| | DENIED BY BUILDING |
| | PLEASE ADDRESS THE ITEMS NOTED BELOW: |
| | |
| | 1) [ NOT RESOLVED. ] SUBMIT A STRUCTURAL ANALYSIS WITH |
| | CALCULATIONS TO SHOW THAT THE EXISTING STRUCTURE CAN |
| | SAFELY SUPPORT THE PROPOSED EQUIPMENT FOR DEAD AND LIVE |
| | LOADS. FBC 1603.1.8 SPECIAL LOADS |
| | SPECIAL LOADS THAT ARE APPLICABLE TO THE DESIGN OF THE |
| | BUILDING, STRUCTURE OR PORTIONS THEREOF, INCLUDING BUT |
| | NOT LIMITED TO THE LOADS OF MACHINERY OR EQUIPMENT, |
| | THAT ARE OF GREATER MAGNITUDE THAN THE LOADS DEFINED IN |
| | THE SPECIFIED FLOOR AND ROOF LOADS SHALL BE SPECIFIED |
| | BY THEIR DESCRIPTIONS AND LOCATIONS. |
| | FBC 1604.4 ANALYSIS |
| | LOAD EFFECTS ON STRUCTURAL MEMBERS AND THEIR |
| | CONNECTIONS SHALL BE DETERMINED BY METHODS OF |
| | STRUCTURAL ANALYSIS THAT TAKE INTO ACCOUNT EQUILIBRIUM, |
| | GENERAL STABILITY, GEOMETRIC COMPATIBILITY AND BOTH |
| | SHORT- AND LONG-TERM MATERIAL PROPERTIES. |
| | |
| | MEMBERS THAT TEND TO ACCUMULATE RESIDUAL DEFORMATIONS |
| | UNDER REPEATED SERVICE LOADS SHALL HAVE INCLUDED IN |
| | THEIR ANALYSIS THE ADDED ECCENTRICITIES EXPECTED TO |
| | OCCUR DURING THEIR SERVICE LIFE. |
| | |
| | ANY SYSTEM OR METHOD OF CONSTRUCTION TO BE USED SHALL |
| | BE BASED ON A RATIONAL ANALYSIS IN ACCORDANCE WITH |
| | WELL-ESTABLISHED PRINCIPLES OF MECHANICS. SUCH ANALYSIS |
| | SHALL RESULT IN A SYSTEM THAT PROVIDES A COMPLETE LOAD |
| | PATH CAPABLE OF TRANSFERRING LOADS FROM THEIR POINT OF |
| | ORIGIN TO THE LOAD-RESISTING ELEMENTS. |
| | |
| | THE TOTAL LATERAL FORCE SHALL BE DISTRIBUTED TO THE |
| | VARIOUS VERTICAL ELEMENTS OF THE LATERAL |
| | FORCE-RESISTING SYSTEM IN PROPORTION TO THEIR |
| | RIGIDITIES, CONSIDERING THE RIGIDITY OF THE HORIZONTAL |
| | BRACING SYSTEM OR DIAPHRAGM. RIGID ELEMENTS ASSUMED NOT |
| | TO BE A PART OF THE LATERAL FORCE-RESISTING SYSTEM ARE |
| | PERMITTED TO BE INCORPORATED INTO BUILDINGS PROVIDED |
| | THEIR EFFECT ON THE ACTION OF THE SYSTEM IS CONSIDERED |
| | AND PROVIDED FOR IN THE DESIGN. A DIAPHRAGM IS RIGID |
| | FOR THE PURPOSE OF DISTRIBUTION OF STORY SHEAR AND |
| | TORSIONAL MOMENT WHEN THE LATERAL DEFORMATION OF THE |
| | DIAPHRAGM IS LESS THAN OR EQUAL TO TWO TIMES THE |
| | AVERAGE STORY DRIFT. WHERE REQUIRED BY ASCE 7, |
| | PROVISIONS SHALL BE MADE FOR THE INCREASED FORCES |
| | INDUCED ON RESISTING ELEMENTS OF THE STRUCTURAL SYSTEM |
| | RESULTING FROM TORSION DUE TO ECCENTRICITY BETWEEN THE |
| | CENTER OF APPLICATION OF THE LATERAL FORCES AND THE |
| | CENTER OF RIGIDITY OF THE LATERAL FORCE-RESISTING |
| | SYSTEM. |
| | |
| | EVERY STRUCTURE SHALL BE DESIGNED TO RESIST THE |
| | OVERTURNING EFFECTS CAUSED BY THE LATERAL FORCES |
| | SPECIFIED IN THIS CHAPTER. SEE SECTION 1609 FOR WIND |
| | LOADS, SECTION 1610 FOR LATERAL SOIL LOADS AND SECTION |
| | 1613 FOR EARTHQUAKE LOAD |
| | |
| | 2) [ NOT RESOLVED. ] PROVIDE THE WINDLOAD DESIGN DATA |
| | FOR THE PROPOSED ROOF TOP EQUIPMENT INSTALLATION. THE |
| | VULT WINDSPEED FOR THE CITY OF WEST PALM BEACH IS 170 |
| | MPH AND THE EXPOSURE CATEGORY IS C. FBC 1603.1.4 |
| | |
| | 3) PLEASE SUBMIT A RESPONSE LETTER INDICATING HOW EACH |
| | OF THE REVIEW COMMENTS HAS BEEN ADDRESSED. |
| | |
| | NEW COMMENT: |
| | |
| | 4) THE LETTER FROM SPAN ENGINEERING IS REQUIRED TO BE |
| | SIGNED AND SEALED BY A FLORIDA LICENSED ENGINEER. THE |
| | EXISTING PLATFORM THAT WILL BE REUSED WILL HAVE TO BE |
| | EVALUATED BY A FLORIDA LICENSED ENGINEER TO DETERMINE |
| | IF IT CAN RESIST A 170 MPH WIND LOAD IN EXPOSURE C. |
