The London Millennium bridge due to the crowd loading and synchronous lateral excitation caused on the opening day, the bridge was swaying too much in an
Apr 24, 2026
This swaying may lead to the crowd unintentionally falling into lockstep because it''s easier to go with the flow of the swinging bridge than fight it.

A big enough crowd can start a bridge swaying When we cross a bridge, we expect it to remain level, but a big enough group of pedestrians can

The Millennium Bridge, officially known as the London Millennium Footbridge, is a steel suspension bridge for pedestrians crossing the River Thames in London,
Jul 01, 2026
Human activities, such as walking, running, jumping, swaying, etc. could cause horizontal force which in turn could cause excessive dynamic vibration in the
Mar 04, 2026
Two researchers at Ohio State University have built a model to further explore the swaying experienced by the Millennium Bridge in London. In their paper published in the journal

1. Wind Forces Large gusts of wind can cause bridges to sway and twist. This occurs when wind applies uneven pressure on the bridge''s deck and supporting structures, creating

Side sway is defined as the horizontal displacement of a frame subjected to lateral loads, resulting in relative lateral displacement of the ends of some frame members and causing additional moments in
Jul 24, 2025
Properly identifying the type of frame helps engineers determine the appropriate analysis methods, design considerations, and material usage. This article explores the differences between
Jul 12, 2026
A frame is considered to be non-sway (braced) if it is sufficiently braced by lateral bracing elements like structural walls. On the other hand, frames that provide lateral resistance only through columns are
Jan 07, 2026
Cross-wind loads, also known as vortex shedding, can cause bridges to sway. The shaking of a bridge occurs when the damping is small and the vortex shedding frequency is close to the natural

What Makes Bridges Wobble? Your Awkward Walk A new study asks: How many people does it takes to set a pedestrian bridge a-swaying?
Jan 25, 2026
But many bridges are serving successfully with sway frames in every other panel, even lift bridges whose alignment is critical. Some designs even eliminate sway frames entirely.

By analyzing and solving vibration problems, we prevent a swaying bridge and other dangerous situations. Contact our experts for more information.

Bridges are humans way of bandaging holes in the earth that are too vast for our frail bodies to cross easily.

The slope-deflection method for sway frames will be illustrated using the example structure shown in Figure 9.20. This is a simple portal frame structure with pinned column bases.
