1 Discussed Questions Submitted to T
'a'e i s s V, E GAI provided drawings showing location of heavy equipment and tna r weights (note, this weight was previously included in unifor= load pmvided earlier which also included exterior wall weights).
Clarified uniform floor loadings.
Showed fabrication dr;svings for typical connections in turbine, 3
auxiliary and intermediate buildings. Beans are connected ty web
.,8 p
i angles to the columns in a shear connection.
Bracir.g members are
- .y attached to gusset plates primarily by bolts. Where the bracing crosses, the angles ars cut and there are four connections to a
]
center plate.
In many cases the web angles were attached to the
%s beasa by welding then bolted to the coliaans in the field.
.t A
2 The providing of details for specific connections nas deferred until
'L9
+
LLL's analysis was complete and critical areas identified.
At that time, details on the connections in the critical areas would be W
reque sted. This was also the decision on the question of aseber Z
(
forces due to dead load.
- p It was decided that LLL had sufficient information to model the 1
diesel generator building and control building. A set of plans were l
provided at the seeting.
l l
The concrete block walls in the intermediate building are sitting cm
.q l
girders and are olipped to the columns on 24' c/c. They are unreinforced and do not provide lateral stiffness. Their mass should
(
probably be included.
.g i
b."
i 7
It was felt that shear studs on girders were confined to semil local
[
j areas.
However, upon checking drawing fD-502-022, a note was found which states that "All girders and beams connecting to columns... to
'g aj have 3/4" o.d. welded studs..."
in the turbine building.

Also, the centrol roos Nuipment is located on f'oces suppcrted by
(
steel framing. These ites:s will seat likely experience amplified j
vertical excitation.
Thus, vertical spectra should te gunerated for t hem.

The chords for the horisontal trusses fl, T2, and 73 are attached to the east facade wall coltans with four bolts through both flanges.
A field check was going to be conducted by RG&E to determine if any

The Gilbert model also includes all contributing beams and columns of g
the turbine, auxiliary, and intermediate buildings.

(
Includes a rough model of thei' service' building with rigid diaphragas connected to the ausilisry building diaphrases with a ocupied spring l
(in the form of a stiffness matrix).

Floors are rigid diaphrsgas eacept intermediate building whica is
?,
modeled with equivalent benas jros mass point at the o.G. to the fruming connections. The floor, diaphragas have six degrees of freedom.
r j
In g1neral, the asases of the floors were moved in elevation to k
eerrespond to those of braos points.
.?
i I
The connection of the floor members to columne is eensidered fixed due to the concrete placement around the coltans.

Eineestic condensation will be used (in STARDTIE) to reduce the gy k
number of (dynamic) degroes of freedom.

Model of internal structure (inside containment) is for piping input, not for l
analysing structurst integrity or equipment. They are trying to be conservative, perhaps too conservative for non-piping considerations. The l
equivalent sesber properties are still useful for our analyses. nerefore, we i
would like a copy of their model.
