| | SUBMITTALS REVIEW:PANEL WIND LOAD CALCULATIONS |
| | PREPARED BY BLANEY ENGINEERING INC. |
| | ACTION: DENIED |
| | |
| | 1) THE DOCUMENT SUBMITTED BLANEY ENGINEERING HAS BEEN |
| | SUBMITTED ON A FEW PROJECTS AND DENIED IN ALL |
| | CASES.SHEET # 6 OF THIS DOCUMENT INDICATES THE SAFE |
| | ALLOWABLE LOADS THAT CAN BE APPLIED TO THIS FASTENER. |
| | SHEET # 4 IS REDUCING THE SAFETY FACTOR OF THE FASTENER |
| | ITSELI. |
| | |
| | 1A)NOTE # 6 FROM THE STEEL STUD MANUFACTURERS |
| | ASSOCIATION PRODUCT TECHNICAL INFORMATION PACKET |
| | INDICATES, APPLIED LOADS MAY BE MULTIPLIED BY 0.75 FOR |
| | WIND LOADING PER AISI A 5.1.3. |
| | 2004 FBC 1605.3.1.1 ALSO REQUIRES THE LOAD REDUCTIONS: |
| | 605.3.1.1 LOAD REDUCTION. |
| | 1. IT IS PERMITTED TO MULTIPLY THE COMBINED EFFECT OF |
| | TWO OR MORE VARIABLE LOADS BY 0.75 AND ADD THE EFFECT |
| | OF DEAD LOAD. THE COMBINED LOAD USED IN DESIGN SHALL |
| | NOT BE LESS THAN THE SUM OF THE EFFECT OF DEAD LOAD AND |
| | ANY OF THE VARIABLE LOADS. |
| | 2. INCREASES IN ALLOWABLE STRESS SPECIFIED IN THE |
| | MATERIALS, SECTIONS OF THIS CODE OR A REFERENCED |
| | STANDARD SHALL NOT BE PERMITTED TO BE USED WITH LOAD |
| | COMBINATIONS OF SECTIONS 1605.3.1. DURATION OF LOAD |
| | INCREASE SHALL BE PERMITTED IN ACCORDANCE WITH CHAPTER |
| | 23. |
| | EXCEPTION: INCREASES IN ALLOWABLE STRESS SHALL BE |
| | PERMITTED IN ACCORDANCE WITH ACI 530/ASCE 5/TMS 402 |
| | PROVIDED THE LOAD REDUCTION OF SECTION 1605.3.1.1 ITEM |
| | 1 SHALL NOT BE APPLIED. |
| | 3. SIMULTANEOUS USE OF BOTH ONE-THIRD INCREASE IN |
| | ALLOWABLE STRESS AND THE 25-PERCENT REDUCTION IN |
| | COMBINED LOADS SHALL NOT BE PERMITTED. |
| | |
| | 1B) BEFORE THE 2004 FBC THE CODE ALLOWED A 1 1/3RD |
| | INCREASE IN FASTENERS. CURRENTLY ALL PRODUCT APPROVALS |
| | BEFORE THE 2004 FBC WENT INTO EFFECT THEY HAVE TO BE |
| | RE-EVALUATED TO THE 2004 FBC OR HAVE A FLORIDA PE |
| | RECALCULATE THE FASTENER STRENGTH. |
| | |
| | 1C) IN REVIEWING COMPARIBLE FASTENERS CLARK AND WESTERN |
| | HAVE VALUES OF 177 LBS FOR SHEAR AND 84 LBS FOR TENSION |
| | # 10 SCREW 33 MILS/ FY (KSI) 33 |
| | DIETRICH VALUES OF 151 LBS FOR SHEAR AND 75 LBS FOR |
| | TENSION # 10 SCREW 33 MILD/ FY (KSI) 33 |
| | |
| | 1D) SSMA SCREW TABLE NOTES# 4, SCREW STRENGTH NEEDS TO |
| | BE VERIFIED BY THE SCREW MANUFACTER. WE HAVE FOUND SOME |
| | OF THE TIMES THE FASTENERS ARE IMPORTS AND TESTING HAS |
| | NOT BEEN COMPLETED |
| | BECAUSE OF INCONSISTEANCEY OF THE YIELD STRENGHT OF THE |
| | METALS OR ALLOYS.PLEASE PROVIDE THE ACTUAL SCREW |
| | MANUFACTURERS VALUES FOR SHEAR AND TENSION. |
| | |
| | 1E) BLANEY ENGINEERING HAS BEEN CONTACTED BY THIS |
| | OFFICE BY SAMANTHA HILL AND IS AWARE THAT THE VALUES OF |
| | THE FASTENERS WILL NEED TO BE THE MANUFACTURERS VALUES, |
| | THAT YOU DO NOT INCREASE BUT DECREASE VALUES BECAUSSE |
| | OF COMBINED LOADING OF VERTICAL LOADS, GRAVIRTY LOADS |
| | AND HORIZONTAL LOADING THAT MAY OCCUR AT THE SAME TIME. |
| | |
| | WALKER ENGINEERINGPAGE 6 OF 31 |
| | |
| | 2) PLEASE PROVIDE WHERE THE VALUES FOUND ON PAGE 6 |
| | SCREW ALLOWABLE PULLOUT WAS DERIVED FROM. THERE IS |
| | ASSUMPTION OR UNKNOWNS THAT DO MAKE A DIFFERENCE ON THE |
| | VALUES PRESENTED OR THAT WERE NOT STATED. |
| | |
| | 2A) THE BASE METAL THICKNESS (GAUGE) THE FIRST UNKNOWN |
| | IS WHAT TYPE OF METAL ARE WE WORKING WITH FOR THE BASE |
| | METAL, STEEL, GALVENIZED STEEL, STAINLESS, ETC AND ON |
| | THE VALUES OF FY/ FU. |
| | |
| | 2B) AS STATED ABOVE IN THE FIRST SECTION THE ALLOWABLE |
| | WORKING STRENGTH OF THE MATEIALS TO BE FATTACHED |
| | TOGETHER AND THE SCREW TO SEE WHAT IS THE WEAKEST VALUE |
| | THAT CAN BE USED, SINCE THIS WILL BE THE FAILURE POINT. |
| | |
| | 3) UNDER THE WALKER ENGINEERING REPORT PAGE 2 THE |
| | DOCUMENT REFERENCES THE 2007 FBC, THIS IS INCORRECT, |
| | SHOULD READ THE 2004 FBC WITH 2007 SUPPLEMENTS. |
| | |
| | 4) WALKER ENGINEERING REPORT PAGE2 ASCE 7-05 IS |
| | REFRENCED THE 2004 FBC CHAPTER 35 ONLY REFRENCES THE |
| | ASCE 7-02 VERSION PLEASE CORRECT. |
