Limiting the Effects of Longitudinal Loads on Small Angle Lattice Transmission Towers
CenterPoint Energy Transmission Structural Design incorporates a "limiting" longitudinal unbalanced loading criterion into the design of tangent and small angle lattice transmission towers. This criterion ensures that a localized longitudinal failure in the arm occurs before tower body damage or failure; thereby, reducing overall structural damage and the probability of cascading failure from accidents during construction and operations. The success of the historical application of this criterion during both construction and operations and its application in the design, full-scale testing, and construction of a new 138 kV tangent tower will be presented. Full-scale testing is crucial to ensure that the parameters, loads, and capacities used during design produce results within an acceptable range. Unanticipated test results will be discussed in detail and correlation with a field construction failure provide an opportunity to prove the validity of the design requirement.
