**MEASUREMENT DATA, 19831988**

Figure B1 contains sway bolt data

for the building level only. At the time

readings were taken, work was not

complete on the 1983 lift operation.

Stress factors for other levels are ex-

trapolations from the building level

stresses.

Figure B2 contains the second com-

plete set of combined stress factors

since the move in 1982.

Figure B3 contains the second com-

plete set of combined stress factors

since the move in 1982.

Figure B4 contains the third com-

plete set of combined stress factors

since the move in 1982. It is interesting

to compare stress factors for 1984

through 1986 for trends. High stress

concentration factors in general, and

especially at column A4 (>1.60), led to

a recommendation that work be con-

tracted for the next summer to allevi-

ate some of the high stresses. Column

tilts were also a factor in this decision.

Figure B5 contains the fourth com-

plete set of combined stress factors

since the move in 1982 and the first

since the mini-life-extension of 1987.

Comparing stress factors for 1984

through 1987 points up several trends

that are more obvious when examin-

ing Figure 12. Although the mini-life-

extension served to lower most stress

and redistribute stresses among the

columns in general, trends dictated a

repeat of the work performed in 1987

to assure the structural integrity of the

building. Another mini-life-extension

was therefore recommended for 1988.

Figure B6 contains the final com-

plete set of combined stress factors cal-

culated for DYE-2 and the second

since the mini-life-extension of 1987.

Comparing stress factors for 1984

through 1988 points up several trends

which are more obvious when examin-

ing Figure 12. Although the mini-life-

extension was recommended for the

summer of 1988, funding difficulties

were encountered and the work was
