The design of seismically resilient non-structural systems, including building services, is a specialist design process and requires specialist engineering knowledge.

 

Restraining engineering systems: The first step is to determine earthquake demand and calculate the restraint forces for all linear, floor-mounted and suspended components (NZS 4219:2009). The next step is to design a restraint system for each component that has sufficient capacity to resist seismic forces. A typical restraint system consists of one or more anchor points, braces or supports and connections to the building component. NZS 4219:2009 requires the design and installation of a restraint system for each component that has sufficient capacity to support and resist the forces determined in the earlier design steps. All components and associated supports and restraints should be attached to the supporting structure so that seismic forces are properly transferred to the structure.

 

For all buildings, TMCo’s seismic specialist team can engineer the relevant non-structural systems. We will undertake design, inspection and sign-off for each component. 

 

  • Anchors, fixings and fasteners
  • Braces and supports
  • Restraining piping systems
  • Restraining ducting
  • Restraining electrical services
  • Restraining tanks
  • Clearances between components
  • Flexibility
  • Restraining passive fire systems
  • 3D full coordination of services ability

 

To ensure we get the best solutions for the project (maximum performance with minimum cost, visually unobtrusive and readily constructable), we have spent many hours with suppliers and installers to determine the best products and bespoke designs. TMCo are now the go to for seismic design and sign-off for contractors, architects, project managers and even other engineers.
