Current through Register 1525, July 5, 2024
The following words and terms shall, for the purposes of
				  this chapter and as used elsewhere in the code, have the meanings shown
				  herein.
DANGEROUS.
Any building or structure or portion
				  thereof that meets any of the conditions described below shall be deemed
				  dangerous:
1. The building or
				structure has collapsed, partially collapsed, moved off its foundation or lacks
				the support of ground necessary to support it.
2. There exists a significant risk of
				collapse, detachment or dislodgment of any portion, member, appurtenance or
				ornamentation of the building or structure under service loads.
EXISTING STRUCTURE.
A structure erected prior
				  to the date of adoption of the appropriate code, or one for which a legal
				  building
permit
has been issued.
PRIMARY FUNCTION.
A
primary
				  function
is a major activity for which the facility is intended. Areas
				  that contain a
primary function
include, but are not limited
				  to, the customer service lobby of a bank, the dining area of a cafeteria, the
				  meeting rooms in a conference center, as well as offices and other work areas
				  in which the activities of the public accommodation or other private entity
				  using the facility are carried out. Mechanical rooms, boiler rooms, supply
				  storage rooms, employee lounges or locker rooms, janitorial closets, entrances,
				  corridors and restrooms are not areas containing a
primary
				  function
.
SUBSTANTIAL STRUCTURAL DAMAGE.
A condition
				  where:
1. In any
story
, the vertical elements of the lateral force-resisting
				system have suffered damage such that the lateral load-carrying capacity of the
				structure in any horizontal direction has been reduced by more than 20 percent
				from its pre-damage condition; or
2. The capacity of any vertical gravity
				load-carrying component, or any group of such components, that supports more
				than 30 percent of the total area of the structure's floor(s) and roof(s) has
				been reduced more than 20 percent from its pre-damage condition and the
				remaining capacity of such affected elements, with respect to all dead and live
				loads, is less than 75 percent of that required by this code for new buildings
				of similar structure, purpose and location.
TECHNICALLY INFEASIBLE.
An
alteration
of a building or a facility that has little
				  likelihood of being accomplished because the existing structural conditions
				  require the removal or
alteration
of a load-bearing member
				  that is an essential part of the structural frame, or because other existing
				  physical or site constraints prohibit modification or addition of elements,
				  spaces or features which are in full and strict compliance with the minimum
				  requirements for new construction and which are necessary to provide
				  accessibility.

Current through Register 1525, July 5, 2024
Any existing gravity load-carrying structural element for
				  which an
addition
and its related alterations cause an
				  increase in design gravity load of more than 5 percent shall be strengthened,
				  supplemented, replaced or otherwise altered as needed to carry the increased
				  gravity load required by this code for new structures. Any existing gravity
				  load-carrying structural element whose gravity load-carrying capacity is

				  of Section 3403.4.
3403.3.1
Design live load.
Where the
addition
does not result in
				increased design live load, existing gravity load-carrying structural elements
				shall be permitted to be evaluated and designed for live loads

. If the
approved
live load is less than that required by Section 1607,
