ANALYSIS AND BIOGRAPHY SUMMARY CONSTRUCTION

(VDOTs) first ASTM A709 Grade 50CR (50CR) (formerly referenced as ASTM A1010) stainless steel bridge in Waynesboro, Virginia. In order to realize a truly low-maintenance structure, VDOT elected to use Grade 50CR steel for the bridge girders and cross frames, and to use stainless steel bolts for the bolted connections. ARKANSAS DEPARTMENT OF TRANSPORTATION ASTM A709, Grade 50W, or as specified. Subsection 817.02(b), Steel Items, is hereby deleted and the following is substituted therefor:(b) Steel Items. Bars, plates, and structural shapes shall be of steel conforming to the requirements of ASTM A709, Grade 36 (250), except that Charpy V-Notch Impact tests are not required.

Table 23. Linear regression coefficients for average thickness loss per each surface for Study A1 A709 GR50 specimens - "Corrosion Behavior of ASTM A1010 Stainless Steel Maintenance-Free Corrosion-Resistant Steel Plate For The ASTM A709 Grade 50CR steel showed good tensile and slip-critical bolted fatigue behavior that met the requirements of ASTM A709 Grade 50 steel. The study also showed that it can be successfully fabricated into a steel plate girder and has had good corrosion resistance in bridge applications. Maintenance-Free Corrosion-Resistant Steel Plate For BridgesThe ASTM A709 Grade 50CR steel showed good tensile and slip-critical bolted fatigue behavior that met the requirements of ASTM A709 Grade 50 steel. The study also showed that it can be successfully fabricated into a steel plate girder and has had good corrosion resistance in bridge applications.

Slip coefficient testing of bolted connections are conducted in Slip Coefficient Testing of ASTM A709 Grade 50CR Steel and Dissimilar Metal Slip-Critical Bolted Connections, a report from the Virginia Department of Transportation. The goal of this report is to determine how a specific steel bolt fits into the current bridge design specifications. Online Program EventThe purpose of this study was to conduct slip coefficient testing of bolted connections made from ASTM A709 Grade 50CR steel to determine how they fit into the current AASHTO LRFD Bridge Design Specifications surface condition classifications. Relaxation in High-Strength Bolted Connections Using Results showed that unblasted Grade 50CR steel has a slip coefficient value of at least 0.30, meeting the current AASHTO Class A surface condition for unblasted steel.
