Article 2 - DEAD LOADS

Section 27-553

Section 27-553

  §   27-553   Construction   materials   and   assembled   elements  of
construction.  Except as provided in section 27-555 of this article, the
dead load shall be the  actual  weight  of  the  building  materials  or
construction  assemblies to be supported, computed from the unit weights
given  in  reference  standard  RS  9-1.  Where  unit  weights  are  not
established  in  reference  standard  RS  9-1, the actual weights may be
determined by analysis  or  from  data  in  manufacturers'  drawings  or
catalogs.  Unit  weights  less than those given in reference standard RS
9-1 may be used only with approval of the commissioner.

Section 27-554

Section 27-554

  § 27-554 Service equipment. Provision shall be made for the weights of
all  building  service  equipment  including  plumbing  stacks,  piping,
heating and air conditioning equipment, electrical equipment, elevators,
elevator machinery, flues, and similar fixed equipment. The  weights  of
such  equipment  (or  the  allowances therefor) shall be included in the
dead load. The weight of equipment that is part of the  occupancy  of  a
given  area  shall be considered as live load. See also paragraph two of
subdivision (b) and subdivision (d) of section 27-557 of  article  three
of this subchapter.

Section 27-555

Section 27-555

  §   27-555  Partition  loads.  Weights  of  all  partitions  shall  be
considered, using either actual weights at locations shown on the  plans
or the equivalent uniform load given in subdivision (b) of this section.
  (a) Actual loads. Where actual partition weights are used, the uniform
design  live load may be omitted from the strip of floor area under each
partition.
  (b) Equivalent uniform load. The equivalent uniform partition loads in
reference standard RS 9-1 may  be  used  in  lieu  of  actual  partition
weights except for bearing partitions or partitions in toilet room areas
(other  than in one- and two-family dwellings), at stairs and elevators,
and similar areas where partitions  are  concentrated.  In  such  cases,
actual  partition  weights  shall be used in design. Except as otherwise
exempted,  equivalent  uniform  loads  shall  be  used  in  areas  where
partitions  are  not  definitely located on the plans, or in areas where
partitions are subject to rearrangement or location.
