how much wind can a house withstand? triple-bricked solid home built late 1892. 150-300 mph/km?

Answer 1

The real question is not what wind it could stand but whether it could stand the things the wind is carrying and slamming into it. I don't believe any measured natural wind has measured as high as 300 mph, but the house would have to be standing in isolation to encounter just a wind. Once winds get over 100 mph in roughly a straight line (as in a hurricane) or higher but tighter (as in a tornado) things like signs, trees, pieces of bill boards, parts of neighbors' roofs, etc. are going to be launched at the house. Could the house withstand a car going 100 mph - probably not.

Answer 2

Tough question. Here's why.

The direction the wind hits the house matters. If it hits broadside to a wall, the pressure is much more than if it hits oblique, at a corner.

The weak part is usually the roof. Once this goes, the inside of the house now presents more surface area for the wind to 'grab'.

Another consideration is debris carried by strong winds. Now you can have a 2X4 moving at 100 kph hitting the brick wall.

Water carried by the wind also increases the effective 'impact'.

Look at hurricane proofed houses on the web for ways that these things are addressed and to get a rough estimate. Also, remember that the older the house, the weaker the mortar between the bricks becomes. You have probably seen this as cracking between the bricks.
