Hello,

I have a 11.5cm (4.5 inches) thick intermediate wall made of calcium silicate bricks in my garage. I want to install a frame for a 200kg (440 lbs) battery on it. The frame would be fixed using threaded rods that go through the wall. Is there any guideline on how much load a 11.5cm (4.5 inches) thick calcium silicate brick wall can support?

The garage partition wall made of calcium silicate bricks is 6m (20 feet) high. At heights of 2.2m (7.2 feet) and 3.8m (12.5 feet) there is a ring beam. In between are the calcium silicate bricks. The frame is flush against the wall and attached to the masonry with four threaded rods (10mm / 0.4 inches). All threaded rods are continuously screwed into the ring beam. What kind of load can such a wall with ring beams withstand?

Oh, you better ask a structural engineer, statics expert, or master mason about that.
From my perspective, it should be sufficient, as concrete ceilings with additional load-bearing capacity are also resting on it.
However, I don’t know if your roof is still on top with wind load, snow load, and dead weight.
Is the foundation designed for the wall, or is the wall just standing on the slab?
200kg or 800kg is quite a difference.

There are no concrete slabs placed on top. A reinforced strip foundation is located beneath the 11.5cm (4.5 inches) calcium silicate brick wall.

I still maintain,
800 kg is too much as a preliminary diagnosis.
