Power Vapor Stack – Vibration & Fatigue Assessment
Challenge: A vertical stack was experiencing dynamic stress and displacement due to wind-induced vortex shedding.
Our Approach: Intelico performed detailed structural and fatigue analysis to evaluate wind effects. We assessed the performance of Fabreeka damping material, which showed limited impact on static displacement but effectively reduced vibration amplitudes. The modeled fatigue behavior under various wind loads informed maintenance and retrofit strategies for enhanced reliability.
Structural Retrofit Design
Challenge: A thin-walled 70-foot steel stack showed signs of vibration, base cracking, and failed to meet minimum thickness standards above elevation 40’, posing risk under high wind loads.
Our Approach:Intelico performed structural analysis and FEA modeling per ASCE and ASTM standards. We designed a retrofit using longitudinal stiffeners and circumferential angles to reduce stress, improve stability, and meet design requirements under wind speeds up to 50 mph.
