Define the connection boundary conditions and geometry at a pier.

NOTE: "Back" refers to the back on station side and "Ahead" refers to the ahead on station side of the abutment/pier.

Boundary Condition

Use the drop down list to select a connection boundary condition.

Connection Definition

Define the geometry of the connection. Press [Copy Connection Geometry from Library] to copy pre-defined connection geometry from the library.

Girder Connection Properties

Define the geometric parameters that locate the centerline of bearing and ends of girders. The schematic image illustrates how the dimensions are measured.

Item	Description
Bearing Offset	Distance from the abutment/pier line to the centerline of bearing line. Use the drop down list to define how this dimension is measured.
End Distance	Distance from the centerline of bearing line to the nearest end of the girder. Use the drop down list to define how this dimension is measured.
Support Width	Total width of the support (bearing). This dimension is always measured along the centerline of the girder. The support is assumed to be centered on the centerline bearing. The face of support for various shear releated computations is located one-half of the total support width from the centerline bearing.

Diaphragm

Defines the geometry of a cast in place diaphragm.

Item	Description
Diaphragm Height	Height of the diaphragm. Enter the keyword "Compute" to have this value computed based on the girder size and connection geometry.
Diaphragm Width	Cross sectional width of the diaphragm. Enter the keyword "Compute" to have this value computed based on the girder size and connection geometry.
Load Application	Use the drop down list to define how the weight of the diaphragm is applied to the model.
Distance from Abutment/Pier Line to C.G. of Diaphragm	If "Apply weight of diaphragm to girder" is selected for the load application option, this parameter defines the distance from the Abutment/Pier line to the center of gravity of the diaphragm.
