When you first click the gable wall tool you will be presented with the following gable wall matrix:



As you can see from the shading all wall types except for the "Gable" type have been grayed out.  Initially I will make only this wall type available, then the "Shed" will be the next type I proceed to develop.  The rectangular, gable and shed walls constitute the vast majority of wall geometries used in most construction however you can see there are quite a few other possibilities, so many in fact, that I quickly ran out of descriptive names to assign them.

Compared with a standard rectangular wall a gable wall with have the following additional parameters:

- Wall Height Left
- Wall Height Right
- Wall Pitch Left
- Wall Pitch Right

These four parameters will drive the location of the wall peak.  In most situations the left and right values will be the same resulting in a symmetric gable wall however any combination of dissimilar pitches and wall heights will be possible which will then yield an asymmetric gable wall.

The wireframe preview will look like this:



In this case we have a symmetric gable wall.

I'm going to have to dumb down some of the more general features/parameters found with rectangular walls as they apply to gable walls.  For example with rectangular walls you can have walls connected at non-orthogonal corners.  For gable walls this becomes very complicated and eventually I will probably allow it however for now I think it would be best to limit gable walls to ONLY orthogonal connections at the corners.  If I don't do this it will be another 6 months of programming before I ever complete the gable wall module.

As I was testing asymmetric gable walls earlier today it became apparent that the intersection at the peak is a little more interesting with the asymmetric case.  Also I will probably make the double studs positioned at the peak an optional setting in the global settings.

Notice how the door falls beneath the gable wall peak:



In this situation the symbol or outline for the opening must be broken into two faces as shown.

There are a lot of little details like this that further complicate things having to do with gable walls, finding them all is a slow and meticulous process.

Working on in-wall columns for gable walls:



A full height column just butts up to the underside of the top plate(s) and is cut at a bevel to match the pitch of the wall as shown.

A more interesting scenario is where the column is less than or more than the plate height and you might then have a beam pocket, in this case at the peak of the wall:

A bit more to do with the framing but it appears to be mostly there now, notice the mid-span blocking algorithm will need some additional logic:


The critical items still needing further attention are:

- Cavity insulation
- Mid-span blocking
- Sheathing, Cladding, Gypsum
-  Ext. Trim: Corner Trim, Band Board, Frieze Board
- Quoins
- Beam Pocket cut outs (sheathing, cladding, gypsum)

The future items that will need to be addressed at a later date are:

- Estimating quantities for Gable Walls
- Framing dimensions for Gable Walls
- Simpson Strong-Walls

Looks like we have the mid-span blocking firing on all cylinders now:



Notice the california corner still needs to be beveled where it abuts the top plate, I guess I missed that one earlier, I'm on it.

After that I will work on the cavity insulation.

I will release the gable wall to the public once I have completed the previous checklist, I will keep posting updates as I complete each item.  The ETA could be in a as little as two days or it could be as far out as two weeks depending on if I run into any specific roadblocks along the way.  You never know until you dig into the code.

I'm not sure if I've got this right and I need to make sure it is right.

Shown below is an exterior gable wall forming an outside (orthogonal) corner with an exterior rectangular wall, probably the most common configuration that will be encountered with gable walls.



The gable wall terminates with an outside corner and the rectangular wall terminates with an inset outside corner.  Does this look correct?

If we were to reverse the terminations (gable -> inset outside corner and rectangular -> outside corner) how then should the corner look?

Here is what I am proposing for the reverse case where the gable wall forms the inset outside corner:

We're not out of the woods yet:



The WSW series is field trimmable (to an incline), so we can set that up if this type of pre-manufactured shearwall is selected. I also need to add some extra logic in for the optional king studs and the symbol on top of the wall.
Nathaniel P. Wilkerson, P.E.

Medeek

A WSW Simpson Strong-Wall trimmed to an incline to fit within a gable wall.  I've been looking forward to this day ever since I utilized one of these shear wall panels within one of my own residential designs about four years ago.



Note that only the WSW series can be field trimmed like this, at least to my knowledge.  I need to do a bit more research into what Simpson recommends for an SSW installation when the top plate is inclined or if this is even possible.  I suppose one could always install a trapezoidal block between the SSW and the top plate.

Next I will look at the sheathing, cladding and gypsum and also sort out more of the details with the inset outside corner (termination).
