RE: Plan Check: BLD2014-1165
Project: Heslop Remodel/Addition
Project Address: 652 3rd Avenue N.
Response to City Comments
12. Sheet 12
a. Wall TF was omitted from the analysis. Please revise the calculations to show wall TF.
Response: Please see revised analysis showing wall TF.
b. The calculations at wall TA do not match the plans. Please reconcile the calculations
to match the plans.
Response:The length of solid wall TA is 4.3 ft as indicated in the analysis. The rest
of the shearwall contains some openings.
c. The overturning force shown at wall TA exceeds the tabulated capacity for
STHD10/10RJ holdowns in the Simpson catalogue. Please select a holdown with
adequate capacity.
Response:The holdown has been revised to STHD14RJ with ultimate capacity of
5912 lbs. The Simpson table shows service level tension capacity. They need to be
multiplied with 1.4 for seismic load and 1.6 for wind load to obtain ultimate
capacity. Please see attached note from Simpson table and ultimate capacity of
holdowns. The shearwall analysis has been done in ultimate loads per ASCE 7-10.
d. The overturning force shown at wall TE exceeds the tabulated capacity for I-IDU5
holdowns in the Simpson catalogue. Please select a holdown with adequate capacity.
Response: The holdown has been revised to H 4 with ultimate capacity of 7304
lbs. The Simpson table shows allowable/service level tension capacity. They need
to be converted to ultimate capacity using a factor of 1.4 for seismic and 1.6 for
wind load. Please see attached note from Simpson table and ultimate capacity table
of holdowns.
e. Please justify the use of a 1.15 live load reduction in analyzing the floor beams.
Response: Some of the beams are supporting both floor live load and roof snow
load at the same time. Per code, we are allowed to use the shortest load duration
factor (Cd) . In this case, the snow load has Cd= 1.15 while live load Cd= 1.0
f. It appears the no live load was applied to beam 1324. Please revise.
Response: Wall loading has been applied to the beam. It includes wall dead load,
roof dead load and snow load.
g.Beam B2-3Acould not belocated onthe plans. Please advise.
Response: Please ignore this beam calculations since it is not pad of the framing plan.
Sheet S-1
To avoid confusion in reading the unCVDwaDUOn8| layout (typically, the roof framing plan is
dr@vVD with the upper floor plan, the upper floor framing p|8D with the main floor plan, eiC.),
p|8GSe revise the title of 1/S'1 LV 'Main F|oorP|8n/N1ain Floor Framing.
Response: The title has been revised.
Sheet S-2
Per item #13 ohove, please revise the Ui|e of 1/S'2 to 'Upper Floor Plan/Upper Floor
Framing.
Response: The title has been revised.
Per item #13above, please revise the title of2/S-2to'Roof Framing P|8U'.
Response: The title has been revised.
