Design Conclusions
For
The IMSI� Insulated Masonry Wall System
I
Insulated Masonry Systems, Inc.
completed extensive s#ructural testing to provide
data. for reliable design with the IMS11' Insulated
Reinforced Masonry Wail System. Testing
involved 54 wail sections measuring 4' x 4', 8' x
8` and 8' x 16'4" showing predictable results.
Full-scale destructive testing was
conductedin the Civil Engineering department of
Brigham Young University under the supervision
of Dr. Arnold Wilson according to the
Acceptance Criteria for Concrete and Concrete
Masonry Systems, 1987 ICBOP
Additional non-structural testing was
done at Northwest Testing Laboratories for
determination of infiltration and sound
transmission characteristics of IMSI (N watts.
Testing of insulation material used was
done by the manufacturer at various laboratories.
Product Description
Testing Summary
The following summary of test results
presented to simplify the designer's task begins
with some facts about the unique nature of the
wall system.
1. fMS1A' blocks are dry -staked without mortar.
2. The IMSI k -R
asymmetrical
eight inch wide block has an
cell confguration, therefore
eccentrically placed with the
and grout closer to one face
reinforcement is
reinforcing steel
than the other.
Specifically:
A. From the face closest to the outside of
the wall, d = 5.5 inches.
B. From the face closest to the inside of the
waif, d = 2.5 inches.
3. Steel reinforcing used 'n the testing was two
#4 (1/2 inch) deformed bays in each grained
reinforcement cell. Different reinforcement
schedules were tested. However, after initial
testing of 8 foot by 8 foot samples, reinforcement
was on a 4 foot Vertically, 4 foot horizontal
schedule which is considered the minimum
reinforcement schedule.
Surface bonding cement in all testing
and for all applications is always applied to both
sides of the wa!l to make walls water tight and
for aesthetic reasons.

4. All ungrouted hollow block cells are filled with
polystyrene insulation inserts,
The structural tests
conducted include:
1. Flexural testing per ASTM E 72 - 84 for
both d-5.511 and d=2.5".
2. In plain shear per ASTM E 519-81 and
ASTM E 564-76,
3. Flexural compressive tests per ASTM E
72 - 804 d= 5.5" and d= 2.5".
4. Compressive Testing with Eccentric
loading per ASTM E 72 - 80.

According to ASTM Standards, block
compression and block prism tests were
Performed. For block, the Average Gross Area
Strength was 1917 psi. Average Net Area
Strength was 4008 psi. Two Block Prisms were
dry -stacked with no mortar Or surface bonding
cement. Prism tests yielded Average Grass Area
Strength 1247 psi, Net Area Strength 2609 psi.'
