otherwise unloaded floor would produce stresses greater than those caused by a uniformly distributed
load of 250 kilograms per square meter (50 punds per square foot).
(c) In designing floors to be used for industrial or commercial purposes, the actural live load cuased
by the use to which the building or part of the building is to be put shall be used in the design of such
building or part thereof, and special provision shall be made for machine or apparatus loads when such
machine or apparatus would cause a greater load than specified for such use in Section 1.04.
(d) Floors in office buildings and in other buildings, where partition locations are subject to change,
shall be designed to support in addition to all other loads, a uniformly distributed load equal to 100
kilograms per sqaure meter (20 punds per square foot).
Public garages and commercial or industrial buildings in which loaded trucks are placed,
used or stored shall have the floor systems designed to support a concentrated rear whhel load of a
loaded truck placed in any possible position.
Garages for the storage of private pleasure cars shall ahve the floor system designed for a
concentrated wheel load of not less than 900 kilograms (2000 pounds).
(g) Critical distribution of Live Loads. Where structural members are arranged so as to create
continuity, the loading conditions which would cause maximum shear and bending moments along the
member shall be investigated. Where uniform floor loads are involved, consideration may be limited to
full dead load on all spans in combination with full live load on adjacent spans and on alternate spans.
(h) Where uniform roof loads are involved consideration may be limited to full dead load on all
spans in combination with full live load on all spans and on alternate spans.
Section 1.03 Method of Design (a) Any system or method of construction to be used shall admit of a rational analysis in accordance
with well-established principles of mechanics.
(b) All allowable stresses and soil-bearing values specified in this Code for working stress design
may be increased one-third when considering wind or earthquake forces either acting alone or when
combines with vertical loads. No increase will be allowed for vertical loads acting alone.
(c) Load factors for ultimate strength design of concrete and plastic design of steel shall be as
indicated in the appropriate Chapters on the materials.
(d) Wind and earthquake loads need not be assumed to act simultaneously. Section 1.04 Unit Live Loads (a) The unit loads set forth in Tables No. 1.04-A, 1.04-B, 1.04-C 7 1.05-A shall be taken as the
minimum live loads per unit area of horizontal projection to be used in the design of buildings for the
occupancies listed, and loads at least equal shall be assumed for uses not listed in this Section but which
create or accommodate similar loadings.
(A) FLOOR LOADS.
