Can custom metal ceilings be used in seismic zone constructions?
Custom metal ceilings are well suited for seismic zones when designed with appropriate hardware and detailing. Aluminum’s light weight reduces inertia forces during tremors. PRANCE uses flexible seismic clips and slip-joint hangers that allow controlled movement without panel damage.
Seismic suspension rails are engineered to accommodate lateral displacements. Rails are anchored with resilient connectors to the structure above, isolating the ceiling plane while maintaining plane integrity. Panels attach to rails via hook-on systems that permit slight shifts, preventing stress concentrations at joints.
Designers must follow local seismic codes (e.g., ASCE 7 or Eurocode 8) for allowable inter-story drift and ceiling deflection. PRANCE provides stamped engineering calculations and design drawings specifying hanger spacing, connector types, and rail profiles to meet requirements.
During installation, installers torque anchors and test hanger movement to confirm compliance. This comprehensive approach delivers custom aluminum ceilings that remain intact and safe during and after seismic events, protecting both occupants and architectural finishes.
