Some suggestions to ensure a smooth inspection process:
Get your codes officer to inspect and sign off your installation to the drawings
Make sure you wear your safety harness when required.
In general…when working with overhead suspended systems where people may be underneath;
Any overhead load must have connections rated for a minimum of 5x the rated load of the system and be slip critically connected.
In a seismic zone if your system is connected to the building it must pass the same structural requirements as the building itself.
Seismic bracing is required in all earthquake zones (you’d be surprised about the quantity and location of them). Make sure you check the applicable seismic maps to find your local acceleration requirements
No component of the system may be yielded, permanently deformed in any way by connections or loads applied to the system and must have the appropriate design safety factor
Yielding of truss chords or webbing by
Crushing by clamps,
Inappropriate spacing of supporting members.
Application of local moment forces applied to chord tubes by improperly coupled cantilevered under-slung loads from
Be exceedingly cautious about overloading the lower truss chord of a space frame style truss locally as it is the only thing keeping the truss in the air. A rupture in that member due to the combined stresses of tensile loading, twisting, and or crushing can mean instantaneous failure of the load bearing system and subsequent loss of control of the suspended load.
No wrapping of flexible supports in a way that can yield space frame truss webbing
DISCLAIMER: The above are some guidelines and warnings and in no way are to be construed as engineering advice, but merely to suggest that you familiarize yourself with the codes relevant to your project due to the serious nature of the safety requirements, and encourage you to seek the services of a professional structural engineer licensed in your area.
If you are working with a pre-engineered system certified for use in your locality:
Install it according to the installation drawings using all the correct hardware and connections.
Make sure you have the local building and codes enforcement officer inspect and sign off your installation.
If you are not working with a pre-engineered system certified for use in your locality.
Obtain the design services and stamps from a professional structural engineer licensed in your area to create your system.
Install according to the installation drawings using all the correct components, hardware and connections.
Make sure to have the local building and codes enforcement officer inspect and sign off your installation.
