1. During the construction of a reinforced concrete masonry shear wall in
a multi-story commercial building located in a high seismic zone of
California, the project inspector observes that the mason has placed
vertical reinforcement bars directly against the inside face shell of the
concrete masonry unit without maintaining the specified grout cover.
According to accepted structural masonry practice and California
building code requirements, what is the primary structural concern
associated with insufficient grout cover around reinforcement within
masonry walls?
,A. Increased thermal expansion of reinforcement leading to wall bowing
B. Reduced bond strength and inadequate corrosion protection for
reinforcing steel
C. Excessive shrinkage of mortar joints resulting in veneer cracking
D. Increased compressive strength of the masonry assembly causing
brittleness
B. Reduced bond strength and inadequate corrosion protection for
reinforcing steel
Insufficient grout cover compromises the bond between grout and
reinforcing steel while also reducing protection against corrosion, moisture
intrusion, and fire exposure. Proper grout coverage is critical to achieving
the intended structural performance of reinforced masonry walls,
especially in seismic regions such as California.
2. In the design of loadbearing masonry walls for a three-story
educational facility, the engineer specifies fully grouted reinforced
masonry because of anticipated lateral wind and seismic forces. Which
statement best describes the primary structural advantage of fully
grouted reinforced masonry over partially grouted masonry systems?
A. Fully grouted walls eliminate the need for control joints in all applications
B. Fully grouted walls provide improved composite action and enhanced
lateral resistance
,C. Fully grouted walls require less reinforcement than partially grouted walls
under seismic loading
D. Fully grouted walls prevent all moisture migration through masonry
surfaces
B. Fully grouted walls provide improved composite action and enhanced
lateral resistance
Fully grouted reinforced masonry improves structural continuity and
increases the wall’s ability to resist shear, bending, and seismic forces. The
grout creates a stronger composite interaction between masonry units and
reinforcing steel, resulting in greater structural integrity.
3. A structural inspector reviewing masonry construction drawings for a
California hospital project notes that seismic detailing requires
horizontal joint reinforcement at specified vertical intervals. What is
the primary purpose of horizontal joint reinforcement in structural
masonry walls?
A. To increase thermal insulation values within masonry cavities
B. To provide resistance against shrinkage cracking and improve wall
integrity
C. To eliminate the need for vertical reinforcing bars in reinforced masonry
D. To prevent mortar discoloration caused by environmental exposure
, B. To provide resistance against shrinkage cracking and improve wall
integrity
Horizontal joint reinforcement helps control cracking caused by shrinkage,
temperature changes, and minor movement while also improving
structural continuity and resistance to lateral forces. In seismic
applications, it contributes to overall wall ductility and integrity.
4. During the evaluation of an existing unreinforced masonry structure
following an earthquake in California, engineers determine that out-
of-plane wall failure occurred because anchorage between the wall
and diaphragm was inadequate. Which structural deficiency most
commonly contributes to out-of-plane masonry wall collapse during
seismic events?
A. Excessive mortar compressive strength
B. Lack of adequate wall-to-diaphragm anchorage
C. Oversized masonry control joints
D. Excessive grout consolidation pressure
B. Lack of adequate wall-to-diaphragm anchorage
Out-of-plane wall failures during earthquakes commonly result from
insufficient anchorage between masonry walls and floor or roof
diaphragms. Proper anchorage transfers seismic forces and stabilizes walls
against overturning and separation.
