Column base
Fixed column base
Thick base plate, 4 corner anchor bolts and stiffener gussets: the base transfers a bending moment to the foundation. The column then contributes to horizontal stability (cantilever mast, portal). Trade-off: a significantly larger foundation block.
Components
- •Thick base plate (20-40 mm)
- •4-8 corner anchor bolts
- •Vertical stiffener gussets
- •Foundation sized for overturning
- •Non-shrink grout
When to use it
Moment frames, cantilevered canopies, masts, crane buildings, structures where bracing is impossible.
Common mistakes to avoid
- ✗Undersized foundation → overturning
- ✗Ignoring bolt tension (pull-out)
- ✗Plate without gussets → excessive plate bending
