 ***THE COMMENT RESPONSE SUBMITTED ON 8/14/12 BY STEVE
 MORAGA, P.E., IS ACKNOWLEDGED. PLEASE RESPOND TO THE
 FOLLOWING COMMENTS WHICH FOLLOW THE SAME NUMBERING
 SEQUENCE AS THE PLAN REVIEW ON 8/1/12:
  
 1) FBC 2002.4 LOADS.
 THE SUBMITTED CALCULATIONS FROM SUNCOAST ARCHITECTURE &
 ENGINEERING:
 (B) THE UNITS OF MEASURE HAVE NOW BEEN CLARIFIED. THE
 VALUES FOR "ALLOWABLE STRESS DUE TO BENDING" AND
 "ALLOWABLE STRESS DUE TO COMPRESSION" STATED ON PAGES 1
 AND 2 OF THE "ENGINEERING CALCULATIONS" APPEAR TOO HIGH
 FOR 6061T6 ALUMINUM. PLEASE STATE THE SOURCE OF THE
 STATED ALLOWABLE STRESS VALUES.
 (E) THE COMMENT RESPONSE LETTER STATES THAT THE MOMENT
 DISTRIBUTION CALCULATION HAS BEEN SUBMITTED TO SHOW
 THAT USING THE SUM OF THE MOMENTS ON EACH BEAM SEGEMENT
 IS A CONSERVATIVE APPROACH. THE LATTER IS NOT A TYPICAL
 METHOD OF ANALYSIS, SO THE MOMENT DISTRIBUTION
 CALCULATION IS VERY RELEVANT. THE DIAGRAMS ON PAGE 3
 AND 7 OF THE "MOMENT DISTRIBUTION CALCULATION"
 CORRECTLY SHOW THAT JOINT 1 IS THE CONNECTION TO THE
 HOST STRUCTURE. THAT CONNECTION IS SHOWN IN DETAIL
 G/A-3 OF THE PROJECT PLANS A PINNED CONNECTION WHICH IS
 TYPICAL. AS SUCH THE CONNECTION DOES NOT AND SHOULD NOT
 TRANSFER MOMENT TO THE HOST STRUCTURE. THAT IS A FACT
 THAT IS NOT RECOGNIZED OR CORRECTLY MODELLED IN MOMENT
 DISTRIBUTION CHART ON PAGE 5 OF THE CALCULATIONS, WHICH
 CLAIMS A 717 FT # (OR 8.6 KP IN.) MOMENT AT THAT
 CONNECTION. THE MOMENT AT THAT PINNED CONNECTION SHOULD
 BE ZERO WHICH MEANS THAT THE STATED 753 FT # MOMENT AT
 THE OTHER END OF THAT SECTION OF THE BEAM IS
 SIGNIFICANTLY UNDERESTIMATED WHICH IN TURN MEANS THAT
 THE SPAN MOMENTS ON THE BEAM ARE ALSO SIGNIFICANTLY
 UNDERESTIMATED. THEREFORE MOMENT DISTRIBUTION
 CALCULATION AS IT STANDS DOES NOT CLEARLY SHOW THAT
 USING THE SUM OF THE MOMENTS ON EACH BEAM SEGEMENT IS A
 CONSERVATIVE APPROACH. PLEASE ADDRESS THIS.

 ***PLEASE ADDRESS THE COMMENTS FROM THE 7/25/12 REVIEW
 BY SAMANTHA HILL. SPECIFICALLY TO ADDRESS THE COMMENT
 REGARDING THE STRUCTURAL ANALYSIS OF THE PRIMARY BEAM
 MEMBERS PLEASE ALSO RESPOND TO THE FOLLOWING:
  
