Abstract
High mast lighting poles (HMLP) are tallest lighting poles that are used in highway and intersections. This lighting pole helps to cover major area unlike smallest lighting poles. These poles vary in height from 30 to 76m. HMLP’s are supported at the bottom that is connected to concrete foundation with the help of large size anchor rods. In this study investigation is carried on about the post yield and anchor nut loosening. Due to the rotation of nuts after the post yield that leads to plastic deformation due to some external load factors like wind load. This problem can be analyzed by simulating non-linear post yield behavior using complex model. Finite-element (FE) modeling satisfies these requirements in the most accurate way possible. Octagonal, hexagonal and circular steel poles are the three different models considered for the analysis. Among these three models choose the model with highest stress and also adopting methods to reduce the stress at the anchoring due to the nut loosening.
Keywords- Base Plate, Bolt, Circular Pole, Gusset Plate, Hexagonal Pole, Pretension, Octagonal pole
