As many of you may already have seen, Revit Structure 2013 is now shipping and has a host of new platform features as well as some specific new features to Revit Structure 2013. Rather than create a huge post showcasing all the new features I thought I would break this down into separate sections.

The rebar has been a constant feature that has been updating for the last few years and each step Autodesk get nearer to a full solution for detailing. This release brings new functionality to the following areas:

  • Improved snapping and alignment
  • Rebar Units
  • Area and Path reinforcement (Hosting of Rebar)
  • Fabric Reinforcement

Standard mesh reinforcement can now be added to slabs, walls and foundation slabs using a boundary. Revit Structure 2013 will automatically trim the sheets and can give cut lengths and widths for each sheet if required. The bars are modelled in 3D and also are represented in plan with tagging and sectional views. The full UK standards for wire mesh are included within the standard Structure template as well as tags and labels to detail the sheets in plan. Lap lengths can also be set as well as the ability to stagger the sheets or set half way passing.

The path and area reinforcement tools have also had a bit of an overhaul and can now generate 3D rebar. The path option will create bar perpendicular to the path and can use a range tag to detail the bar in a plan view.

Autodesk have also added some improvements to the creation of bar within bends and hooks allowing the snapping to quadrants and 45deg positions.

OASYS GSA 8.6 link to Revit Structure 2012

GSA Analysis is a highly intuitive tool from ARUP, enabling users to carry out 3-D linear, P-delta, non-linear static analysis, dynamic analysis and more. GSA 8.6 now links with Revit Structure 2012 enabling engineers to import models from Revit Structure 2012 to GSA 8.6. You can also import a GSA 8.6 model directly into Revit Structure; however, this will have some limitations.

I have set up a simple test which is shown below. GSA took through the Grids, Levels and all structural objects. Below you can see the model in Revit Structue 2012.

Here is the same model transferred to GSA 8.6. Note that the transfer should be made from the Add ins tab in Revit Structure.

Understanding Concrete Beam Joins

A few weeks back I was asked how Revit Structure handles concrete beam joins and how to control and manage how beams are connected and processed at the junctions. In older releases of Revit the beams would always mitre which was good in some cases but in other situations really didn’t give the correct solution. I have now modelled the various configurations and created some images so you can see how the beams will join. If you do want a mitred junction which is not 90 degrees then you will need to use a precast material.
