The program is current with the AASHTO Standard Specifications for Highway Bridges, 17th Edition, 2002, and the AASHTO LRFD Bridge Design Specifications, 8th Edition, 2017.

BRASS-PAD™ designs and analyzes rectangular elastomeric bridge bearing pads with or without shims, using the Load Factor Design or Load and Resistance Factor Design specifications: Method A or B.

Program capabilities include:

  • Bearing analysis and iterative design capability.
  • User can specify whether to iterate on pad length or thickness.
  • Recommendations when bearing fails design check(s).
  • Analysis with or without keeper plates.
  • Analysis with or without shims.
  • Calculation of layer thickness to achieve rounded pad thickness.
  • AASHTO stress strain curves for durometer 50 or 60 hardness built in.
  • Analysis with or without anchor bolts.
