Welcome to ICDAS Add-Ins for automatic creation of Cable-stayed Bridges (CSB).

 

This section and links on the left menu give a brief introduction for working with automatic model creation of Cable-stayed Bridges. ICDAS creates information model

in Revit and analysis model in Lusas by reading parametric input in Excel file. The Excel file is also an output where data from Revit and Lusas models are written back

for further calculations. To work with ICDAS options for CSB 2019.00R, the following software are needed:

 

 ICDAS CSB 2019.00R

 Revit 2019

 Dynamo V1.3.3 (free in Revit 2019)

 AutoCAD Civil3D 2019

›  Lusas Bridge V17.0-0c4 (also available on previous version)

 Excel or Text editor (NotePad++ freeware code editor)


To use Virtual Reality in Revit LIVEyou need VIVE VR System where computer graphics NVIDIA GeForce GTX 1060 (or above) and all other requirements (HTC Headset) are listed in the link.

 

ICDAS Cable-stayed Bridge provides high level accuracy project design using Revit intelligent model-based technology for the following benefits:

 

3D model is created as the basis of all associated 2D sectional drawings, which are

  updated dynamically for changes of 3D model.

3D Pylon with 8-points cross section

Any 2D profile of deck for 3D creation of massive deck using Revit Civil Structures

The power of ICDAS Revit Bridge is that, the users can change ICDAS family files

   for a new bridge in no time, and all family files are stored in one project file.

 

On the same time, ICDAS automates also LusasCSB.cmd file to be imported in Lusas for the FEM model (based on parametric input from Excel file). The following automations are currently coded for LusasCSB.cmd file

 

› 3D streamlined steel box girder of deck in shell elements

› Inclining pylons in beam element (tapered cross section assigns manually)

› Automatic cable arrangement for a given section length and spans lengths.

 

ICDAS CSB provides either streamlined steel box girder (default) or concrete box girder.

 

There are further three options for creation of Revit and Lusas bridge model in ICDAS. 
In short, they can be called ICDAS, Civil Structures and Dynamo, respectively.
However, the last two options still need family files from ICDAS Option 1 (default) and the three options can be combined. All options will start from Revit summarized below.

Table: The three options for automation of cable-stayed bridges.


Options

Alignment, steel and/or concrete deck

ICDAS Excel input

Option 1


ICDAS Revit


Example 3

 

Example 2


 

Required software

›   ICDAS CSB 2019.00R

›   Revit 2019

›   Lusas Bridge V16.0-1c1 (also previous version)

 

Option 1 is default for rectilinear alignment of cable-stayed bridge. Both of Revit and Lusas models are automated concurrently.

 

Revit model

'ICDAS_Generic_3D_Deck.rfa'

'ICDAS_Generic_3D_Pier.rfa' (Pylon)

 

Pylon incl. stayed cables, streamlined deck and ribs, bearings, piers, foundations, and piles are loaded into project files as for ICDAS bridges. ICDAS provides library for family files manual on how to use it.

 

The bridge is designed at (0,0,0) for both of Lusas and Revit models. A global point assign to Revit Project Base Point from which the entire bridge is changed to global coordinate accordingly.

 

For concrete approach bridge refer ICDAS COB. 

 

Lusas model

'LusasCSB.cmd'

Rectilinear alignment and streamlined steel box deck is default. For concrete box with walls the input still can be used with some modification.

 

Remarks

You need to create the underpass corridor manually.

 

There are unlimited number of top and bottom lines creating the deck.


Distances and slopes for top and bottom lines are in BRIDGE sheets.

 

Pylon and cables are inputted in BRIDGE sheets.


Spans and section length are inputted in STL sheets.

Option 2


Civil Structure

in Revit


Example 1 

equired software

 

as in Option1, and

 

›   Civil Structure 2019 in Revit (free addin from Autodesk.

    Not yet released pt. 19-06-2018)

›   AutoCAD Civil 3D

 

Option 2 provide global coordinate for the bridge overpass and the road underpass, where Revit is in integration with AutoCAD Civil 3D (curved alignment). Civil Structures is for concrete massive slab deck and concrete box deck by default.

 

Revit model

'ICDAS_Profile_2D_Deck.rfa' (streamlined steel deck to customize in Civil Structures)

 

Pylon incl. stayed cables, bearings, piers, foundations, and piles are loaded into project files as outlined in Option 1.

 

Note that Civil Structures use mass family for concrete deck which cannot host rebar. 3D reinforcement (Free Form Rebar) is therefore not available.

 

 

Lusas model

'LusasCSB.cmd'. As in Option 1.

 

 

Remarks

You need to customize ICDAS family for streamlined steel deck. Instructions are including in ICDAS Revit Bridge Manual.

 

Option 2 includes also underpass corridor where the users can check Revit model with terrain model in Civil 3D.

Same as Option 1 for the deck 2D profile, 3D pylon & cables.


Spans length define in ‘Bridge definition’ in Civil Structures  


Input for spans and section length in Excel are for Lusas model only.

123

Option 3


Dynamo

BIM4Struct

in Revit

Dynamo has not been yet tested in ICDAS for streamlined steel deck of cable-stayed bridges.

 

 

Refer ICDAS COB for concrete approach bridges