 1) FBC 2002.4 LOADS.
 THE SUBMITTED CALCULATIONS FROM SUNCOAST ARCHITECTURE &
 ENGINEERING:
 (A) THE WIND PRESSURES UNDER "WIND ZONE CORRECTED FOR
 ASD & 18/14 SCREEN" ARE SHOWN AS BEING EXPRESSED IN
 PSI, SHOULD THAT BE PSF?
 (B) THE CALCULATIONS DO NOT STATE WHAT THE UNITS OF
 MEASURE ARE USED TO EXPRESS THE BENDING MOMENT IN THE
 BEAMS. FOR EXAMPLE, FOR THE "CENTER MANSARD SPAN", THE
 "MOMENT DUE TO VERTICAL PRESSURE" IS STATED AS 10,091.
 IS THAT MOMENT OF 10,091 BEING EXPRESSED IN FT-LBS OR
 KIPS?
 (C) WHAT ARE THE VALUES USED IN THE EQUATION W L ^2 /
 12 THAT GIVE THE MOMENT OF 10.091?
 (D) THE "TOTAL OF ALL MANSARD MOMENTS" SEEMS TO HAVE
 BEEN CALCULATED BY SUMMING THE MOMENTS ON THE "WINDWARD
 MANSARD LEG", THE "CENTER MANSARD SPAN", AND THE
 "LEEWARD MANSARD LEG". THE "MOMENT DUE TO HORIZONTAL
 LEEWARD PRESSURE" ON THE "LEEWARD MANSARD LEG" HAS BEEN
 SUBTRACTED FROM THE OTHER MOMENTS. BECAUSE IT HAS BEEN
 SUBTRACTED, THIS IS MUST HAVE BEEN CONSIDERED A
 "NEGATIVE" BENDING MOMENT. HOWEVER THE MAXIMUM VALUE OF
 THAT NEGATIVE MOMENT DOES NOT OCCUR AT THE SAME SECTION
 OF THE BEAM AS ANY OF THE OTHER MOMENTS. IN FACT THE
 FIVE BENDING MOMENTS, THAT HAVE BEEN SUMMED IN ORDER TO
 ARRIVE AT THE "TOTAL OF ALL MANSARD MOMENTS" ,WILL
 OCCUR AT FIVE DIFFERENT PLACES ALONG THE BEAM. PLEASE
 EXPLAIN THE APPROACH USED TO DETERMINE THE MAXIMUM
 MOMENT. THIIS REQUEST IS ALSO RELATED TO (E) BELOW.
 (E) THERE IS NO POST OR OTHER ELEMENT PROVIDING
 VERTICAL SUPPORT TO THE TOP OF THE MANSARD, YET WHEN
 CALCULATING THE MOOMENT DUE TO VERTICAL PRESSURE THE
 BEAM SPAN HAS NOT BEEN TAKEN AS 29 FEET 7 INCHES WHICH
 IS THE DISTANCE BETWEEN THE POST AND THE STRUCTURAL
 GUTTER ON THE HOUSE. THE ADOPTED APPRAOCH IS NOT A
 TYPICAL METHOD OF ANALYZING THE BENDING MOMENT ON THE
 BEAM. PLEASE EXPLAIN THE APPROACH USED. THIS COMMENT IS
 ALSO RELATED TO (D) ABOVE.
 (F) LOOKING AT THE "COMPRESSION IN THE MANSARD BEAM",
 WHAT ARE THE VALUES USED IN THE EQUATION (WALL AREA X
 HORIZONTAL PRESSURE)/2 THAT GIVE A COMPRESSION OF 1,057
 LBS?
 (G) THE MANSARD BEAM DEFLECTION IS STATED AS 0.05. THIS
 MUST BE ASSUMED TO BE EXPRESSED IN INCHES SINCE IT IS
 BEING COMPARED TO AN "ALLOWABLE DEFLECTION" OF 2.02.
 PLEASE STATE WHAT DEFLECTION EQUATION AND VALUES ARE
 USED TO ARRIVE AT A MANSARD BEAM DEFLECTION OF JUST
 0.05 INCHES.

 FBC RESIDENTIAL 301.1 (RESISTANCE TO WIND):
  
 1. REGARDING BEAM SPAN CALCULATIONS, SHEET 1, PLEASE
 REVISE TO INCLUDE THE VALUE FOR 'L'. THIS APPLIES TO
 CENTER MANSARD SPAN, WINDWARD MANSARD LEG, AND LEEWARD
 MANSARD LEG. CALCULATION IS PROVIDED BUT REFERS TO WL,
 PLEASE PROVIDE SPANS (DIMENSION OF L).
  
 2. BASED ON LAT/LONG LOCATION, THIS PROJECT APPEARS TO
 BE IN THE 152 MPH WIND ZONE (WWW.ATCOUNCIL.ORG). EITHER
 PROVIDE INFORMATION TO SHOW HOW ENGINEER HAS DETERMINED
 WIND SPEED, OR REVISE PLAN TO A MINIMUM OF 152MPH.
  
 IF OTHER COMMENTS ARE ADDRESSED AND PLANS DO NOT NEED
 TO BE REVISED, A LETTER FROM ENGINEER THAT THIS DESIGN
 COMPLIES WITH 152MPH WILL SUFFICE.
  
 3. DUE TO THE DELAY IN FIRST PLAN REVIEW, ENGINEER MAY
 PROVIDE THIS INFORMATION VIA EMAIL FOR PRELIMINARY
 REVIEW TO DETERMINE WHETHER ADDITIONAL INFORMATION IS
 REQUIRED. BEAMS APPEAR OVERSTRESSED.
  
 PLEASE FEEL FREE TO CONTACT ME TO DISCUSS.
