reinforced wall masonry for dummies

reinforced wall masonry for dummies

(OP)
i have Zero masonry experience. i have to do a reinforced masonry wall about 15' high, 30' long. wall loads are just selfweight and wind.

looking for a basic detail drawing and reference do design this.

thanks,

Is this a cantilever? Because a 15 ft tall wall (not even coursing, by the way) is pretty tough to design.
Amrhein's "Reinforced Masonry Engineering Handbook: Clay and Concrete Masonry", Fifth Edition is your best resource.

yes, cantilever. reinforced cmu. this is just a wall to separate two equipments. while i can probably do the calcs, i'm also looking for some go-by drawings how is this shown in 2d drawings.

Plan and section really, plan shows length, section show height, foundation and reinf. Could show dowels in plan, so they dont forget them :)

You can download from the below link the Brick Industry Association CAD Details

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

i was able to get a copy of "Reinforced Masonry Engineering Handbook: Clay and Concrete Masonry 6th ed"

i would probably need a go by drawing as i'm lost where to start. i dont even know the available types of cmu to use in the market.

Search some NCMA information. Many masonry suppliers have their own NCMA document that shows the available sections and their properties that should give you a good start. using f`m of 1500 psi is probably a good starting point too.

Also get your hands on ACI-530, which will have more information as well.

Jim Amrhein's book is very good, and is widely used and accepted, but his "sponsors" were unfortunately allowed to add a few local practices. Some of those items were not used in the creation of the state of the art national standards, which Jim also helped to write.

Another pair of a resources and the premier masonry document, ACI 530 and the engineering manual that usually is used in parallel and distributed as part of the package used at seminars conducted by various organizations (ACI, NCMA, TMS and various masonry promotion groups. I don't have a copy of the manual with me now, so the exact title the big, heavy book has some very good examples of different situations and problems applicable to all areas (geographically, seismic and wind) and is commonly used in many countries.

In masonry design, the important thing to remember is that you are designing a wall and not just different products. If you arbitrarily grout all cells full even if they have no reinforcement, you change the character or the wall, so distribution of loads, and stresses will not agree with the the assumptions made in the development of the codes, standards and any tables since they are based on the f'm of a hollow block prism that can have a wide variation depending on local block available and the block configurations.

YOu might consider using pilasters at 10' o/c with 8" CMU's ad reinforce the 16x16 pilasters for the moment...
