Unified Facilities Criteria (UFC)
Revision Summary Sheet
Subject: UFC 3-310-01, Design: Structural Load Data
Cancels: UFC 3-310-01, Load Assumptions for Buildings, dated 30 June 2000
Description of Change: This update to UFC 3-310-01 compiles and updates the structural
loading data to be used in the design of buildings and other structures. The International
Building Code (IBC) has been adopted as the buildings code for the Department of Defense, as
modified by UFC 1-200-01. The load data included in UFC 3-310-01 compliments and expands
the usage of the IBC for DoD facilities in the following ways:
The minimum live load table is expanded to include DoD unique occupancies or
functions.
The design wind speed, ground snow loading, frost penetration depth, and seismic
spectral accelerations are identified at specific DoD facilities within the U.S. its
territories and possessions.
The best available design wind speed, ground snow loading, frost penetration depth,
and seismic spectral accelerations are identified at specific DoD facilities outside if
the U.S. its territories and possessions.
The best available design seismic spectral accelerations are provided at additional
locations overseas.
Reasons for Change: The existing guidance was inadequate for the following reasons:
The minimum live load data in the existing UFC 3-310-01 did not mesh well with the
data in the IBC due to differences in terminology and conflicting / out of date
guidance.
The existing lists of DoD locations, both within the United States and overseas, were
incomplete and didn't reflect many locations where installations had been eliminated.
The design wind speed and ground snow loading data in the existing UFC 3-310-01
was out of date and did not agree with the requirements of the IBC.
The design seismic spectral accelerations for specific DoD sites within the U.S. were
not available.
The listing of design seismic spectral accelerations outside of the U.S. was
inadequate, the data was out of date, and inaccurate.
Impact: The following direct benefits will result from the update of UFC 3-310-01:
Creation of a single source reference for structural loading requirements that provide
clear and consistent guidance for the design of DoD facilities.
o Eliminates interpretation and ambiguity that could lead to design and
construction conflicts.
o Facilitates update and revision as better information becomes available.
Creation of up to date load data that compliments the IBC and allows the use of a
common minimum structural safety standards for all DoD facilities.
(The evaluation / update of the design seismic spectral accelerations at overseas sites
ensures that structures are designed to the appropriate level. Revision of the
seismic design values will typically result in reduced constructions costs since the
previous values were approximations that were often overly conservative.)
