Lusas V16.0-1c1 new 3D perspective view and Revit Live 2.0 require both graphics memory for testing on 300m length cable-stayed bridge above. ICDAS has run them both (and Revit) and found out that the monitor is updated significant faster if one of the modes is shut down. Lenovo laptop i7-3720QM CPU 2.6GHz 32GB RAM and graphic adapter NAVIDIA Quadro K2000M 2GB RAM has been used. Refer VDC hardware and wearable devices for further information. However, Lusas and Revit work smoot concurrently during automation test in wireframe visual style and realistic visual style in Revit without attention.
Revit LIVE 2.0 Revit LIVE is not needed in ICDAS CSB but it is recommended to subscript it in Autodesk AEC Collection. Revit LIVE graphical visualization and Virtual Reality is the future and already applied in many companies today. When you orbit and fly in Revit LIVE scene the first time there are some notices below: - The Revit model Danube2018.rvt tested here is only 6.724MB. The ‘Go Live’ button create a so-called live-scene file Danube2018.lvsc of 436MB, a folder Danube2018* of 486MB and a folder Danube2018*_data of 3.19GB. The two big folders include maybe i.a. Virtual Reality technology. Once upload on the cloud, you can save the live scene *.lvsc and associated folders anywhere in an external hard drive. The scene is on the cloud where you can open it anywhere from any PC/Laptop with Revit LIVE and internet connection, and without the need of Revit model.
- You cannot move the model physically (as in Lusas or Revit) but fly around it. It is especially unusually to focus on the bridge with big length-to-width ratio compared to a square building. - Language codes for Revit LIVE is maybe in internet programing, unlike normal language for working on local PC/Laptop. You can enter your scene anywhere from any PC/Laptop by sign-in in your cloud service account.
The images with cloud background are from Revit LIVE.
Design with ICDAS automation is best to work with both of Lusas and Revit concurrently. ICDAS CSB has coded Lusas model first then use to Revit. Some dimensions need to measure and some additional help-lines sketch in Revit to find a common input for both of models. Lusas FEM analysis is useful to design as well, e.g. at pylon-deck clash. Below are some images for working with ICDAS CSB.
Revit model The pylon, cable arrangement and deck can be easily modifying by parametric input for a new look. For symmetric bridge the design time is reducing to a haft since a mirror copy take no time in Revit. The figure below has only taken time to enter parameters in Excel input, run addin in Revit and upload the model on Revit Live. The detailed work for pylon-deck clash is implementing manually and easily. 
Figure: Revit model uploaded on Revit LIVE cloud service. ICDAS CBS automates the outer contour of streamlined deck where the internal thicknesses will be designed manually with ICDAS Revit Manual. For double symmetric bridge deck, the user only need to create thicknesses on the left haft of the deck cross section, then copy mirror to the right haft, as shown below. 
Figure: Streamlined steel deck with stiffening ribs unloaded from family files.
ICDAS provides library of stiffening ribs for different sizes and shapes for rectilinear alignment streamlined steel deck. Further, the users can apply the step-by-step ICDAS Manual to model new ribs and add to the library (Revit family files). ICDAS CSB is including concrete bridges (COB) for approach bridges and the cable-stayed deck can be in concrete as well, e.g. in combination of concrete-steel-concrete for side, main and side span. The cable-stayed concrete box deck need some input manipulation outlined in Cable stayed bridge User's Manual.
Lusas model Easy to identify each group of elements in the bridge Together with automatic creation of the FEM model, ICDAS automates also groups for pylons, cables and plates for each group of the streamlined deck box in Lusas Groups and Attributes tab as shown below.
Figure: Check thicknesses of plates creating streamlined deck girder.
The users can e.g. check thickness 16mm for every 2nd cross plates at the cables, by right-click on the attributed names and ‘Select Assignments’ shown above, for the left and the right cross plates. Pylon-deck clash 
Figure: Split deck surfaces and delete at pylon.
The figure above has set visible only 4 sections of the deck at the pylon leg where the right haft top of deck plates is set invisible. By default, ICDAS automate all nose plates along the deck. The users can easily delete them at the pylon, manually. It can be done by Lusas splitting surface in parametric distance (into two surfaces in this case). Set 4/7 for section on the side span, and 3/7 on the main span as all longitudinal surfaces has X-axes in the bridge STL direction. There are 7 elements mesh in these surfaces and factor 3/7 successfully fit the needed space. Otherwise, set parameter between 0 and 100% length of the section. Once splitting, just delete the nose surfaces at the pylon. The case of vertical pylon, more space is needed at the deck in cross direction. Therefore, the designed line L3 (and R3) are to create surfaces to be delete at the pylons. In this case they are 1100mm from line L2 (and R2). Thus, the emergency lane 3000m reduces to 1900mm at the pylons. All distances input for line L1, L2…, R1, R2… are specify in Excel input file. |
