Paper Title:
Influence of Ice Covering on Stiffness of Tower Components
  Abstract

In the icing electric transmission tower computation, has neglected the influence of ice stiffness and geometric effect to the iron tower component's stiffness. In the heavy ice area, such simplification is possibly inappropriate. Base on the parallel principle, proposed the ice-coated compression bar flexural stiffness formula, and proofed result correctness through finite element computation. Took the circular solid section and circular tuber section ice-coated tower components for example, ice-coated tower components were equivalent to compound materials in heavy ice area. Under certain load condition, compared the deflection and stiffness of tower component covered the different thickness ice, which took the line load with equivalent to the compound materials. Result showed that in the heavy ice area, the ice geometry effect has increased the tower component stiffness. The influence is more obvious to the tower stiffness than its dead-weight.
