27 feet high brick (clay) masonry wall
wind load will be 20 psf and reinforced beam are resting at every 12 feet with 63 kips reaction. any tips?
check out our whitepaper library.
run and hide?
or make the wall thick enough to meet code requirements of aci 530.
it sounds like it is in place since the beams are resting on it.
what are the details of the wall construction? - thickness, number of wythes, reinforcement?
if it is not in place, a reinforced block wall with a brick veneer would be more econoomical and have the same appearance. try to distribute the beam loads throughout the length of the wall, rather than deal with vertical "columns".
more details would help give better suggestions.

it is not in place but needed brick masonry. what is the minimum width for this height as per aci 530
impossible to give any imtellegent answer with out more information.
if you need a brick exposure on one side and can tolerate another surface on the other side, a reinforced block bearing wall with a brick exposure will be the most economical, since you can pack a lot more steel into the wall for strength purposes.
i am sure you realize your problem is with the wall height and distributing the column loads. if the wall was only 8' high, you could go 20+ stories with just a 6" block wall.
dear concretemasonry
i need to use brick masonry for some reason.
ll on roof = 20 psf.
wind load on side walls = 20 psf
building foot print 50' x 200 '
so rcc beams are spanning 50'. hence reaction becomes 63 kips factored.
building is not built yet. but walls have to be brick masonry and slab rcc.
single storey building.27 feet high to give 24 feet clearance.
3 feet deep concrete beams.
can 12" thick reinforced brick masonry be ok. use #8 @ 12 " c/c and o.c.
thanks.
i suggest doing an engineered design using aci 530, which is applicable to both concrete and clay masonry. the engineering requirements are well-documented there. additionally, you may want to do some research on brick construction. the brick industry association has numerous tech notes for clay masonry construction (
does anybody have spread sheet to design this
dgkhan, you will just have to check the design against the accepted masonry code in your area. if it doesn't work the first time, you will have to adjust your design and recheck until it does work. for example, if the masonry does not work at a thickness of 12 inches, you may have to increase the thickness. if the reinforcing does not work at the spacing and size you check, you will have to adjust it and recheck. there may be several aspects of the design to calculate, check and adjust until you have a final design that meets both the client's needs and the building code.
note that we cannot answer your question about a specific size and spacing.
given the very specific appeance/wall onstruction requirements, i doubt that you will be able to find a spreadsheet that will work for your project. this is not a common construction method for walls having your configuration. you will have to resort to a design according to aci 530, based on your wall section and heights.
if you have to match an existing brick (probably a typical modular sized brick), your wall construction becomes limited to load bearing brick wythes on either side of a grouted cell. this gives you a small "d" (about 5."), which is a problem with the wall height. this type of wall also imposes constructability restraints, tight specifications on the grouting and inspection, plus a cost burden.
if you are allowed to use an oversized engineered brick (limited selection), you could design a double wythe bonded reinforced brick wall that could have a greater "d" distance.
some preliminary calculations could help you make some decisions on the practicality of the diferent wall possibilities. after that, you can address the actual structural design, load distribution, details and the construction challenges.
