Structural Design Requirements

• Intermediate structural support is required to resist applied velocity and pressure loads for dampers that consist of two or more sections in both height and width.
• Tubular structural steel support may be required for large multi-sectioned dampers.
• A non-insulated Tamco damper weighs approximately 5 lbs/ft² (24.41 kg/m²). An insulated Tamco dampers weighs approximately 6 lbs/ft² (29.29 kg/m²).

MAXIMUM DEFLECTION:

• The structure providing intermediate support must be designed to resist the highest pressure load, with deflection of less than L/230. This applies whether the pressure load is created by the mechanical system, by wind load, or if the damper is mounted on the exterior of the building.
