BRASS-CULVERT™

BRASS-CULVERT™ – Version 3.2 – October 2017

The program is current with the AASHTO Standard Specifications for Highway Bridges, 17th Edition, 2002, the AASHTO LRFD Bridge Design Specifications, 8th Edition, 2017, and the AASHTO Manual for Bridge Evaluation, 3rd Edition, 2017.

BRASS-CULVERT™ is designed to assist the bridge engineer in the design, review, or rating of reinforced concrete, rigid or flexible, box culverts with up to ten cells. Culverts may be precast or cast-in-place with or without a bottom slab. Cells may be different sizes; however, the overall height of the culvert must be the same. The wall and slab thicknesses may be specified and/or sized by the program. Analyses and designs may accommodate either detailing with continuous or simply-supported slab-wall details.

AASHTO guidelines are followed and Service Load Design, Load Factor Design or Load and Resistance Factor Design may be specified. Member capacities are designed based on applied truck load, soil fill, self-weight and water pressure. Standard AASHTO and user defined truck loadings can be specified. Output generated by the program includes: culvert geometry; moments, shears, and axial forces at tenth points; stresses; required area of reinforcement; steel design table; splice lengths; weights and volumes of steel and concrete; and influence ordinates. Critical design moments, shears, and axial forces for each member are summarized. Flexural rating computations may be optionally computed.
