FOR USE OF THE LOAD _TABLE HERE —IN, THE FOLLOWING SHALL APPLY, 1. FOR CURTAIN WALL DETAILS, SEE DRAWING 1789 OR 1790. 2. SEE THE ELEVATION ON SHEET 1 FOR FRAME MEMBER LOAD WIDTH, SPAN & ANCHOR TYPE REFERENCE. NOTE THAT THE LOAD WIDTH "W" VALUE USED IN THE LOAD TABLE FOR ANY CORNER FRAME MEMBER SHALL BE THE LESSER OF LOAD WIDTH AT THE LEFT & RIGHT SIDE OF THE CORNER. 3. THE LOAD TABLE HERE -IN HAS BEEN DEVELOPED USING A SIMPLIFIED CONSERVATIVE DESIGN APPROACH TO DETERMINE ALLOWABLE DESIGN PRESSURES FOR EACH MULTI -SPAN CURTAIN WALL ANCHOR AND VERTICAL FRAME MEMBER REINFORCEMENT CONDITION. IF A MORE EXACT COST EFFICIENT APPROACH IS DESIRED TO DETERMINE CURTAIN WALL MEMBER REINFORCEMENT REQUIREMENTS, ANCHOR REQUIREMENTS, AND ALLOWABLE LOADS, REFERENCE TO SHEET 2 & 3 OF DRAWING 1789 OR 1790 SHALL BE MADE. 4. WITH INTERMEDIATE VERTICAL FRAME MEMBERS, REGARDLESS OF WHETHER OR NOT THIS LOAD TABLE REQUIRES REINFORCEMENT IN THE MEMBERS, THERE SHALL BE A MINIMUM OF A 36" LONG SECTION OF R1 REINFORCEMENT PLACED AT EACH INTERMEDIATE WIND & DEAD LOAD ANCHOR LOCATION CENTERED WITH THE ANCHOR. 5. VERTICAL FRAME MEMBER SPLICE LOCATIONS SHALL BE WITHIN 1/3 THE SPAN DISTANCE (L/3) FROM A SUPPORT BUT NO CLOSER THAN 18" FROM THE CENTERLINE OF INTERMEDIATE WIND OR DEAD LOAD ANCHORS (MUST STAY 18" AWAY FROM SUPPORT TO ALLOW FOR THE REQUIRED REINFORCEMENT SPECIFIED IN NOTE #4). EXAMPLE: IF THE SPAN BETWEEN SUPPORTS IS 12 FT., THE SPLICE SHALL OCCUR NO MORE THAN 12/3 = 4 FT. & NO LESS THAN 18" FROM A SUPPORT. 6. VERTICAL MEMBER SPLICES MAY NOT OCCUR WITHIN THE TOP MOST OR BOTTOM MOST SPAN OF ANY CURTAIN WALL UNLESS THEY ARE A DISTANCE OF L/3 (+/-10%) FROM THE WIND OR DEAD LOAD ANCHOR. 7. FOR USE OF THIS TABLE, VERTICAL MEMBER REINFORCEMENT, WHEN REQUIRED, MUST RUN FULL HEIGHT OF THE WALL SPLICED ONLY AT VERTICAL FRAME MEMBER SPLICE LOCATIONS. END SET BACK FROM TOP & BOTTOM OF THE WALL MAY BE UP TO 18". SET BACK FROM A SPLICE SHALL BE WITHIN 6" OF THE SPLICE. 8. WHEN DETERMINING THE ALLOWABLE PRESSURE FOR A FRAME MEMBER TOP & BOTTOM END SUPPORT, THE LARGEST OF THE END AND ITS ADJOINING SPAN SHALL BE USED AS THE APPLICABLE SPAN LENGTH IN THE LOAD TABLE. 9. WHEN DETERMINING THE ALLOWABLE PRESSURE FOR AN INTERMEDIATE WIND OR DEAD LOAD ANCHOR, THE LARGEST OF THE SPANS ON EITHER SIDE OF THE SUPPORT SHALL BE USED AS THE APPLICABLE SPAN LENGTH IN THE LOAD TABLE. 10. WHEN DETERMINING THE ALLOWABLE PRESSURE FOR A FRAME MEMBER, IF SPANS VARY BETWEEN SUPPORTS, THE LARGEST SPAN SHALL BE USED AS THE APPLICABLE SPAN LENGTH IN THE LOAD TABLE. HOWEVER, IF MULTIPLE ADJOINING SPANS ARE SMALLER THAN OTHER SPANS, THE SMALLER ADJOINING SPANS MAY BE CONSIDERED IN THIS LOAD TABLE PER THE SPAN DIAGRAM ON SHEET 3. NOTE THAT WHEN A SMALLER SPAN ADJOINS A LARGER SPAN, THE LARGER SPAN MUST BE USED WHEN DETERMINING REINFORCEMENT AND LOAD REQUIREMENTS FOR THE ADJOINING SMALLER SPAN. 11. PARAPETS (TOP OF WALL FRAME MEMBER CANTILEVER) MAY APPLY PROVIDING THE HEIGHT OF THE PARAPET ABOVE THE TOP MOST WIND OR DEAD LOAD ANCHOR DOES NOT EXCEED THE LESSER OF 1/3 THE SPAN LENGTH BELOW THE ANCHOR OR 48". WHEN DETERMINING THE ALLOWABLE PRESSURE FOR THE PARAPET EXTENSION & THE ANCHOR BELOW THE PARAPET, THE LARGER SPAN EXISTING BELOW THE ANCHOR SHALL BE USED AS THE APPLICABLE SPAN LENGTH IN THE LOAD TABLE. 12. VERTICAL MEMBER REINFORCEMENT, WHEN REQUIRED IN A PARAPET EXTENSION, SHALL EXTEND UP PAST THE TOP MOST SUPPORT A MINIMUM OF 2/3 THE LENGTH OF THE PARAPET EXTENSION. INSTRUCTIONS OF USE OF MULTI —SPAN LOAD_ TABLE: 1. READ & UNDERSTAND ALL NOTES ON THIS SHEET. 2. DETERMINE THE APPLICABLE SPAN LENGTH FOR THE VERTICAL FRAME MEMBER BEING CONSIDERED. MAY CONSIDER ALL SPANS OF ONE VERTICAL MEMBER EQUAL TO THE LARGEST SPAN ALONG THAT MEMBER OR CONSIDER SPANS BASED ON THE EXAMPLE SHOWN ON SHEET 3. 3. DETERMINE THE LOAD WIDTH FOR THE FRAME MEMBER BEING CONSIDERED PER THE ELEVATION ON SHEET 1. 4. ENTER THE LOAD TABLE ON SHEET 4 OR 5, CHECK EACH FRAME MEMBER TYPE, CHOOSE THE LEAST REINFORCED ONE THAT MEETS THE JOB REQUIRED DESIGN PRESSURE & USE THAT MEMBER OR ONE WITH MORE REINFORCEMENT. 5. CHECK EACH APPLICABLE ANCHOR TYPE TO INSURE IT MEETS THE JOB REQUIRED DESIGN PRESSURE. 6. REPEAT STEPS 2 THROUGH 5 FOR EACH VERTICAL FRAME MEMBER. `ov111111/ll, oft J No. 44135 �ilop ew r RTIF T TITLE ,N M NO.
