|Development, Maintenance, and Technical Support|
This project consists of the ongoing development, maintenance, and technical support for the BRASS™ Suite, which includes analysis/design programs and GUI applications for girders, piers, culverts, bearing pads, mast-arm and high-mast poles, splices, trusses, live load distribution, and routing/permiting. Many of these projects involved significant application and interpretation of the AASHTO Standard Specifications for Highway Bridges, the AASHTO LRFD Bridge Design Specifications, the AASHTO Manual for Bridge Evaluation, and the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaries and Traffic Signals.
|Development and Maintenance|
This project was to develop an incident tracking system for the BRASS™ Suite. This system allows users to submit questions, requests, and errors as well as attach any supporting files to help illustrate the concern. BridgeTech currently maintains this system.
Assessment and Evaluations of I-80 Truck Loads and their Load Effects
The research objective was to examine the safety of Wyoming bridges on the I-80 corridor considering the actual truck traffic on the interstate based upon weigh in motion (WIM) data and recommend changes to the design live load factor for Strength and Service limit states. BridgeTech was the prime contractor and co-principle investigator, teaming with Dr. Michael Barker and Modjeski & Masters, for this research.
Simplified Live-Load Distribution-Factor Equations
This project was to develop recommended LRFD live load distribution factor design equations for shear and moment. BridgeTech was the principal investigator for this research. See NCHRP Report 592.
|New Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals|
This project was to develop new specifications for structural supports for highway signs, luminaires, and traffic signals. BridgeTech was the principal investigator for this research. See NCHRP Report 796.
