Brick Lintel load

[JStructsteel]

See attached. Have a precast lintel over a opening with brick above. Was trying to figure out the load to the lintel, as there are some other precast 'banding' thru the brick. Was trying to be conservative, but not too conservative. See attached for my thoughts on the load I should use.
Thanks

Maybe get rid of the rectangular portion of your load and just use the triangular distribution.

...and use a couple of L4x4 HDG loose lintels.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?

XR250 do you mean as the blue triangle I've marked up?

I'm inclined to agree with the original markup in red, not forgetting to include the load(dead and live) from the concrete planks and floor span they represent.

@MHobbs

That is decorative concrete banding, not planks. This appears to be brick veneer.

Its a decorative banding, but I wasnt sure I would get arching action thru the joint in the middle. I went with my original red line, so I am conservative.

I think the red lines are another example of masonry being overdesigned. While it is good to be conservative at times, especially when you aren't familiar with a material, certain principles always exist. Arching action occurs with masonry when laid in running bond. The joint in the precast band shouldn't affect arching action since the joint can't open or close due to the surrounding masonry. If you were to take the brickwork out within the blue triangle, the precast would stay in place since it extends back into the masonry on either side. In fact, due to the long nature of the precast band (if the joints are shown accurately), it would change the load distribution into the brick below it and might even relieve some additional weight off of the steel angle. I'm just talking about veneer here and loadbearing plank/concentrated loads may be a different story.
