Dear John:
Subject: Structural Responses to Plan Review #1
As you requested, the following list is in response to open structural items for the subject project:
Refer to revised elevation on 2/S2.11 with correct detail call -out 13/S4.0.
,2. Refer to revised elevation on 2/S2.11 with correct detail call -outs at correct
locations.
,3 Refer to attached calculation sheets PC -3a through PC -3b. Further clarification
• also on response to plan check item 14.
/4: The added floor framing is located at grade level. The space below the framing is
an existing tunnel. Therefore, wall anchorage is not required and cross -grain
bending will not occur. Refer to revised detail 17/S6.5 for correct floor elevation.
. Refer to revised plan on 2/S2.12. This note was removed.
Refer to revised plan on 1/S2.12 with missing detail numbers provided.
Refer to revised plan on 1/S2.12 with correct detail call -out 8/S3.2.
Refer to attached calculation sheets PC -8a through PC -8h for loads applicable to
composite fiber reinforcing (CFR). CFR is a deferred submittal item; therefore the
product manufacturer will supply specific details. The composite fiber reinforcing
shown on details 3/S2.13, 4/52.13, and 18/S3.1 is being utilized for in -plane
lateral loading to the concrete walls, therefore the CFR is tensile reinforcing for a
- concrete beam and not an uplift force.
,! Refer to attached calculation sheets PC -9a through PC -9c.
At. Refer to revised plan on 1/52.32 and new detail 15/S6.4.
,ra -. Refer to drawing S6.5. Detail 7/S6.5 has been changed to 10/S6.5.
lv �2 ' Refer to attached calculation sheets PC -12a through PC -12c and new detail
4 16/56.5.
..„1- 3 to revised detail 17/S3.1 with correct detail call -out 11/S4.0. Also refer to
revised detail 11/S4.0 with correct column call -out.
)A!Refer to original calculations dated May 3, 2004. See pages LS -98 through
LS -106 for collector calculations using design loads specified in code section
1630.3.1. The typical beam connections shown on detail 5/S1.2 have been
utilized for these loads. Design loads shown in the calculations have been
converted to allowable stress loads. This method is clarified in attached
calculation sheets PC -14a through PC -14c.
r 1,5, Refer to revised detail 18/S3.4. 2 1/2" diameter pipe is specified.
/YS. Refer to revised detail 19/S3.4. 7/8" diameter A325x bolts are specified.
/r7. Refer to new detail 17/S3.5.

.28'! Refer to revised plan 1/S3.5 with corrected detail call -out 16/S3.5.
/2T. Refer to revised detail 14/S3.5. The L6x3 1/2x5/16 is not a structural member as
it only serves only as closure piece for the composite deck that bears on the steel
tubes at each end.
Refer to revised detail 18/S3.5. The correct member size is noted as
HSS10x6x3 /8. Also refer to calculation sheet PC -22.
Refer to revised detail 20/S3.5. Detail 6/53.5 is noted.
}4''Refer to revised detail 20/S3.5. HSS 6x4x1/4 is noted.

Refer to revised detail 11/S6.3.
--40 Refer to revised detail 18/S6.3.
p 4.1! Refer to original calculations dated May 3, 2004. The calculations on sheet BD -2
check single plate shear connections for HSS columns based on AISC procedure
defined in pages 4 -96 through 4 -108 of "Hollow Structural Sections Connections
Manual ". As defined by this procedure, the support is considered rigid since the
reaction eccentricity is located within the bolted connection. For calculation of
lateral connection refer to attached calculation sheet PC -41.
Refer to revised detail 17/S6.5.
...4 Refer to revised detail 10/56.6.
___44-. to revised detail 15/S6.6.
Refer to original calculations dated May 3, 2004. Calculation on sheet BD -4
includes an un- shored stress check under the summary section.
