For any other type Of masonry tn
unit stress shall be calculated on thu
basis of a factor Of safety Of 10 Oh
more in accordance with STANDARD
practice.
Section II. Hollow Building Block:
In buildings not more than 40 feet
high, hollow tile or concrete blocks
NAV be used for outside walls and M
side bearing walls, as well as for nom
bearing partitions. Such blocks Tex
cept FOR non-bearing partitions)
shall have an ultimate compressive
strength of not less than TOO pounds
per so. in. Of gross area. In compu-
ting the gross area, no deduction shall
be made for hollow spaces.
The hollow spaces shall not exceed
I SIS per cent in the case Of terra Gotta
or clay tile, or 33 per cent in the case
of concrete blocks; except that IN
CLAY tile used in one-story buildings
the follow spaces shall not exceed gu
per cent. The absorption shall not
exceed IL per cent in AZ hours.
Such walls shall be laid in Portland
cement moran. The thickness OF
such walls shall be the same as re-
ouired for brick walls, but no such
wall shall be higher than Is times its
thickness.
Brick facing may be considered as
part of hollow tile or concrete block
wall Tor vice versa) if the two mat
erials are properly bonded with head
err courses of brick not farther apart
than every sixth course.
Reinforced Concrete Construction.
Section 1S. Definition. The term
reinforced concrete" in this ordin-
ance shall mean an approved concrete
n,;xture in which steel is embedded In
such a manner as to resist all tensile
stresses and to add rigidity and
strength to concrete in compression
Reinforced concrete Will be approx
ed for all types OF building construe-
ton, provided the design CONFORMS
with good engineering practice, as SET
forth in the report of the JOINT Com,
mite on Concrete and Reinforced
Concrete as published by the Amerl-
can Society for Testing Materials
The construction shall meet the re,
ouirements of this Ordinance IN all
respects. p.,.I
Plans and Specifications to be flied.
The plans and specifications to be
filed with the Chief Building lnspec-
tor shall be accompanied by stress
and descriptions show
ing the general arrangement OF the
entire construction in all important
details, including the size, length, ana
noints of bending of all reinforcement,
the Qualities, proportions, and me,
thods of mixing the materials used
in the concrete and the dead and nVe
loads each floor is designed to carry.
All such plans and specifications
shall be signed by the Architect, En-
pineer, Contractor or person applying
for the permit. In no case shall the
CONSTRUCTION deviate from the approx
ed plans and specifications except by
written consent OF the Chief Building
Inspector.
Concrete for reinforced concrete
shall consist Of medium
wet mixture of one part of Portland
cement to not more than six parts OF
a aggregate, fine and coarse, In sucn
nronortions as to produce the great !
est density.
Inspection. Every reinforced con-
crete building shall be erected UNDER 1
the constant supervision OF reputa-
bile and competent inspector, furnish
ed by the Owner, Architect, or Engin-
Ger. and acceptable to the Chlef I
Building Inspector. :,
Section 10. Quality of Structural
Timber. All timbers and wooden
beams used in building shall be OF !
good. sound material, free from rot,
|arge and loose knots, shakes or any
mperfections whereby the strength |
NAV be impaired and of such size
and dimensions as to the purposes
for which such building is intended
require.
Size of Timbers.
Whenever the size of timber is
yiven in whole numbers such as 2x4,
,x6. 2x8, etc. standard commercial or
.c,sin.l .i.as dva meant hut when
.ver the size is given as l So 8 5-S,
5-sx5 SO, / SO K tn, etc., actual
lies are meant. The allowable
stresses permitted by this Ordinance
ire to be based on the actual size OF
he timbers used.
For timber four (4) inches by four
a inches land larger, the size may
,e one-half GU Of an inch less for
ZACH dimension. -,
Section 20. Roof Coverings. All
buildings may be covered with such
material as brick, con-
rete, tile or slate; or with tin, or
,alvanized iron with standing seam or
an Joints; or with not less than 3
,ly built up roofing of felt, with pitch
nd gravel or Stag surfaces or with
,uilt up asbesto roofing: or with ,
ther incombustible roofing approved
