Rusted Beam Advice
Rusted Beam Advice
(OP)
I am a private building inspector. My job is to find structural and mechanical problems for my clients and to prescribe appropriate action for them to resolve the problems I find.
In this case, I will advise a structural engineer to have a look.
This is a 60 year old building and this is the only place I see that the rusted steel beam is causing problems, that is, buckling masonry.
In general, what sort of repairs and cost might my client be looking at? Steel replacement? Steel repair depending on how much rust?

The masonry is not buckling. This is a crack related to the faulting at the ledge angle.
You need to have a structural engineer look at this, as you have noted.
Next, I don't mean to be unkind, but if you are going to be in the business of inspecting structural components, you need to learn a bit more about structural systems. You need to understand what "buckling" means and you need to understand what a beam is. You have mischaracterized both in your description.

The vertical separation between two adjacent angles indicates problems with the fasteners of the angles, so I would say complete replacement of the wall support will be required.

2. Somebody has already tried to fix the wall by repointing the joints and by platering over areas of the brick.
3. The cracks appear to be from settlement.
4. The wall is built off a cantilevered floor and the floor may have deflected excessively.
5. The difference in level of adjoining steel lintels supporting the brick facade is helping to propogate cracking. It appears the difference in level of adjoining lintels is due to poor original construction.
6. As previosly stated by others wall ties may be in poor condition considering the condition of the supporting angles. The condition of ties can only be assessed by opening up areas of the wall and having a look.
7. I do not think the wall needs to be demolished and replaced but remedial measures are necessary. The steel lintels do not appear to be rusted to the extent where they need to be replaced although it is impossible to be sure by looking at a couple of photos.
8. Some possible solutions could include raking out mortar joints and installing bed joint reinforcement. Another solution would be remove some bricks and weld a steel vertical flat plate to the top of the steel lintles supporting the brickwork to make the brick and supporting lintles act compositely.
A solution may involve strengthening the cantilevering steel or concrete beams that form the support to the overhang (1st Floor) as these beams are possibly deflecting excessively.

The steel may not need to be replaced, but it must be inspected by a structural engineer. It might be beneficial to cut control joints in the brick veneer at each of the vertical strips.

This stuff is like detective work - you are often looking for tiny almost insignificant things that are out of place. These things are usually overlooked by someone who does not have an in depth understanding of the workings of buildings.
What I am trying to say is that you really should get an experienced structural engineer on site to have a look at it. All comments on this site are just mere speculation based on the limited information that you have provided, information that may not cover the crucial clues to the causes of the issues.
