GT STRUDL® - Base Plate Design 

 

Base Plate Wizard (BPW)
The Base Plate Wizard (BPW) is a graphics-based tool that helps you create models of base plates anchored to bearing surfaces with one or more attachments.

Base plate analysis models consist of:

  • Plate
  • Holes
  • Notches
  • Tabs
  • Attachments
  • Anchors
  • Stiffeners
  • Bearing surface data
  • Boundary conditions representing shear lugs
  • Edge welds
  • Other relevant data

Engineers may specify:

  • Plate Dimensions, notches, holes, and skewed edges
  • Finite element mesh size
  • Attachment location and rotation (up to 25 attachments per plate), including:
    • AISC wide flanges, tubes, pipes, channels, tees, and angles
    • User-defined shapes
    • Attachments may be rotated in-plane
    • Attachments may be modeled as an in-plane rigid solid or as a FE mesh extension
  • Anchor location and properties
  • Anchors (up to 1,000) may be modeled as linear or nonlinear springs, or as frame members, including tension-only members
  • Bearing surface properties
  • Bearing surface stiffness may be specified as Fc’, E, or F/L**3
  • Gaps between the plate and bearing surface
  • Stiffeners may be rectangular, trapezoidal, or triangular
  • Modeling constraints not set by the bearing surface or anchors and loadings
  • Constraints allow extra boundary conditions at specified node locations
  • Cutouts enable modeling of tabs, holes, notches, and skewed plates
  • Base plate models made be saved and recovered using .gtbp format
  • Results (anchor forces, bearing surface pressure, plate stresses, and displacements) may be reviewed in the BPW
