used for the code checks and modeling of associated bridge elements. Bolt properties defined in this section will be assigned to relevant components, such as splices, at a later stage.

Geometric Properties

Bolt

Diameter [0.625/0.75/0.875/1/1.

125]: Nominal diameter of the bolt used in design. The design only supports the given options for bolt diameter, and entering a different bolt diameter is not supported.

The definitions related to bolt geometry can be specified by defining parameters below:

Diameter of

the Head: The diameter of the top section of the bolt can be specified using this parameter.

Diameter of the

Nut: The diameter of the nut section of the bolt can be specified using this parameter.

Thickness of the

Head: The thickness of the top section of the bolt can be specified using this parameter.

Thickness of the

Nut: The thickness of the nut section of the bolt can be specified using this parameter.

Mechanical Properties

Grade of Bolt Material [A325/F1852/A490/F2280/A307_GradeA/A307_GradeB]: The type of material used for the bolt determines the shear resistance of low strength bolts and the minimum required bolt tension for high strength bolts.

Is Bolt Slip Critical? [Yes/No]: Option to specify the mechanism by which bolt force is transferred. This parameter turns automatically into ‘N/A’ (Not Applicable) in case a low strength bolt grade is selected.

Hole

Type [StandardHole/

OversizeHole/Short-SlottedHoles/Long

-SlottedHoleswithPerptoForce/Long-SlottedHoleswithParaltoForce]: Affects the reduction factor for bolt holes in determining block shear rupture resistance.

Punched or Drilled Hole [PunchedFullSize/DrilledFullSize]: Bolts can be specified as either drilled or punched. This parameter will be used for design of related elements.

Bolt Thread [Excluded/Included]: The type of bolt is determined by the position of threads relative to the shear plane and impacts the shear resistance of the bolt.

Surface Condition [ClassA/ClassB/ClassC/ClassD]: Related to the slip resistance of bolts. Refers to the condition of the faying surfaces, such as being unpainted and clean, blast-cleaned with a coating, galvanized, etc.

Visual Settings

Number of Segments Used to Draw the Bolt:The "Number of Segments Used to Draw the Bolt" refers to how many discrete parts or segments are used to represent a bolt in a graphical or computational model.
