Geometry control

ABES geoDes

ABES geoCon

ABES assemCon

Geometry modeller for segmental bridges.

Geometry control during segment production in the casting yard.

Geometry control during bridge assembly on the construction site.

ABES geoDes

• ABES geoDes assists in defining segmental bridgeswith a great degree of detail and precision.


ABES

6

ABES geoDes

• Deck geometry based on road or rail alignments usingfirst principles in plan view and elevation.

• Alignements consist of straights, clothoids, arcs inplan; and arcs and parabulas in elevation.

• Unlimited number of alignments.

• Secondary alignments at variable 3D offsets possible.

• Selected locations along axes for connection withabutments, piers etc.

• Alternative input using pre-processed alignment datainstead of first principle alignments.


ABES

ABES geoDes

• Parametric cross-sections with variablemeasurements along alignment. Cross-sections toadapt in geometry according to the position along thealignment.

Alignment intersection with cross-section plane.

Control points for subsequent geometry control in ABES geoCon.

ABES geoDes

• Segments: match-cast segments, pier segments, castin-situ segments, wet joints etc.

• Each segment can be defined to great detaildepending on segment type.

• Joints can be at free angles to alignment in plan andelevation.

• Modelling of diaphragms or blisters etc.

• Fixed length, or adaptive segment length.

• Match-casting against one other segment plusbulkhead, or conjugate segments at both sides.


ABES

ABES geoDes

• Segment groups defined for typical segmentsequences (e.g. typical cantilevers, typical spansetc.).

• Segment groups are placed on alignments to form thebridge structure.

• Individual segments can be placed as a tangent orsecant to the alignment (or transition between thetwo).


ABES

10

ABES geoCon

• ABES geoCon is used at casting yards to supportgeometry control of pre-cast segments in short-linematch-casting.


ABES

11

ABES geoCon

• ABES geoCon supports setting out of casting cells.

• Adjustment of conjugate segments to achieve desireddeck geometry.

• Correction of casting errors surveyed in previoussegments.


ABES

12

ABES geoCon

• Correction of casting errors using a novelmathematical approach.

• Corrections can be distributed over several segmentsif required.

• No limitations of the number of control points.

• Control points can be placed anywhere on the cross-section;

• and can be placed anywhere within the segment.

• Innovative algorithm provides instant feedback andoptimum results.


ABES

13

ABES geoCon

• Horizontal match-casting typical for bridge decks.

• Vertical match-casting for piers or pylons alsosupported.

Visualisation of Nipigon bridge in Canada.

Match-casting of pylons to be supported by ABES geoCon.


ABES

14

ABES geoCon

• Optional functionality to support management ofcasting yards.

• Unlimited number of casting cells.

• Unlimited number of survey stations.

• Input of casting yard layout including positions ofcasting cells and survey stations.

• Tracking of casting yard layout in case of re-positioning of casting cells or survey stations.

• Book keeping of which segments are cast in whichcasting cells, and which casting cells are occupied andwhich ones are free.


ABES

15

ABES assemCon

• ABES assemCon is used on the construction site tocontrol the bridge geometry during assembly.


ABES

16

ABES assemCon

• ABES assemCon assists in the assembly of pre-castsegments at the construction site.

• Setting-out of starter segments.

• Geometry forecasts.

• Integration of segment-to-segment monitoring data.

• Optimisation of shims or other corrective measures.

• Consideration of as-cast data, pre-camber andconstruction sequence.

• Book-keeping of as-built geometry, and geometryevolution throughout construction.


ABES

17

ABES Software

• Open architecture allows for compatibility with othersoftware platforms.

• Cut & paste of input and results tables to Excel orother spreadsheet software.

• Spreadsheet data can be pasted directly into ABESinput screens.

• Automated report output in table or pdf format.

• All geometry data can be exported to .dxf format forfurther processing in CAD packages.
