lateral loading is examined to understand the behavior of the web and the compression and tension boundary elements. Model outcomes indicate that the shear strength contribution of the web and the boundary elements accounted for 58% and 42%, respectively, indicating that the contribution of the boundary elements should not be neglected. Contrary to the provision of current design specifications, both horizontal and vertical reinforcements contributed to the shear strength of the web. According to statistical evaluations, the proposed models outperform existing models in terms of capacity prediction. The effects of major parameters on shear capacity of squat walls are addressed from a practical standpoint.
