Abstract Anchors are a common type of foundations used to transmit forces from super structures to the soil. According to the direction of the tensile force, anchors may be horizontal, inclined or vertical. Anchors can be classified into three categories: 1) Gravity Anchors, 2) Plate Anchors, and 3) Piles. The present study is restricted to shallow horizontal anchor plates subjected to vertical pullout forces. In this research, laboratory test program was prepared to perform the experimental parametric study. Different parameters, such as embedment depth, anchor shape, tapering angle, kaolinite content, and water content, were studied to investigate their effects on the ultimate uplift resistance of such anchors. A theoretical study is also performed to check the validity of different available theoretical methods for predicting the ultimate uplift resistance of shallow anchor plates, and to check which of them is the closest to the experimental results. Finally, a modification is made for one of the theoretical methods to be valid to predict the ultimate resistance precisely. |
