Improving methods for the determination of ice loads is important for raising the design efficiency of hydraulic structures. A disagreement between the SP 38.13330.2012 procedure for the evaluation of design ice load and full-scale data is demonstrated. A new formula for determining ice load based on comparison of different theoretical approaches and field data is presented. The effect of the planform of the structure on the ice load is analyzed numerically. The results show that the shape factors of the support can differ from those used in SP 38.13330.2012s.
