Welcome to ICDAS Add-Ins for automatic Concrete Bridges creation.

 

This section and links on the left menu give a brief introduction for working with automatic model creation of

Concrete Bridges. ICDAS create geometry model in Revit and analysis model in Lusas based on Excel input data.

The Excel file is also an output where data from Revit and Lusas models are written back for further calculations.

To work with COB 2017.01R, the following software are needed:

 

›  ICDAS COB 2017.01R

›  Revit 2017

›  Civil Structures 2017 (Revit Extensions, free add-on to Revit)

›  Dynamo V1.2.1 (free add-on to Revit)

›  AutoCAD Civil3D 2017

›  Lusas Bridge V15.2-5 (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 update dynamically for changes

   in 3D model.

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

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

 


On the same time, ICDAS COB create also analysis model in Lusas based on the same Excel input. The following

automations are implemented for Lusas model:

 

›  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

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


There are three options for using ICDAS COB depending on alignment and cross section of the bridge. These three

options can further be combined. The table of options below helps the users to select the option which suited best

for the project case.

Options

Alignment & cross section

ICDAS Excel input

ICDAS Revit

 

 

Bridge
Example

 

There are no needed for alignment data from Civil 3D if the alignment is rectilinearity or circular arc. Otherwise, (X, Y, Z) points report needed for 1m step wise along the center alignment. This report is created from Civil3D/Bentley for the bridge overpass.

 

The global coordinate specified at the end of design process at Revit Project Base Point.

 

Bearings, piers, foundations and piles are loaded to project from ICDAS libraries.

 

3D reinforcement & varying cross section

›   3D reinforcement OK for using Dynamo scripts directly.

›   Any profile of deck incl. box girder, also varying along the    

    bridge alignment.

 


Remarks

›   You need to create the underpass corridor.

›   This method is simplest for the bridge overpass, especially

    when the alignment is rectilinearity or circular arc. You can

    easily follow ICDAS manual to create a double curved bridge

    deck within a haft of hour, incl. bearings, piers, foundations

    and piles from ICDAS libraries. There is no needs for Civil

    Structure or Dynamo installed add-ons in Revit.

 

There are input for Lusas model for massive deck with 4 for 6-bottom-lines in sheet Bridge and STL.

 

Automation of Lusas model are only available for rectilinearity, or circular arc alignment, curved or double curved, pt. COB 2017.01R.

 

For prestressing deck the cables curve are configurated in sheet CableCurve.

 

For verification of concrete and reinforcement, sheet ‘Fc ULS’ and ‘Eurocode SLS Crack’. The verification apply sectional forces from Lusas.

 

There is special input for bridge deck with prefabricated TT-elements combining with concrete topping for Lusas model.

Civil Structure

in Revit


Bridge

Example

Bridge overpass and road underpass are in integration with terrain model created from Civil3D.

 

The bridge is designed in the so-called Revit Bridge Extension (REX).

 

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

 

3D reinforcement & varying cross section

›   3D reinforcement need some additional works for using

     Dynamo scripts.

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

 

Remarks

›   You need to install Civil Structure, customize special family

    files in REX structure with guidance from ICDAS Manual.

›   This method includes also underpass corridor and be

    comparable to terrain model in Civil 3D or landscape model in

    3ds Max

There are ICDAS input for special 2D deck cross section, 3D piers and foundations which are not found in REX libraries (sheet Bridge & STL)

 

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

Reinforcement

example

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

 

Global coordinate 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 2017.01R.

 

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 sheet Bridge Corridor.

 

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