StructuralSteelPlateVehicularUndercrossing

The StructuralSteelPlateVehicularUndercrossing subassembly inserts links and shapes to create a Structural Steel Plate Vehicular Undercrossing based on Caltrans Standard Plan B15-1 and Contech Construction Products, Inc.

You should verify that the dimensions used match your interpretation of the standard plan and Contech Construction Products requirements.

Attachment

The attachment point is at the bottom of the Structural Steel Plate Vehicular Undercrossing subassembly.

Input Parameters

Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default
Size	Span and rise size dimensions	S12'2''xR11'0'' / S12'11''xR11'3'' / S13'2"x11'11" / S13'10''xR12'3'' / S14'1''xR12'10'' / S14'6''xR13'6'' / S14'10''xR14'0'' / S15'6''xR14'4'' / S15'9''xR15'1'' / S16'4''xR15'5'' / S16'5''xR16'1'' / S16'9''xR16'3'' / S17'3''xR17'0'' / S18'4''xR16'11'' / S19'2''xR17'2'' / S19'6''xR17'7''	S19'6''xR17'7''

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Daylight Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Optional

Runtime Logical Assignments

Dimensions for the Structural Steel Plate Vehicular Undercrossing are set from the user selected input parameter.

Output Parameters

None.

Behavior

The initial point is set at the attachment point. If the daylight surface is below the plate bottom or above the rise dimension, the entire steel plate is built. If the daylight surface is within the interior of the steel plates, then the steel plate is partially constructed. Each plate angle is split into 10 sections comprising 10% of the plate angle. The sections are then tested until the daylight occurs within the section and no further processing of the sections occurs.

Layout Mode Operation

In layout mode, this subassembly draws the Structural Steel Plate Vehicular Undercrossing.
