Pedestrian bridges are often designed to be lightweight and architecturally elegant, but those same characteristics can make them susceptible to vibration. When excessive motion affects user comfort, tuned mass dampers (TMDs) can provide an effective solution. A recent bridge project presented precisely this challenge. Analysis performed during the design phase identified the key dynamic characteristics […]
Read MoreTuned mass dampers in introduced a sizeable amount of damping into the gym floor, significantly reducing floor vibrations.
Read MoreDEICON was featured in the December 2025 issue of Gas Compression Magazine with a technical article focused on vibration control in industrial piping systems. The article addresses how operational forces such as flow turbulence, compressor‑induced excitation, and two‑phase flow can trigger resonance in piping, leading to fatigue, reliability issues, unplanned downtime, and potential safety concerns […]
Read MoreIn an indoor cycling studio where up to 40 riders pedal rhythmically at about 60 rpm, staff noticed excessive vibration—particularly near the reception desk, located at the mid‑span of one of the long‑span bays. Numerical modeling and on‑site measurements revealed that the floor’s first natural frequency of 4.3 Hz aligned closely with the harmonic forces […]

Read MoreIn a new 2,150‑capacity, state‑of‑the‑art music and event venue, engineers sought an effective solution to mitigate rhythmic, audience‑induced vibrations in a 3‑sided, 270‑degree wrap‑around balcony. Because dynamic loads from concertgoers can cause noticeable vibration—particularly near mid‑span and edge regions—this project required a damping approach that preserved both comfort and architectural openness. To meet this challenge, […]
Read MoreDEICON implemented an air‑isolation vibration control system to dramatically reduce transformer hum in a 3300 KVA transformer installed on the penthouse level of a 16‑story corporate office building. The transformer’s tonal noise—primarily caused by magnetostriction of the core laminates, producing strong vibrations at 120 Hz and its harmonics—was transmitting through the floor into executive office spaces below. […]
Read MoreDEICON recently mitigated pedestrian‑induced vibration issues in a monumental staircase at a healthcare educational facility by installing three tuned mass dampers (TMDs) calibrated to the staircase’s first bending mode. Before installation, DEICON performed vibration measurements to confirm the natural frequency and inherent damping. After tuning and commissioning the TMDs, damping in the target mode increased […]
Read MoreTo address potential vibrations in the balcony system of a new, state-of-the-art, mid-size 2,150 capacity entertainment (music and event) venue, DEICON incorporated six tuned mass dampers (TMDs) into the 3-sided, 270-degree, wrap-around balcony, with bird’s eye view of the stage. When audience in music venues and theaters move rhythmically to music or performances, the dynamic […]
