Any tool or method to find Structural Framing's Bearing length (Column)

[Arciviz]

Total Length = Bearing Length Left/Top of Column + Cut Length of Structural Framing + Bearing Length Right/bottom of Column.

How to find Bearing Length Left/Top of Column / Bearing Length Right/bottom of Column.

1'6" & 9" are bearing length as shown in the attachment.

Please explain how you determine these through the user interface.

I suggest you start by exploring how to achieve what you are trying to do manually through the user interface.

If that is possible, it is probably possible programmatically as well.

Thank you!

Cheers,

I have to rebar for Str.Columns, Str.Frames & Slabs using Revit API.  Our company has our own shape code & tag style.

Now I want to find beam's both side bearing length (Please refer extension - Reinforcement - "beam.png").

Also refer our "LSD - Beam.png".

Any method to find easily. or Having any existing code to find bearing.

I have no idea off-hand, so I forwarded the question to the development team for you.

Hi Mr.Jeremy,

Thanks for your valuable replay.

Hi @Arciviz,

I am not exactly sure what are you looking after. Do you mean the size(length) of the volume in which the beam intersects a column?

[jeremytammik]

Is this what you mean?

A beam may rest on two columns.

The columns may have sticky out bits supporting the beam.

How long are the sticky out bits?

Or, alternatively, how long is the bearing length of the beam, the unsupported length?

Cheers,

Jeremy

[Arciviz]

Yes

[Arciviz]

Sorry, I am little Poor in English.

A beam may rest on two columns.

1. Intersection length of Endpoint(0) of beam & Column 

2. Intersection length of Endpoint(1) of beam & Column 

any method to get Length?

[Arciviz]

Intersection Length. Column's Width or breath.  Example - 1'3" is bearing length  (refer attachment LSD Beam.Png)

[dragos.turmac]

I see, so my assumption so correct. Now, the next question is more specific:

do you want the code to work only in the case of rectangular beam/column that are intersecting in 90 degrees angle?

Because there are a plethora of other situations that can't be defined in the same code and they can be vastly more complicated to detect (circular column + rectangular beam = variable length, rectangular beam + rectangular column at a non 90 degree angle from X axis = variable length, etc.)

[jeremytammik · Accepted solution]

You could use one of the numerous methods to determine the columns supporting a beam listed here:

http://thebuildingcoder.typepad.com/blog/2013/03/supporting-columns.html#2

Once you have the beam and supporting columns, retrieve their geometry, and determine the distance between the two closest vertices with each vertex belonging to a separate column.

You could also use the ReferenceIntersector to shoot a ray parallel to the beam location line, offset just below the bottom of the beam.

That would return the two closest column faces.

Cf.:

• http://thebuildingcoder.typepad.com/blog/2014/11/determining-intersecting-elements-and-continued-fut...
• http://thebuildingcoder.typepad.com/blog/2010/01/findreferencesbydirection.html

The Revit SDK sample FindColumns demonstrates how to find columns that are embedded in walls using the ReferenceIntersector.

You could use a very similar approach to determine the columns located just below the beam.

Super Dear Jeremy.

Thanks lot.

I Have try it. Some case it work. Some case it leaves nearest column and rays next column.

View CurView = ui_doc.ActiveView;

XYZ dir_st2end = curve.GetEndPoint(1) - curve.GetEndPoint(0),

// Filtering StructuralColumns
