3-7.2.3 Some Tenants have concentrated loads in the form of banks of files or safes;
the designer should inquire as to whether there are special loads which need to be
accommodated in the design.
3-7.3
Lateral Design
3-7.3.1 Seismic lateral loads are determined according to \ the latest DoD guidance
set forth in UFC 1-200-01 "General Building Requirement"/2/. A geotechnical engineer
should determine the seismic Site Classification during the site evaluation and prior to
the project feasibility study.
3-7.3.2 Wind lateral loads are determined according to \ the latest DoD guidance
set forth in UFC 1-200-01 "General Building Requirement" /2/. Basic wind speeds are
also found in UFC 3-310-01 "Design: Structural Load Data". \ However, in the event
of discrepancies, the former shal govern./2/ An Importance Factor of 1.0 should be
applied to the design of training centers.
3-7.3.3 Wind pressures (components and cladding) on roof systems should be shown
on construction documents. Structural should determine cladding wind pressure values
and information could be shown on architectural roof plans.
3-7.3.4 Provide redundant lateral resisting systems to comply with AT/FP
requirements. Refer to Section 3-7.6 for further information.
3-7.4
Structural Ceiling Grid System: Below the sloped roof, provide a U-shaped
cold-formed channel grid system for ceiling, mechanical/electrical equipment support
and lateral support of nonload-bearing partition walls. Grid system should be laterally
braced for site-specific seismic conditions. Minimum lateral design load will be 0.25 kPa
(5 psf) applied to supported elements.
