APPO 3.0 Powerpoint Template.Albert CanalPROJECT INTRODUCTION: In the context of removing the capacity limits for the Albert canal it has been issuedthat all bridges must be redesigned in order to have a minimum vertical clearance of 9,10m.In the beginning of 2014, 28 bridges of 61 were already executed, 33 other bridges were in progress of design. The ambition is to finish the bridges by 2020.Theunis bridge was built around 1960 and is located on the N129 route. It is situated northeast of the city of Antwerp, in the district Merksem and it represents the link between Antwerp-North and Deurne.This urban bridge is surrounded by industrial and residential areas.3

GENERAL INTRODUCTION: The Albert canal is the main canal in Belgium.Each year, there are more then 40 million tons ofgoods transported. The canal connects the port of Antwerp with the industrial area of Lige.

Bridge designFunctional program:Tramway with connection to the subway.Road design 2x2 lanes, speed: 50km/h.2 Bicycle - and pedestrian lanes.

Dimensions:Canal widening until approx. 90m.Bridge span of +/-110 meters.Bridge width of 50 meters.- Multiple bridges easier to build in phases.



EnvironmentImpression under the bridge:Transform the old bridge area into an urban social environment.

Impression near the bridge:Create an experience for traffic and residents.


APPO 3.0 Powerpoint Template.8VISUAL PROGRAMMINGTheunis Bridge

Visual Programming For BridgesAfter analyzing the complexity of the model and the software tools possibilities, Dynamo and Grasshopper (as a visual programming tools) were chosen in order to generate the bridge in a parametric manner. A collaborative design process was set in place that would ease the process and increase the efficiency

Structural Design

STRUCTURAL ENGINEERINGStructural analysis has been performed by the mix Belgian-Romanian team and the design software of choice was SCIA. The physical structures and their components have been designed to withstand all necessary loads to ensure safety, reliability and integrity.SCIA cross-section files have represented also an entry point for the Dynamo generation algorithm. Cross-section outlines have been made by injecting SCIA cross-section fibers values directly into Dynamo,

APPO 3.0 Powerpoint Template.Civil3D

ROAD ENGINEERINGBridge architecture was made in Cinema4D and Civil3D. The provided 3d model was accurate in terms of road outline and bridge main design shape. From Civil 3d we extracted 3d-polylines that were exported as a set of points in CSV. We injected these points in Dynamo to have our main guidelines.

Several stage were identified at the beginning of the design process and a logical design schema was set in place. The design was intended to be a multi-disciplinary, multi-user development process.

Project Structure[Civil exports][Dyn][PlatingGeometry][SciaSectionExport][xmlgeometry]A python script was written to read the section files (the scope is to fast adopt it to other projects)Cross-Section Dimensions - SCIA

01READING INPUTAll existing data were read and not remade. This kept up certainty with input values

Small configuration data and implementing the script in Dynamo and we have the local coordinates of our cross-section.The data for Longitudinal Beams and diagonals were read using these files.Data for Transversal Beams were manually written in the definition15

03CONFIGURING EACH BRIDGEGeneric definitions have been adapted to particular situations

External python scripts have been made to be used without structure change

Using dynamic generic programming, dynamo files have been used for all 3 bridges successfully after copying the files to the right folders, changing the folder input data paths and making some particular changes for the bridges.

To change the entry data we just change the path to where the data is stored:22



04EXPORTING TO REVIT

Bridge components have been exported from Dynamo to Revit and linked together with other components made in Revit (foundation elements).
