Giampa, J. R., Bradshaw, A. S., Gerkus, H., Gilbert, R. B., Gavin, K. G & Sivakumar, V. (2019). The effect of shape on the pull-out capacity of shallow plate anchors in sand. Géotechnique 69, No. 4, 355–363, https://doi.org/10.1680/jgeot.17.P.269. The following mistakes have been identified. First, the incorrect source data was selected for plotting the ‘Present study’ data series in Fig. 5(a); the correct version of the figure is presented below.
Summary of experimental break-out factors for this study along with centrifuge tests from the literature for anchors with (a) circular and (b) square shapes

Second, equation (9) was missing an exponent; the correct equation is as follows.
Third, the plotted data points in Fig. 9 are incorrect due to a calculation error; the correct figure is presented below.
Ratio of predicted to measured break-out factors for the anchors with (a) circular, (b) square, (c) triangular and (d) kite shapes

Finally, the numerical values in Table 2 are incorrect due to a calculation error; the correct table is presented below.
The authors apologise to the readers of Géotechnique for these mistakes in the original paper.
