CulvertCalc 3.1 Installation Files (3.9 MB) 03/18/21
These files consist of RC-Pier example input files and documentation on the use of RC-Pier for a typical LRFD T-Pier design..
RC Pier Column
RC Pier Footing
These spreadsheets allow the user to determine top of slab elevations (CCS, CWPG, PPCB), beam line haunch elevations (CWPG, PPCB) and haunches (PPCB) for straight, constant width bridges.
The PPCB fabricator data spreadsheet is a form to collect prestressed beam camber data from fabricators.
The bridge deck drain spreadsheet may be used to assist the designer in locating deck drains. The Bridge Design Manual shall be consulted for deck drain policy requirements.
This spreadsheet was developed to aid the design of typical strip seal expansion joints. The Bridge Design Manual shall be consulted for the most up-to-date policies.
This spreadsheet was developed to provide LRFD Live Load Distribution Factors for Beam-Slab Bridges.
This appication assists with design of traditional concrete decks on prestressed or steel beams (Aashto Lrfd 2.5.2.4, 3.6.1.3.3, 4.6.2.1, 9, A13.4).
Some of these spreadsheets allow the user to determine typical pier loads based on the AASHTO LRFD code for use with the RC-Pier software. Some spreadsheets may be used in the LRFD design of typical pier caps, pile footings, and steel laminated elastomeric bearings.
This spreadsheet determines tension rebar development and splice lengths based on the 7th and 8th edition of the AASHTO LRFD code.
Instructions for iPD project cost estimating software.
The prepare cost estimate spreadsheet may be used to assist
the designer in estimating the cost of a project based on bid items.
