Description:

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.
