1、Revisions and Errata List AISC Steel Design Guide 24, 1stPrinting (Printed Copy) October 15, 2012 The following list represents corrections to the first printing of AISC Design Guide 24, Hollow Structural Section Connections. Page(s) Item 10 The reference to the equation nwwRFA should be “Spec. Eq.

2、J2-3” instead of “Spec. Eq. I2-3.” 53 Equation 5-16 should be revised as follows to correct the denominator: 22rwcPwBF 53 Equation 5-21 should be revised so that alpha cannot be taken as negative. Replace Equation 5-21 with the following: 2(/)10rpKP nt 55 Figure 5-9 should be revised so that the con
