| | 3RD REVIEW |
| | DATE: FRI. DEC. 08/2017 |
| | ACTION: DENIED |
| | |
| | 1) A E-MAIL WAS SUBMITTED FROM BRIAN BULLOCK ON |
| | 12/05/2017 THAT WAS ASKING ABOUT FIRE RATINGS OF |
| | PRIMARY STRUCTURAL MEMBERS, ENCASED IN A FLOOR CEILING |
| | ASSEMBLY, BEAMS BENEATH THE FIRE RATED FLOOR CEILING |
| | ASSEMBLY, RATING OF COLUMNS CARRYING THE 2ND FLOOR |
| | LOADS. |
| | |
| | PLEASE SEE THE RESPONSE SENT ON 12/06/2017: |
| | |
| | I BELIVE YOU ARE REFERRING TO TABLE 601 OF THE 2014 |
| | FBC-B WITH BUILDING TYPE VB CONSTRUCTION. YOU REFERENCE |
| | THAT YOU ARE CREATING A HORIZONTAL FIRE BARRIER BETWEEN |
| | THE UPSTAIRS R2 OCCUPANCY AND THE 1ST FLOOR MERCANTILE |
| | WHICH IS REQUIRED BY TABLE 707.3.10. |
| | THE FLOOR/ CEILING ASSEMBLY IS TO MAKE A 2 HOUR FIRE |
| | BARRIER FROM THE EXTERIOR WALL TO EXTERIOR WALL, THE |
| | EXTERIOR BEARING WALLS WILL MAKE THE 2 HOUR FIRE RATING |
| | WITH THE BLOCK WORK STUCCO ON THE EXTERIOR AND DRYWALL |
| | ON THE INTERIOR. THE EXTERIOR DOORS DO NOT NEED TO BE |
| | FIRE RATED UNLESS BY REQUIREMENTS FOUND IN TABLE 705.8. |
| | |
| | IF THERE ARE COLUMNS AND OR PRIMARY FRAMING MEMBERS |
| | BELOW THE 2 HOUR HORIZONTAL FIRE BARRIER THEN THEY ARE |
| | TO BE FIRE RATED THE SAME AMOUNT OF TIME. THE PRIMARY |
| | FRAMING MEMBERS CANNOT FAIL BEFORE THE 2 HOUR FLOOR |
| | CEILING ASSEMBLY, OTHERWISE THE FLOOR ASSEMBLY WOULD |
| | COLLAPSE. PLEASE SEE THE DEFINITION OF PRIMARY |
| | STRUCTURAL FRAME. |
| | |
| | PRIMARY STRUCTURAL FRAME. THE PRIMARY STRUCTURAL FRAME |
| | SHALL INCLUDE ALL OF THE FOLLOWING STRUCTURAL MEMBERS: |
| | |
| | 1. THE COLUMNS; |
| | |
| | 2. STRUCTURAL MEMBERS HAVING DIRECT CONNECTIONS TO THE |
| | COLUMNS, INCLUDING GIRDERS, BEAMS, TRUSSES AND |
| | SPANDRELS; |
| | |
| | 3. MEMBERS OF THE FLOOR CONSTRUCTION AND ROOF |
| | CONSTRUCTION HAVING DIRECT CONNECTIONS TO THE COLUMNS; |
| | AND |
| | |
| | 4. BRACING MEMBERS THAT ARE ESSENTIAL TO THE VERTICAL |
| | STABILITY OF THE PRIMARY STRUCTURAL FRAME UNDER GRAVITY |
| | LOADING SHALL BE CONSIDERED PART OF THE PRIMARY |
| | STRUCTURAL FRAME WHETHER OR NOT THE BRACING MEMBER |
| | CARRIES GRAVITY LOADS. |
| | |
| | 707.5 CONTINUITY. |
| | FIRE BARRIERS SHALL EXTEND FROM THE TOP OF THE |
| | FOUNDATION OR FLOOR/CEILING ASSEMBLY BELOW TO THE |
| | UNDERSIDE OF THE FLOOR OR ROOF SHEATHING, SLAB OR DECK |
| | ABOVE AND SHALL BE SECURELY ATTACHED THERETO. SUCH FIRE |
| | BARRIERS SHALL BE CONTINUOUS THROUGH CONCEALED SPACE, |
| | SUCH AS THE SPACE ABOVE A SUSPENDED CEILING. JOINTS AND |
| | VOIDS AT INTERSECTIONS SHALL COMPLY WITH SECTIONS 707.8 |
| | AND 707.9 |
| | |
| | 707.5.1 SUPPORTING CONSTRUCTION. |
| | THE SUPPORTING CONSTRUCTION FOR A FIRE BARRIER SHALL BE |
| | PROTECTED TO AFFORD THE REQUIRED FIRE-RESISTANCE RATING |
| | OF THE FIRE BARRIER SUPPORTED. HOLLOW VERTICAL SPACES |
| | WITHIN A FIRE BARRIER SHALL BE FIREBLOCKED IN |
| | ACCORDANCE WITH SECTION 718.2 AT EVERY FLOOR LEVEL. |
| | |
| | 1012.5.1.1 FIRE WALL ALTERNATIVE. 3. THE |
| | FIRE-RESISTANCE RATING OF THE FIRE BARRIERS AND |
| | HORIZONTAL ASSEMBLIES SHALL NOT BE LESS THAN THAT |
| | SPECIFIED FOR FIRE WALLS IN TABLE 706.4 OF THE FLORIDA |
| | BUILDING CODE, BUILDING. |
| | |
| | EXCEPTION: WHERE HORIZONTAL ASSEMBLIES ARE USED TO |
| | LIMIT THE MAXIMUM ALLOWABLE AREA, THE REQUIRED |
| | FIRE-RESISTANCE RATING OF THE HORIZONTAL ASSEMBLIES |
| | SHALL BE PERMITTED TO BE REDUCED BY 1 HOUR PROVIDED THE |
| | HEIGHT AND NUMBER OF STORIES INCREASES ALLOWED FOR AN |
| | AUTOMATIC SPRINKLER SYSTEM BY SECTION 504.2 OF THE |
| | FLORIDA BUILDING CODE, BUILDING ARE NOT USED FOR THE |
| | BUILDINGS. |
| | |
| | I BELIEVE THE DESIGNER OF RECORD HAS NOT USED THE AREA |
| | INCREASE IN HEIGHT OR AREA FOR FIRE SPRINKLERS, IT |
| | WOULD HAVE TO BE VERIFIED THE FIRE SPRINKLER SYSTEM IS |
| | A FULL NFPA 23 SYSTEM, NOT A 13R, IF THE NFPA 13 FIRE |
| | SPRINKLER IS INSTALLED THEN THE 1 HOUR REDUCTION CAN |
| | OCCUR TO THE FLOOR / CEILING ASSEMBLY AS WELL AS THE |
| | PRIMARY FRAMING MEMBERS AND COLUMNS TO ONE HOUR FIRE |
| | RESISTANCE RATING. |
| | |
| | SHEET A001D INDICATES THE BUILDING TO HAVE A NEW FIRE |
| | SPRINKLER SYSTEM, THE TYPE OF SYSTEM IS NOT DECLARED? |
| | SHEET A-102D THE REFLECTIVE CEILING PLAN INDICATES |
| | DROPPED SECTIONS FOR STEEL BEAMS BUT THE PLANS DO NOT |
| | INDICATE HOW THE PRIMARY FRAMING (STRUCTURAL) MEMBERS |
| | ARE TO BE FIRE RATED? |
