Define general information about the girder
Select the construction events for this girder.
Item | Description |
---|---|
Construction | Select the event when this girder is constructed |
Erection | Select the event when this girder is erected |
Define the girder type.
Item | Description |
---|---|
Girder Name | If unique girders are used throughout the bridge, select the name of this girder from the drop down list. Click on the combo box control to change how girders are defined in the bridge. |
Define the concrete properties.
Item | Description |
---|---|
f'ci | Enter the concrete release strength |
Eci | When checked, enter the modulus of elasticity at release. Otherwise, the modulus of elasticity will be computed by the AASHTO equation. |
f'c | Enter the design concrete strength |
Ec | When checked, enter the design modulus of elasticity. Otherwise, the modulus of elasticity will be computed by the AASHTO equation. |
[More Properties...] | Press to define detailed concrete properties or select a pre-defined concrete from the library |
Use the combo box to control how slab offsets are defined for the bridge.
Item | Description |
---|---|
Start of Girder | Enter the slab offset at the start of the girder |
End of Girder | Enter the slab offset at the end of the girder |
Enter the Assumed Excess Camber for this girder. The assumed excess camber is used to define the parabolic haunch depth used for computing haunch dead load.
Note that this option is only available if the parabolic haunch load option is selected in the current Project Criteria library entry. Refer to the Slab Haunch loading section of Structural Analysis Models for more information about how the haunch dead load is defined.
Select the condition of the girder from the drop down list. If "Other" is selected, enter the condition factor.
