How to create Revit model automatically?


 

It happens when you run ICDAS Add-Ins in Revit, or on

Dynamo scripts. ICDAS Add-Ins is run on family files. You will

work on both of Revit family and Revit project file. ICDAS apply

Revit family file 2D and 3D for the deck, and 3D for the piers

and the abutments.


Once the bridge 3D is automatically created in Revit, one can

create any 2D section on the bridge, drag to a predefined sheet

for the documentation. When the 3D bridge is updated, all 2D

section drawings will be updated in all sheets accordingly.

 

 

 

 

 

What type of concrete bridges and how to change

shapes of the deck, pier, and abutments?

 

ICDAS COB 2017.00R allows you to create concrete bridge with

slab deck, box deck or prefabricated TT-slab with concrete

topping.


To change shape of the deck you can e.g. modify input from

slab to box deck and create it automatically in Revit 2D family

file. Once done, press "Load into project" to update the new

deck cross section into the bridge 3D file (Revit project file).

 

To change shape of the pier you modify the input for the pier,

create the pier automatically in Revit 3D family file. Once done, 

press "Load into project" to update the new created pier into 

the bridge 3D file. The same procedure applied for the two

abutments.


Once you run Revit Add-Ins for a new updating input, a new

*.cmd file is updated accordingly in your working folder.


Import this *.cmd file in Lusas for your analysis model.

Using ICDAS COB depended on cases of alignment and cross section?

 

ICDAS COB provides three options for creation of the bridge deck geometry depended on case of alignment,

cross section and about 3D reinforcement in concrete bridge deck. The three methods are known as ICDAS Revit,

Civil Structures and Dynamo BIM4Struc V1.2.1. All are useful for bridges with curved alignments. In case of

rectilinear alignment, or circular arc the first option is fastest since you can directly work on Revit interface using

ICDAS Bridges Manual without the needs of Civil Structures and Dynamo scripts. In all cases, you need to enter

ICDAS input for the analysis model in LUSAS, if needed.  

 

Case of alignments and bridge deck cross sections for the Revit geometry model are listing below. 

 

ICDAS Revit

 

The road corridor is not needed as input for the deck geometry, so far the alignment is rectilinear, or circular

arc in Floor plan, and the longitudinal profile has a slope, but not a curved line. You can directly create the deck

in Revit relative coordinate. Then assign global coordinate and angle to the true north at Revit Project Base Point,

 normally the start point (station) of the deck, at the STL center of the cross-section. The case of curved alignment,

(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.

 

This option allows unlimited number of slopes on top of deck, and any needed profile of cross section incl. box

girder. See example for this option.

 

ICDAS 3D reinforcements are OK with Dynamo scripts the case of curved bridge deck.

 

 

Revit Civil Structure

 

Revit Civil Structure 2017 needed to be in integration with Civil 3D for creation of the bridge, incl. abutments
and piers. You need at least in Civil 3D to design the road corridor overpass (or import an existing terrain model
from MicroStation InRoads/InRails). Note that Revit need only the road corridor overpass from terrain model (the
road center line STL, the left edge line and the right edge line as the two inner lines of the two edge beams. And
the thickness 110mm of the road corridor as the pavement above the concrete deck created in Revit). Revit can
also detect the road underpass and geometrical surface, but not necessary for creation of the bridge where the
underpass levels of the pier foundations can be input manually. See example for this option.

 

3D reinforcement need some additional works for using Dynamo scripts (ICDAS Manual)

 

 

Dynamo BIM4Struct

 

This option requires the road corridor as described above, but provide only one slope on each side of the cross

section, p.t Dynamo V1.2.1. There is no pavement created on top of concrete deck but the deck is positioning in

parametric distance below top of pavement (e.g. 110mm)See example for this option.

 

ICDAS 3D reinforcements are OK with Dynamo scripts.

 

 

For all cases ICDAS Bridge Libraries provide further a large options of foundations, piles, piers, and bearings which

are predesigned ready to load into any project file.
