Assessment of Structural Behavior of Transmission Line Tower using Strain Gauging Method
Veerendra Kumar Shukla,M. Selvaraj 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.4
Design of latticed steel transmission towers is a challenging task which involves lengthy modeling and detailing of significant amount of steel members and connections. After that full scale testing of towers validates the modeling and detailing and ensures that the towers are designed to withstand design loads without premature failures. In present work, a 132 kilovolt double circuit suspension tower has been considered for study. The tower was designed using Staad.pro software and the member forces were calculated at design loads. After design, the full scale testing of the tower was carried out. During testing, the strains in some of the critical members were measured using strain gauges. Using these strain values, the actual load in selected members are calculated. The paper provides the comparison between actual load in members during full scale testing and computed loads from software. The paper also discusses the possible reasons behind the difference between actual and computed loads. Loads on the tower at different points for different conditions are presented. The paper also provides a discussion about the possible reasons of premature failure of tower during full scale testing or at site and the remedial measures are presented to avoid the failure.

Failure Analysis of a Cruciform-Leg Transmission Line Tower
Veerendra Kumar Shukla,Munusamy Selvaraj,Kalla Vijaya Kumar 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.2
Design of latticed steel power transmission towers is a challenging task, which involves lengthy modeling and detailing of signifi cant amount of steel members and connections. The tower is analyzed and designed as a space truss and various members of tower are checked for Tension, Compression and Slenderness Ratio. Sometimes, due to unavailability of required sections or economical point of view, single angle sections are replaced by Cruciform Sections (made of two angles connected toe to toe). The cruciform section, when connected with single angle sections, generate bending moments due to eccentric loading at connection on application of loads on tower, which subsequently results failure of the tower. In the present work, a full-scale testing of a 400 kV tower with built-up leg (Cruciform Leg connected with Single-Angle Leg) has been conducted and the behavior of joint on application of loads has been studied. While testing, one of the legs buckled at the connection. The failure pattern of the leg has been validated using FEM analysis, and the reason of failure has been discussed. In order to confi rm the quality of steel, mechanical testing of steel used in leg has been carried out using UTM and results have been explained in the papers. The paper also gives some suggestions for the connection of this type of built-up sections used in tower in order to avoid such failures.
