It was an intense downward movement of air, known as downburst, or a super storm that left nearly 120 people dead.
Despite the fact that most weather-related failures of high-voltage transmission lines (HVTLs) are attributed to downbursts accompanied by heavy rainfall, research works are mainly focused on the behavior of the transmission towerline structures under dry downburst winds.
An official report released on Wednesday and filed by a State Council investigation team said that the Capsize was an extraordinarily serious disaster and was caused due to strong winds and heavy rains accompanied by a downburst that led to the capsize.

Buttrick said the weather service was not able to measure the severity of the winds in those towns, but it appeared to be from a downburst, a larger-scale microburst.
Section 2 reviews the analytical models of transmission lines, truss towers, and the coupled tower-line system, which contains the theoretical model, finite element (FE) model, and the equivalent model; Section 3 reviews the wind responses of the transmission tower-line system, which contains the structural performance subjected to various wind loadings, such as common winds, tornado, downburst, and typhoon, respectively, and the experiment and field testing on wind effects; Sections 4 and 5 discuss the seismic responses and ice-induced responses of the transmission tower-line system, respectively.

A bizarre wind - perhaps a storm-related phenomenon called a downburst - came out of nowhere Wednesday and briefly whipped through an interior courtyard garden at South Eugene High School, lifting a wooden bench into the air, bending a metal awning and sending students, a teacher and a Register-Guard reporter there on an unrelated assignment diving for cover.
