How Do You Tell If Is Or Shear Strength Unreinforced Masonry

But engineers and civic leaders have known for decades that one type of structure will, indeed, be reduced to rubble: old brick buildings. If a building remains unreinforced, it’s at risk for collapsing walls and “peeling” of masonry elements. Even relatively light shaking can trigger crumbling debris and further damage. These rows of bricks turned endways every 5-6 rows provide added stability to unreinforced masonry. Behind the cover plate, do you see brick or other masonry?

If the structure was built prior to 1940, there’s a much greater risk that it is not reinforced.

Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Yet little has been done to require owners to retrofit or even warn occupants that the walls around them are likely to collapse in a major quake.

and the city doesn’t have a ready source of money to subsidize the costs. If you cannot tell by looking at the outside of your building, go to the electrical outlet box. Looking at the building from the outside, you’ll see that the end brick, or particular rows of bricks, are facing a different direction than the majority of bricks.

It is more difficult to tell if a concrete or concrete block building includes reinforcing steel. Solutions to reinforcing masonry include adding a steel frame that is bolted to the wall or tying the walls to the floor and roof.

First photo is what you see with your eyes and what the digital camera see. Second photo is what the infrared camera sees. The infrared camera will tell you those right locations, then, if you want to scan for steel, do so. Try to make sure it is stated correctly and understood correctly? Northwest is still not prepared for the magnitude 9.0 megaquake and tsunami in our future.
