1、Revisions and Errata List AISC Steel Design Guide 10, 1stprinting (Printed Copy) October 15, 2012 The following list represents corrections to the first printing (1997) of AISC Design Guide 10, Erection Bracing of Low-Rise Structural Steel Buildings. Page(s) Item 27 In the left column, the second eq
2、uation, “F = 3.73(1.54)(11.5)(Af) = 8.61(Af)” should be replaced with “F = 3.73(1.54)(1.5)(Af) = 8.62(Af).” (Note: this correction appears in the online PDF version of this publication.) 29 Equation 5-1 should read: 10.2NBS P LA(0.9)E 33 Near the middle of the right column, the sentence beginning “P
3、er Caltrans.” should read: Per Caltrans (9) the maximum cable drape (A) should be 2.75 in. In the 9thline from the bottom of the right column, the corresponding calculation of P should read: 22.75P (0.84)(40) 8 0.84712866 lbs.The horizontal and vertical components of the preload force are 734 pounds
4、 and 460 pounds, respectively. 34 In the left column, 2ndline, the calculation for 1should read: 10.2 45,400 866 47.20.216 0.9 13,000,0000.15 ft(Eq. 5-1) The calculation in the 3rdline from the bottom of the left column should read: sin a sin 0.9 25 0.393 ft At the top of the right column, replace the first 8 lines with the following: 81,120 0.393R251, 275 lbs. 1, 275 47.51 40 1,514 lbs. Cable force including P effects: 11,013 1,514 866 13,393 lbs. Cable force: 13,393 lbs. Allowable cable force = 45,400/3 = 15,133 13,393 lbs. Therefore, use a in. diameter cable.
