Welcome to ICDAS Add-Ins for automatic creation of Concrete Bridges (COB).

This section and links on the left menu give a brief introduction for working with automatic model creation of Concrete
Bridges. ICDAS creates information model in Revit and analysis model in Lusas by reading Excel input. 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 COB 2018.01R, the following software are needed:

 

›  ICDAS COB 2018.01R

›  Revit 2018.2

›  Dynamo V1.3.2 (free in updated Revit 2018.2)

›  AutoCAD Civil3D 2018

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

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

 

ICDAS Concrete 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.

›  BIM for reinforced concrete incl. detailed 3D reinforcement design and report to Excel for quantities calculation.

›  Detailed modelling of prestressing tendons  incl. recess, anchorage head, bursting reinforcement and so on.

 


On the same time, ICDAS automates also LusasCOB.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 LusasCOB.cmd file

 

›  Geometric points, lines, surfaces as the Revit geometry model

›  Shell elements represented concrete deck with 1m step along the bridge alignment

›  Single load cases on bridge for pedestrian bridges, road bridges and railway bridges

›  Smart combinations of single load cases, and envelopes of the smart combinations in SLS and ULS according to

   Eurocodes and National Annexes.

 

ICDAS COB provides three types of concrete cross section, either massive slab deck, box-girder or prefabricated

T-elements combining with concrete topping. The bridge alignment can be curved or double curved.


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.

123456789_123456789_1123456789 

  
Table: The three options for automation of concrete bridges

Options

Alignment & cross section

ICDAS Excel input

Option 1


ICDAS Revit

 

 

Bridge
Example

 

Required software

   ICDAS COB 2018.01R

   Revit 2018.2

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


Option 1 is powerful when the bridge alignment is rectilinear or circular arc. ICDAS provides both of Revit and Lusas models automated concurrently. The bridge is designed at (0,0,0) in both where the global coordinate will have specified in Revit Project Base Point and updated ongoing with project.


Bearings, piers, foundations and piles can be loaded to project from ICDAS libraries


 

3D reinforcement & varying cross section

Free Form Rebar Distribution from Revit 2018.1 allow the user to create rebar in 3D views by selecting the concrete faces to which the rebars are aligned.


ICDAS COB automations are currently available for massive slab deck with the same cross section along alignment.


For box-deck and varying cross sections along the bridge alignment you can easily follow ICDAS REVIT BRIDGE MANUAL to create bridge within a short time, incl. bearings, piers, foundations and piles from ICDAS libraries.



Lusas model

'LusasCSB.cmd'. Only for rectilinear or circular arc alignment.


Remarks

You need to create the underpass corridor.

 

Input for Revit and Lusas model for massive deck with 4 for 6-bottom-lines examples are in sheet Bridge and STL.

 

For prestressing deck the cables curve are configurated in sheet CableCurve, which will be copied in Lusas > Bridge tab > Prestress Wizard manually.

 

 

There is special input for bridge deck with  prefabricated TT-elements combining with concrete topping for Lusas model (as Additional features)

Option 2


Civil Structure

in Revit


Bridge

Example

Required software

 

as in Option1, and


   Civil Structure 2018 in Revit (not yet released from Autodesk

   pt. 06-01-2018)

   AutoCAD Civil 3D

 

Option 2 allows any curved alignments of the bridge overpass and the road underpass, where Revit is in integration with AutoCAD Civil 3D. The bridge is designed using Revit Civil Structures addin and known as Revit Bridge Extension (REX).

 

Bearings, piers and foundations are built-in in REX libraries.

 

3D reinforcement & varying cross section

Free Form Rebar is not available for the deck as mass family

has been employed for the deck in Civil Structures.


The deck cross section is constant along the bridge alignment.


Lusas model

'LusasCSB.cmd'. As in Option 1.

 

Remarks

Civil Structure 2018 in Revit is not yet released from Autodesk pt. 06-01-2018.

 

You need to customize special ICDAS family files being use in Civil Structures. Instructions are including in ICDAS REVIT BRIDGE MANUAL.

 

Option 2 includes also underpass corridor and be comparable with Civil 3D for terrain modes or landscape model in 3ds Max.

Input for Revit special 2D deck cross section, 3D piers and foundations which are not found in Autodesk REX libraries. They are in sheet Bridge & STL.

 

 

Inputs for Lusas model are as described in the Option 1, but for rectilinear or circular arc alignment only.


123

Option 3


Dynamo

BIM4Struct

in Revit

 

Bridge

example

 

Reinforcement

example

Required software

 

as in Option1, and


   all latest packages of Dynamo for Bridges outlined

   in ICDAS Dynamo Manual 2018.01


Dynamo needs (X, Y, Z) points for RoadTopLeft, RoadTopRight and RoadTopCenter needed. This corridor points are created from Civil3D/Bentley for the bridge overpass.

 

Global coordinate is OK.

 

Bearings, piers, foundations and piles loaded to project from ICDAS library using ICDAS Method. 

 

3D reinforcement & varying cross section

›   3D reinforcement OK with Dynamo scripts.

›   The deck cross section is constant along the bridge alignment,

     and only massive deck is available pt. COB 2018.00R.

 

Remarks

›   You need to install Dynamo, study the flow of data, and

     where to change the input in ICDAS Manual.

›   This method allows many input of corridors. For a selected

    corridor, the bridge deck immediately will be created. This

    method is fastest for complicated alignment which needed to

    adjust during the project.

Bridge Corridor created from Civil3D must be stored in Excel sheet Bridge Corridor of ICDAS input.

 

Inputs for Lusas model are as described in the 1nd option.
