Shearwall with Window opening?

Shearwall with Window opening?

Shearwall with Window opening?

(OP)
I generall design shearwalls having door and window openings as a series of shorter walls from opening to opening.

Is there a way to consider them full length with perforations?
If so, are there design references or suggested methods of analysis?

RE: Shearwall with Window opening?

Check out IBC2006: Section 2305.3.8 Shear Walls with Openings as a start.  Section 2305.3.8.2 Perforated Shear Walls is what I generally use.

RE: Shearwall with Window opening?

There is a popular approximate method for analyzing shear walls with openings.  I read a paper recently that found that the method wasn't very accurate.

RE: Shearwall with Window opening?

If your wall is more opening than wall, you may want to analyze as a rigid frame, not a wall.  i do this where I have shear walls that have so many large openings that all that is left is a grid of beams and columns.  So i run it as a rigid frame and come up with the reinforcing and deflections that way.  Seems pretty reasonable to me.

Our situation is just an access hatch between normal stud spaces.
 

RE: Shearwall with Window opening?

I believe the IBC has some provisions for perforated shear walls where you use the % of wall as openings rather than design each element around each opening as a separate pier.

What kind of shearwall...concrete, masonry, wood stud, metal stud?
