AASHTO LRFD COMPOSITE STEEL GIRDER BRIDGE GIRDER MATERIALS

  • Structural steel – base element
  • Connections – bolt nominal stress
  • Connection bolts – tensile strength requirement
  • Connections – min. bolt pretension – clamping
  • Bolt torque
  • Connections – weld
  • Weld quality
  • Shear studs
