The Calibration of the AASHTO ASD and LRFD for Maryland Sign and High Mast Lighting Structure Design

The Maryland Department of Transportation State Highway Administration (MDOT SHA) is working to update the standard design for sign and mast arm lighting structures. The following tasks were performed as a part of this research to assist with the update process: (1) Complete design parameters of MD-specified sign; (2) Defining wind pressure applicable by both allowable stress design (ASD) & load and resistance factor design (LRFD) design codes for the sign structure design for different regions of Maryland; (3) Determining the additional impact in transition to the LRFD design, including Maryland sign structure foundation designs; (4) Developing and calibrating fatigue load resisting connections; and (5) Reviewing the conformance of SABRE design models with alternate commercial licensed finite element analysis software.
