Premature failure of transmission towers due to extreme weather conditions and inadequate design methods have severe socio-economic implications. This study presents a state-of-the-art review of the research work related to failure of self-supported lattice steel transmission towers. Selected articles from literature were divided into broad categories namely—failure analysis techniques, joint slippage effects, retrofitting and investigations of failure due to earthquakes and high intensity winds. The former three aspects mentioned above are chosen for review in this paper since the latter two are very broad aspects by themselves. A systematic literature review has been conducted based 76 research articles after filtering from reputed journals. Advanced analysis involving computational models based on nonlinear formulations and modern finite element software and their potential to reduce the need for full-scale prototype testing have been highlighted. A description of the studies available on retrofitting techniques for transmission towers for intervention against impending tower failures—diaphragm and leg member retrofitting techniques and studies on retrofitting connections are also discussed. Key conclusions from the study that highlight the most useful findings from the various studies, limitations of the current study and directions for future research have been established.

由于极端天气条件和设计方法不当而导致输电塔过早失效，会产生严重的社会经济影响。本研究对与自承式格构钢输电塔故障相关的研究工作进行了最新的回顾。从文献中选出的文章分为几大类，即失效分析技术、接头滑移效应、地震和强风引起的失效的改造和调查。本文选择前三个方面进行回顾，因为后两个方面本身就非常广泛。从知名期刊筛选后的 76 篇研究文章进行了系统的文献综述。强调了涉及基于非线性公式和现代有限元软件的计算模型的高级分析及其减少全尺寸原型测试需求的潜力。还讨论了可用于干预即将发生的塔故障的输电塔改造技术的研究——隔膜和腿构件改造技术以及改造连接的研究。该研究的主要结论强调了各种研究中最有用的发现、当前研究的局限性以及未来研究的方向。
