Reinforced Concrete in Autodesk Revit - Rebar Cover

 

Autodesk Revit software provides tools for modeling 3D concrete reinforcement in an advanced Building Information Modeling (BIM) environment.

 

This series provides insight into how to use these tools in the best way for creating complete, detailed, and accurate reinforcement design. You will learn how to use the standard reinforcement modeling, drawing, and scheduling tools.

 

In the first series of steps, you set up rebar covers.

 

• Reinforcements are added to concrete structural members based on the design reinforcement. In Autodesk Revit, you can add reinforcements to concrete structural members such as floors, beams, columns, and others by using various tools. In Revit you can model regular reinforcement and wire fabric reinforcement. There are a number of categories assigned for these reinforcement types, and they all behave and interconnect differently. Before we actually start using the rebar tools, we should have a short look at an important setting for all our reinforcement: The Rebar Cover Settings. The cover settings define the offset distance of the bars from the face of the rebar host.

• Go to the Structure tab and locate the Reinforcement panel. Expand the drop-down box and click on Rebar Cover Settings.
• Rebar Cover Settings is a simple dialogue where you can add all the different covers you need in the project. Find the existing XD1\XC3/4 (C32/40,0.55,320) cover and change its value to 30 mm and click OK.
• On the Structure tab click the Cover button. The Cover tool is used to edit the cover settings in the entire length of the host of a rebar. The host of a rebar can be a beam, column, slab, floor, or a generic object.
• On the Options Bar, click Pick Elements to pick an entire element.
• Select all beam elements which will be modified and change their cover to XD1\XC3/4 (C32/40,0.55,320) then press the Esc key.
• Select one of the beams and review the cover settings in the Properties dialog. It's important to get the cover settings right because all (well, almost all) modeled reinforcements are slaves to the cover. The Cover Settings can of course be changed in your model over time, but experience shows that this can disrupt your model and schedules.
