- Wind-Induced Vibrations and their Effects on Steel and Aluminum Light Poles
Here’s a breakdown of the effects of vibrations on light poles and tips on how to mitigate those effects First-Mode Vibrations First-mode vibrations are caused by sudden, high-velocity gusts of wind They typically impact the top of the pole and cause it to sway
- Wind Induced Vibration - Hapco Pole Products
Wind induced vibration can be caused by steady, relatively low-speed wind (10-30 mph), by topography and by the structure to which the pole is mounted or nearby structures Destructive vibration is not an indication of substandard material, workmanship or design of pole
- Wind-Induced Vibrations - United Lighting Standards
Wind-Induced Vibration and the Effects on Steel and Aluminum Light Poles provides detailed information about what Aeolian vibration is, how it can be identified, how wind-induced vibration can affect the performance and strength of light poles, and ways the effects of vibration can be mitigated both pro- and retroactively
- LSI Pole Vibration Application Guidelines - LSI Corp
customers avoid issues from wind induced pole vibration This guide explains what to look for and how to minimize the potential damaging effects of wind on lighting poles
- Wind Harmonics and Vibration | Pole Resources | Acuity Brands
Vibration can be caused by steady relatively low speed wind (10-30 mph), topography or the structure the pole is mounted to can also have impact Studies indicate that the natural turbulence of the air stream at higher wind velocities, above 30 mph, inhibit vibration
- Damping Wind-Induced Vibrations on Low-Level Lighting Poles - STRUCTURE mag
Wind-induced vibration is an ever-present issue in lighting support design It can cause seemingly magical movement of lighting poles, even when no storm or extreme wind event is present Engineers recognize this “pole dance” as resonance
- Wind-Induced Vibration and the Effects on Steel and . . . - Lyte Poles
Among the types of vibration that effect steel and aluminum light poles, wind-induced vibration is particularly detrimental Although light poles are designed to respond dynamically to the phenomenon, under the right conditions, wind vibration can drive even the most soundly designed structures to fail
- Light Pole Vibration Guidelines and Fixes - Access Fixtures
Light pole vibration refers to the oscillation or swaying of light poles, typically caused by wind This can occur in two main modes: first mode (harmonic vibration) which affects the top of the pole, and second mode (resonance vibration) which occurs near the pole’s midpoint
- Wind-Induced Vibration And The Effects On Light Pole
When gusts occur at extremely high wind speeds (50 to 70 mph), severe "whipping" and "pulsation" may occur, resulting in radical movements and high stresses at the pole base Second mode vibration is more disconcerting than first mode vibration
- CURRENT LIGHTING POLE VIBRATION APPLICATION GUIDE
Wind induced vibration can lead to reduced performance in the pole systems and may result in structural failure Environmental variables like wind conditions, terrain, landscape, and site structures greatly infl uence how wind will aff ect pole systems
