Maybe I'm misunderstanding, but a brick veneer wall shouldn't be loadbearing. It can transfer wind loads to the backing, but it shouldn't be a part of the roof support system. Can you transition to a loadbearing block wall beneath the limestone veneer that runs to a support on the foundation? Or...
Of course, the easy answer to this is - don't support the masonry veneer on the wood at all and let the canopy be self-supporting. :) I do feel that in the past, supporting brick on wood in any way would be a cause for concern from a fire standpoint. That mentality isn't as evident today, not...
I want to be careful when discussing this topic since it matters whether you say "supported on" wood construction or "supported by" wood construction. It seems like you are talking about an application of brick veneer being supported on top of wood construction (even if the actual bearing...
The masonry industry is trying to get some input from structural engineers on how they design masonry beams and lintels. Please take a few minutes to fill out the short survey below. It will be a great help to advance masonry codes (US centric). Thanks!
As part of a project funded by the NCMA...
There are a few ways to verify the strength of a brick wall (or do you mean brick unit since you mention 3000 psi?). As ANE91 pointed out you can cut prisms out of a wall. There are ASTM standards that discuss proper removal, but as ANE pointed out, the labs may not be familiar with that. You...
Repointing (not tuckpointing) is a pretty universal term for replacing old mortar with new mortar. People do have an issue when trying to deal with smaller cracks that may go through the brick - sealant? mortar? leave it alone? No universal answer and as the comments above state, cracks that go...
ASTM C1196 is a pretty sophisticated test and only firms like WJE, Atkinson Noland and WDP & Associates have that capability. Doing impact echo testing is a possibility, but getting the right calibration is critical. Hamid and Schuller's book has a lot of good info on NDE of masonry...
Trained mason contractors know the correct way to grout a masonry wall. The TMS 402/602 clearly shows the requirements for cleanouts and these types of issues are discussed at contractor seminars and events. IMI has a certification for reinforced and grouted masonry that craftworkers can take...
At what point should you consider going with a CMU backing instead of a stud wall? At 24' using a 8" block, the amount of vert reinforcing can be minimal and you would get a more robust wall. If you are going with an 8" deep stud that would have the same footprint as a block wall.
Sulfate attack is rarely a problem with masonry, especially on the clay brick side. Most of the deterioration occurs in the mortar and if it does happen in the brick it takes decades for issues of salt crystallization to cause problems. Concrete masonry could be more susceptible, but I rarely...
Yeah, ditch the precast and do a true loadbearing arch. Pham provided one of the BIA Tech Notes, but here is one that is a little newer (on arches in general): https://www.gobrick.com/media/file/31-brick-masonry-arches.pdf. and for those that can't get enough of masonry arch design...
I don't know of any requirements in TMS 402 (ACI 530) regarding this, but it is often good practice to have the thicker wall below be grouted at least at the top course. This gives more bearing area for the thinner wall since you would only have thin webs supporting the wall (potentially). If...
