the Wall connections problem

Bartolomej
Contributor

I'm having trouble keeping proper connection between 3 walls with differing finishes. The connection pictured on the left should not behave like this because of priority of building materials. Junction order is equal, changing it makes it only get bugged in different way. The junction on the right is what I'm aiming at - but it's only 2 walls.

Also - wall heights are the same and no connections above or beneath.

Hello Bartolomej,

 

I insist that you try to modify the reference line of your shear wall. Maybe if you place the reference line on one side or the other can change the connection between your three walls. There is nothing complex or difficult to accomplish.

Hello Bartolomej,

 

I invite you to try to modify the wall reference lines to get your aim.

A 3D view a be useful to understand your wall height subject.

The problem is the junction is working properly in 3D, just 2D representation gets buggy. I don't understand why. I'd rather avoid modifying reference lines since im trying to apply walls with different composites to make conceptualizing easier - using different reference line modes is probably going to make it unnecessarily complicated at this point. I just don't get why styrofoam covers masonry, since it's building material priority is lower

By your 3D view I can see your wall reference lines seems to be good.

Did you try to modify display order of the shear wall ?

Display order doesn't seem to change anything - connection exists but is weird - as in attachment

 This occurs with all triple wall connections in this project - 2 wall connection works perfectly fine.

Yeah, this way it works, however I still would prefer to keep references in cores because I'm probably going to remodel the whole thing a few times until it comes to final version. But still - good to know how to make it work.

Or, to make it easier to work with reference lines - is there a way to change reference line without changing wall positioning?

There is a trick were you create a custom profile column and place it in that corner to make sure everything looks correct.

I am having exactly tha same problem. 3 wall junction and the walls a behaving very strangley. I really dont know what to do. I have checked materials strength, wall priority, reference line.

 

Why is the adjacent wall affecting the interior skin of the composite wall that it is joined to like this???.

 

Unfortunately it is happening on several wall junctions, in both 2d and 3d.

it's all about reference line location and bMat priority. Put the reference line on the inside face of core for the horizontal wall

thanks. Pretty sure I tried all the reference line positions. But will try it tomorrow.

if you can send me a .mod of the walls, I'd be happy to test it out and fire it back to you tomorrow some time... I've done a few blog posts on it and had several training sessions. It's one of those things that can be super finicky... sometimes you need to force an offset that is even OUTSIDE the wall thickness to get it clean. https://wwabim.wordpress.com/2019/11/15/wall-junction-trouble-shooting/

That would be very much appreciated! This has brought the project to a bit of a standstill until I find a solution.

I will prepare the file later today and send you a download link.
