During service, transmission lines (TLs) will be subjected to unbalanced longitudinal loads
due to events such as conductor breakage, insulator failure, and sudden ice shedding …

Transmission lines (TL) are a very important part of our infrastructure. Their design is still
mainly based on a single extreme value wind speed, evaluated from synoptic or mixed wind …

The structural design of self-supporting transmission line towers (TLTs) typically employs
first-order elastic analysis to streamline practical engineering. Accordingly, due to their serial …

The simulation of progressive collapse of a power transmission tower-line system subjected
to extremely strong earthquakes is studied in this paper. A three-dimensional finite element …

Typical transmission line steel lattice towers are not designed for seismic excitations, based
on the assumption that their ultimate limit state is governed by climatic actions (wind and …

Progressive failures, or cascades, have played a major role in numerous transmission
system collapses around the globe during severe wind and ice storms. The failure of a line …

Ice loads exerted on the transmission line can increase the probability of conductor
breaking, which will lead to the stability failure of transmission towers. In this paper, a …

Conductor breakage with ice load is one of the major threats to the safe operation of
transmission lines. The ice load increases the unbalanced longitudinal tension, leading to …

To explore the effects and mechanisms of diaphragms on wind-resistant retrofitting of lattice
transmission towers, the authors developed finite element models of tower-line systems …

Because transmission tower-line systems are always exposed to the natural environment,
such structures are vulnerable to various meteorological conditions, and the rupture of a …
