© 2011 Autodesk Class Summary This class will present an overview of SOFiPLUS, an interface for structural analysis based on AutoCAD® and explain how it complements Autodesk® Revit® Structure. You will learn how to maximize benefits from Revit Structure 2012 by leveraging its new analytical model. We will also discuss the importance of working with partial models (slabs/shear walls, etc.) and code checking for single parts of the building (columns, slabs, etc.).

© 2011 Autodesk Learning Objectives At the end of this class, you will be able to:  Use the analytical model of Autodesk® Revit® Structure for structural analysis with SOFiSTiK FEA  Work with partial models such as slabs for more accurate analysis  Understand the workflow of code checking software using a Revit model and results from FEA  Create reinforcement drawings using results from the SOFiSTiK design and geometry from the BIM model.

© 2011 Autodesk Step 3: Completion in SOFiPLUS

© 2011 Autodesk Properties not currently available in Revit  Must be defined in the analysis software  Must be repeated after each export from Revit   -> Modify in Revit as much as possible  More properties available in Revit in the future?

© 2011 Autodesk Step 5: Export and Analysis of the Slab as Subsystem

© 2011 Autodesk Refined analysis with partial systems  Not possible/desired to perform all design tasks on the entire model  Slabs as 2-D-systems  Membrane forces not desired  Design against shear forces needs finer mesh  Area loads have to be applied in several load cases  Columns  Design against lateral and torsional buckling

© 2011 Autodesk Automatic generation of support conditions

© 2011 Autodesk Supporting rectangular beam  T-Beam-Section needed for Design  Increased stiffness not desired  Complex algorithm necessary to obtain realistic stiffness AND correct design results  Can be controlled by parameter “SOFiSTiK Effective Width”

© 2011 Autodesk Step 6: Code Checking - Design of footings

© 2011 Autodesk Code checking  Support forces from SOFiSTiK database  Geometric information from Revit  Design of footing  Import new object and rebars

© 2011 Autodesk Step 7: Detailing the slab

© 2011 Autodesk Flow of data

© 2011 Autodesk Geometry from Revit  Prepare a sheet with views in Revit  Export to SOFiCAD  Master drawing for defining rebar objects  External references with the geometry  Modifications  New external references  Adjusting rebars manually

© 2011 Autodesk Design results from analysis  Indication of required reinforcement  Automatic reinforcement layouts  Loose bars  Meshes  BAMTEC ®  Manual layout  Basic reinforcement  Reinforcement still required

© 2011 Autodesk Conclusion

© 2011 Autodesk Conclusion  The BIM philosophy is not a simple concept  BIM is supported very well by existing software  There is still some room for improvement  Thanks for listening  Q & A
