EARTHQUAKE HAZARD REDUCTION IN
EXISTING UNREINFORCED MASONRY WALL BUILDINGS
Section 17.34.010. The purpose of this chapter is to promote public safety and
welfare by reducing the risk of death or injury that may result from the effects of
earthquakes on unreinforced masonry bearing wall buildings.
The provisions of this chapter are intended as minimum standards for structural seismic
resistance established primarily to reduce the risk of life loss or injury. Compliance with
these standards will not necessarily prevent loss of life or injury or prevent earthquake
damage to rehabilitated buildings. Building owners who retrofit their buildings in
Petaluma in accordance with the provisions of this chapter shall be deemed to have used an
acceptable standard of care to protect the safety of the public and occupants of the
building. This chapter does not require alteration of existing electrical, accessibility,
plumbing, mechanical or fire safety systems.
ApplicabilitX

IN-PLACE MASONRY SHEAR TESTS
The bed joints of the outer wythe of the masonry shall be tested in shear by laterally
displacing a single brick relative to the adjacent bricks in the same wythe. The head joint
opposite the loaded end of the test brick shall be carefully excavated and cleared. The
brick adjacent to the loaded end of the test brick shall be carefully removed by sawing or
drilling and excavating to provide space for a hydraulic ram and steel loading blocks. Steel
blocks, the size of the end of the brick, shall be used on each end of the ram to distribute
the load to the brick. The blocks shall not contact the mortar joints. The load shall be
applied horizontally, in the plane of the wythe, until either a crack can be seen or slip
occurs. The strength of the mortar shall be calculated by dividing the load at the first crack
or movement of the test brick by the nominal gross area of the sum of the two bed joints.
UNIFORM BUILDING CODE STANDARD N0.24-42
POINTING OF UNREINFORCED MASONRY WALLS
POINTING
The old mortar should be cut out, by means of a toothing chisel or a special painter's
grinder, to a uniform depth of 3/4", or until sound mortar is reached. Care must be taken
not to damage the brick edges. All dust anal debris must be removed from the joint by
brushing, blowing air or rinsing with water.
Mortar mix shall be Type "S" or "N" proportions as called for in the construction
specification. The tuck-pointing mortar should be pre-hydrated to reduce excessive
shrinkage. The proper pre-hydration process is as follows:
All dry ingredients should be thoroughly mixed. Only enough clean water should be
added to the dry mix to produce a damp, workable consistency which will retain its shape
when formed into a ball. The mortar should stand in this dampened condition for one to
one and one-half hours.
The joints to be tuck-pointed should be dampened, but to ensure a good bond, the
brickwork must absorb all surface water. Add water to the pre-hydrated mortar to bring it
to a workable consistency which is somewhat drier than conventional mortar. The mortar
should be packed tightly into the joints in thin layers not to exceed 1/4 inch. Each layer
should become "thumbprint hard" before applying the next layer. The joints should be
tooled to match the original profile after the last layer of mortar is "thumbprint hard".
RELAYING OF BRICK
Replacement bricks must match the originals with respect to size, color, and texture where
exposed. Atuck-pointing tooling chisel should be used to cut out of the mortar which
surrounds the affected units. Power driven impact tools are not allowed. Once the units
are removed, all of the old mortar shall be carefully chiseled out and all dust and debris
shall be swept out with a brush.
If used brick is to be relayed, it shall be cleaned of all old mortar. The brick surfaces in the
wall shall be dampened before new units are placed, but the masonry should absorb all
surface moisture to ensure a good bond. The appropriate surfaces of the surrounding
brickwork and the replacement brick should be buttered with mortar. The replacement
brick should be centered in the opening and pressed into position. The excess mortar
12
o~.~ -g~ a ~-~
should be removed with a trowel. Pointing around the replacement brick will help to
ensure full head and bed joints. When the mortar becomes "thumbprint hard", the points
shall be tooled to match the original profile.
