BRASS-CULVERT : Version 2.7  August 2015

This program is current to the AASHTO Standard Specifications for Highway Bridges, 17th Edition,  2002, the AASHTO LRFD Bridge Design Specifications, 7th Edition, 2014, with 2015 Interim Revisions, and the AASHTO Manual for Bridge Evaluation, 2nd Edition, 2010, with 2011, 2013, 2014 and 2015 Interim Revisions. 


This can analyze and design one, two, three or four barrel reinforced concrete rigid or flexible box culverts with or without bottom slabs. End skews can also be defined. Wall and slab thicknesses may be specified or the program will set the thickness.

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.
