How to Use This Calculator

Enter sculpture weight (lbs) and height (in) for center-of-gravity estimation.
Select mount type (wall, pedestal, floor anchor, or ceiling) and surface type (concrete, wood, drywall).
Select seismic zone -- zones 3-4 require engineered anchors.
Review anchors needed, anchor size, design load (lbs), and actual safety factor.
For public art and high-traffic areas, consult a structural engineer for anchor design approval.

What each input means

Sculpture weight (lbs): Total weight of the sculpture.
Sculpture height (in): Height of the sculpture (affects base plate sizing).
Mount type: 0 = pedestal mount, 1 = wall mount, 2 = ceiling/suspended, 3 = outdoor ground mount.
Surface type: 0 = concrete, 1 = masonry/brick, 2 = wood stud, 3 = drywall, 4 = steel.
Seismic zone: 0 = none, 1 = moderate (zone 2), 2 = high (zone 3-4).

Anchors/bolts needed: Number of anchors or bolts required.
Anchor diameter (in): Recommended anchor bolt diameter in inches.
Design load (lbs): Total design load including safety factor and seismic.
Achieved safety factor: Actual safety factor with selected hardware. Should be >= 3.
Embed depth (in): Required anchor embed depth for concrete/masonry.
Base plate width (in): Recommended base plate dimension (pedestal/outdoor mounts).
Base plate thickness (in): Recommended base plate steel thickness.
Seismic load (lbs): Weight multiplied by seismic factor.
Anchor cost: Cost of anchors/bolts.
Total hardware cost: Total cost of all mounting hardware.
