LOCATION AND DESCRIPTION OF VIBRATION DATA
imbient vertical and horizontal (west) floor vibrations were
recorded in loom 114427-N. These data are documented as Record 1. The
top trace represents vertical motion and the bottom horizontal motion
near the center of the bay bounded by Column Lines 7 and 8 and Column
Linos G and H.
LOCATION 5
Ambient vibratory motions of the foundation block located in
the room (first floor) were recorded at various positions on the
foun a ion co evaluate vertical, translational and rocking motion. Data
were also recorded on the foundation and the adjacent floor to evaluate
the ambient motion of the foundation with respect to the floor. These
data are documented as Records 2 through 9. A desc.iption of each record
is as follows:
Record 2 - Vertical vibratory motion of the northeast (top
trace) and northwest (bottom trace) corners of the foundation.
Record 3 - Vertical vibratory motion of the northeast (top
trace) corners of the foundation.
Record 4 - Vertical motion of the northeast (top trace) and
southeast (bottom trace) corners of the foundation.
Records 5 and 6 - Vibratory motion of the foundation block and
the adjacent floor were recorded at the northeast corner of
the foundation. The top trace represents the vertical move- .
ment of the foundation and the botzom trace the vaetical move-
ment of the floor. Record 6 is a repeat of Record 5 with the
velocity transducers interchanged to ch4......k that they are func-
tioning properly.
Record 6a - Same as Rec )rd 6.
Record? - Horizontal vibrations in the ncrth (top trace) and
east (bottom trace) directions were recorded at the centerline
of the north end of the foundation block.
Record 8 - Horizontal vibrations of the foundation block and
the floor were measured and recorded. The top trace is a
record of vibratory motion of the foundation block in an
easterly direction measured at the center of the north end
of the block. The floor horizontal motion (bottom trace) in
no easterly dl rection WaH meashred at the northeast corner of
