Plans (3)M C2012-00491 GENERAL NOTES 1. WHERE BRACE ELEMENTS ARE THROUGH -BOLTED, THE MOUNTING HOLE IN THE ELEMENT IS TO BE NO MORE THAN 1116' IN DIAMETER LARGER THAN THE BOLT OR THREADED ROD. 2. AVOID BRACING TO STRUCTURAL ELEMENTS WHICH MAY RESPOND DIFFERENTLY INA SEISMIC EVENT. 3. THE ENGINEER OF RECORD FOR THE BUILDING SHALL REVIEW THE ISAT ATTACHMENT DETAILS AND LOADS TO DETERMINE THE SUITABILITY OF THE STRUCTURETO ACCEPT SUCH LOADS PRIOR TO INSTALLATION OF THE SEISMIC BRACING SYSTEM. 4. WHEN UTILIZING CABLE BRACING FOR OTHER THAN VIBRATION ISOLATED SYSTEMS, TENSION THE CABLE TO REMOVE SLACK WITHOUT INDUCING UPLIFT OF THE SUSPENDED ELEMENT. CABLE INSTALLATION IS TO BE SYMMETRICAL 5. AS A GENERAL RULE, DO NOT MIX RIGID BRACING AND CABLE BRACING IN THE SAME RUN. HOWEVER, ONCE BRACING HAS MADE A 90 DEGREE CHANGE IN RUN DIRECTION, THE BRACING TYPE MAY SWITCH FROM RIGID TO CABLE OR VICE VERSA. 6. BRACING TABLES IN THE ISAT MANUAL ARE BASED ON A NOMINAL BRACE ANGLE OF 45 DEGREES FROM HORIZONTAL +/.2.5 DEGREES. BRACE ANGLES LESS THAN 45 DEGREES AREACCEPTABLE WiTHOUr MODIFICATION. BRACE ANGLES GREATER THAN 47.5 DEGREES AND LESS THAN 50 DEGREES FROM HORIZONTAL ARE ACCEPTABLE; HOWEVER, THE TABULATED BRACE SPACING AND ANCHORAGE LOADS WILL REQUIRE MODIFICATION BY ISAT TECHNICAL SUPPORT. 7. BRACING MAY BE INSTALLED WITH UP TO +P 7-% DEGREES VARIATION FROM'TRUE'TRANSVERSE OR TRUE' LONGITUDINAL ALIGNMENT WITHOUT THE NEED FOR ADDITIONAL ENGINEERING. REFER TO INSTALLATION DETAILS. 8. UN -BRACED SUSPENDED UTILITIES ARE TO HAVE A 6' MINIMUM CLEARANCE TO CEILING SUPPORT WINES. 9. SEISMIC BRACING MAY NOT PASS THROUGH A STRUCTURAL SEISMIC SEPARATION JOINT. UTILITY SYSTEMS THAT PASS THROUGH A SEISMIC SEPARATION JOINT MUST BE SEISMICALLY RESTRAINED WITHIN 5 FEET OF BOTH SIDES OF THE SEPARATION OR WITHIN 5 FEET OF POINT OF CONNECTION OF ANY HARDWARE DESIGNED TO ACCOMMODATE SEISMIC MOVEMENT ACROSS THE SPAN OF THE SEPARATION JOINT. 10. WITH THE APPROVAL OF THE ENGINEER OF RECORD, UTILITY SYSTEMS THAT ARE SUSPENDED FROM THE OVERHEAD DECK MAY BE BRACED TO CONCRETE SHEAR WALLS PROVIDED THAT THE WALLS AND THE OVERHEAD DECK WILL RESPOND SIMILARLY DURING A SEISMIC EVENT.
