| | CORRECTIONS NEEDED - FBC WPB AMENDMENTS 107 |
| | 1) PLEASE SHOW THE WATER BARRIER TO COMPLY WITH FBC |
| | R703.2 WATER-RESISTIVE BARRIER. |
| | ONE LAYER OF NO. 15 ASPHALT FELT, FREE FROM HOLES AND |
| | BREAKS, COMPLYING WITH ASTM D226 FOR TYPE 1 FELT OR |
| | OTHER APPROVED WATER-RESISTIVE BARRIER SHALL BE APPLIED |
| | OVER STUDS OR SHEATHING OF ALL EXTERIOR WALLS. NO. 15 |
| | ASPHALT FELT SHALL BE APPLIED HORIZONTALLY, WITH THE |
| | UPPER LAYER LAPPED OVER THE LOWER LAYER NOT LESS THAN 2 |
| | INCHES (51 MM). WHERE JOINTS OCCUR, FELT SHALL BE |
| | LAPPED NOT LESS THAN 6 INCHES (152 MM). OTHER APPROVED |
| | MATERIALS SHALL BE INSTALLED IN ACCORDANCE WITH THE |
| | WATER-RESISTIVE BARRIER MANUFACTURER?S INSTALLATION |
| | INSTRUCTIONS. THE NO. 15 ASPHALT FELT OR OTHER APPROVED |
| | WATER-RESISTIVE BARRIER MATERIAL SHALL BE CONTINUOUS TO |
| | THE TOP OF WALLS AND TERMINATED AT PENETRATIONS AND |
| | BUILDING APPENDAGES IN A MANNER TO MEET THE |
| | REQUIREMENTS OF THE EXTERIOR WALL ENVELOPE AS DESCRIBED |
| | IN SECTION R703.1. |
| | 2) SIDING IS SUBJECT TO WIND LOADS. PLEASE SHOW THE |
| | SIDING TYPE AND REQUIRED ATTACHMENT TYPE, SIZE AND |
| | AMOUNT FBC R703.1.2 WIND RESISTANCE. |
| | WALL COVERINGS, BACKING MATERIALS AND THEIR ATTACHMENTS |
| | SHALL BE CAPABLE OF RESISTING WIND LOADS IN ACCORDANCE |
| | WITH TABLES R301.2(2) AND R301.2(3) FOR WALLS USING AN |
| | EFFECTIVE WIND AREA OF 10 SQUARE FEET. WIND-PRESSURE |
| | RESISTANCE OF THE SIDING AND BACKING MATERIALS SHALL BE |
| | DETERMINED BY ASTM E330 OR OTHER APPLICABLE STANDARD |
| | TEST METHODS. WHERE WIND-PRESSURE RESISTANCE IS |
| | DETERMINED BY DESIGN ANALYSIS, DATA FROM APPROVED |
| | DESIGN STANDARDS AND ANALYSIS CONFORMING TO GENERALLY |
| | ACCEPTED ENGINEERING PRACTICE SHALL BE USED TO EVALUATE |
| | THE SIDING AND BACKING MATERIAL AND ITS FASTENING. ALL |
| | APPLICABLE FAILURE MODES INCLUDING BENDING RUPTURE OF |
| | SIDING, FASTENER WITHDRAWAL AND FASTENER HEAD |
| | PULL-THROUGH SHALL BE CONSIDERED IN THE TESTING OR |
| | DESIGN ANALYSIS. WHERE THE WALL COVERING AND THE |
| | BACKING MATERIAL RESIST WIND LOAD AS AN ASSEMBLY, USE |
| | OF THE DESIGN CAPACITY OF THE ASSEMBLY SHALL BE |
| | PERMITTED. |
