Generic Wall Design for Single Wythe Loadbearing Walls,
Volume 1
In
1995 the Masonry Institute of Michigan established a
committee to develop generic masonry wall details.
The primary goal of the committee was to create "user
friendly" masonry details for the design community.
The economy and functionality of these details will
compliment masonry's inherent quality as a durable building
material.

Wythe - Blok-Flash® |
| BLOK-FLASH®
is an embeddable flashing pan for exterior single wythe
C.M.U. wall systems. It collects moisture that infiltrates
the wall and flows down the vertical cores and diverts
it to the exterior. BLOK-FLASH® is a single wythe
CMU flashing system that is useful at all flashing/weep
hole locations including base of wall, above door and
window openings, above bond beams, in parapet walls,
basements and any other locations where flashing is
necessary. |

Lap Splicing |

Calculating
correct rebar lap splicing to meet code...
The IBC 2006 adopted MSJC 2005 by reference; however they
decided to keep the previous lap lengths of 48 bar diameters.
...that engineers may have the option of using MSJC 2005 for
their design lap lengths. Depending on the f’m the lap
lengths can be shorter particularly in the smaller bar sizes.
...Footnotes (1) & (2) represent comments in the IBC code.
(1) instructs the engineer on additional lap requirements
in areas of high stress, (2) addresses the requirements for
epoxy coated rebar. Footnote (3) assumes the bars are spaced
at least 8” on center if the bars are closer the table
will need to be adjusted. All bars are centered in the wall,
if the bars are designed off center the table will need to
be adjusted. The f’m is a variable that may
be changed to meet your project requirements. The IBC 2009
has adopted MSJC 2008 including the lap lengths. These laps
match the MSJC 2005 requirements so the MSJC laps should be
what we see in the future.
Below is a lap splice spreadsheet, provided by Kelly Walker
of the Masonry Institute of Michigan, which has been updated
for IBC 2006 as adopted in MBC 2006. Also below, are the MSJC
2005 laps.

Approximate
spacing of Control Joints (CJ’s) for reinforced
CMU...
Using the Empirical Method in NCMA TEK 10-2B, Table
1 calls for a length to height ratio of 1.5 not to exceed
25ft. This assumes you have wire every 16” o.c.
The engineering method in NCMA TEK 10-3 has different
ratios but still does not exceed 20 or 25 ft.

| The
2008 Masonry Wall Cost Guide is intended to provide
users with an in-place wall square footage cost for
145 wall assemblies for six cities in Michigan: Ann
Arbor, Detroit, Flint, Grand Rapids, Lansing and Saginaw.
The
870 listed costs are provided as an aid to assist
decision-makers in utilizing masonry economically.The
figures represent total masonry cost including labor,
material, overhead and profit. All masonry wall costs
were based on a straight run wall with no openings.
The cost will be greater when considering openings,
corners, site conditions, material handling conditions
and weather. Wall heights vary and were based on applicable
design methodologies as noted.
