Welcome to software for automatic creation of Arch Bridges, ICDAS AB 2017.00R

 

This section (and sections on the left menu) is a brief introduction to working with automatic model creation

of Arch Bridge. It describes the basic methodology and is not contained all ICDAS tools and descriptions.

All examples are generic for worldwide use and do not conform to specific company standards. Refer to a

ICDAS licence for more details on all parameters and guides to your project.


To automate geometry and analysis models, you need licence for the following software

(Window 7 and 8 operative system):

 

§      ICDAS AB 2018.00R


§      Revit 2018 (also available on 2017)


§      Lusas Bridge V15.2-5 (also on previous version)


§      Input Excel or normal text file. For Excel both of format *.xlsx

      and *.xls are available, (*.xlsx with 1048576Rows*16384Columns).

      Alternatively, NotePadd++ is recommended for text input (freeware code editor). 


 

ICDAS REVIT BRIDGE*.rvt template is needed. Currently only EU cross sections are added in Revit families

folders. For user outside of EU, the user-defined cross sections are useful  for numbers defined in ICDAS

inputfile.

Geometry model

 

ICDAS AB 2018.00R create geometry model automatically in Revit from Excel (or text) input file. Levels of all

hangers at the arch are also automatically layout at all elevation views.  Once 3D geometry model is obtained

in Revit, the user can create all 2D sections for drawing dimensions. The bridge is created in relative coordinate

at origin (0,0,0) for both of Revit and Lusas models. Once the absolute coordinates are know, the user can replace

the origin point with (X,Y,Z) in input, and run the model again. All created 2D drawings and sheets will be updated

accordantly. See link on the left for further details.

Analysis model

 

When create geometry model in Revit (by run ICDAS add-ins in Revit) a Lusas*.cmd file is also created. Import this

file in Lusas, the user will obtain analysis model (FEM) created automatically. The FEM model is also included loads

on bridge in case they are activated in input (the first UDL is non zero).

 

 

Cross sections

 

Steel Frame deck require many sizes of cross sections. ICDAS compare libraries of cross sections from Revit (USA)

and Lusas (UK). Both have predefined EU, Australian and Canadian cross sections including other countries standard.

However, many EU cross sections of large sizes in Lusas do not found in Revit families. ICDAS has established these

families in template ICDAS REVIT BRIDGE*.rvt in accordance with Lusas FEM. Thus, by running ICDAS add-ins in

Revit, both of Revit and Lusas model will apply the same cross sections for creation of geometry and analysis models.

 

 

Load model

 

Automatic loads creation free your time to define and assign loads on bridge. Further, single loadcases, basis
combinations, envelope of single loadcases, envelope of basis combinations, smart combinations and final envelope
of smart combinations in Lusas are all automatically created. It is ready for you to analyse and document the bridge
