c. Vertical resisting elements data. The information to be entered in this part of the form is
also intended to be primarily a brief description of the structural element, but it should also provide
some indication as to distribution of the element. (For example, "Reinforced concrete shear walls in
longitudinal and transverse directions in the interior of the building," or "Steel braced frames at
building perimeter in longitudinal and transverse directions.") Some buildings may have a different
system in each of the orthogonal directions (e.g., moment-resisting frames in the transverse
direction, and braced frames or shear walls in the longitudinal direction). The notation "braced or
trussed columns" refers to the use of knee braces or trusses to resist lateral-load moments by
"fixing" or restraining one or both ends of a column. For infilled frames, it is important to note the
type of frame (e.g., structural steel or reinforced concrete) and the type of infill (e.g., unreinforced
masonry, reinforced concrete, or hollow clay tile).
d. Site soil profile classification. The applicable soil profile should be noted as one of the six
standard site classes described in Table B-2. The identification will be obtained from a site
geotechnical report, if available. If a geotechnical report is not available, the reviewer will select a
site class based on his review of the soil borings, geologic maps, or other data, and should note the
basis of his selection in the space provided on the form.
e. Foundations. The person performing the review should note the basic foundation system
features, design, and detailing in the space provided, including the following items:
(1) For wood frame buildings, are the mud plates for the stud walls bolted to the foundation
walls or strip footings? Are tension hold-downs provided for slender piers acting as shear walls?
(2) For reinforced concrete frame buildings, are the footings capable of resisting the lateral
load moments? If the column vertical reinforcement is spliced at the top of the footing, is the splice
capable of developing the tension strength of the bars? If the footing is deeply embedded below
grade, is the footing capable of resisting negative moment? (e.g., is there a layer of reinforcement at
the top of the footing as well as the bottom?)
(3) For piles or caissons, is the vertical reinforcement adequately anchored into the cap
footing to resist lateral load moments? In soft soils, are the pile or caisson cap footings adequately
connected with tie beams to preclude lateral displacements?
