Page / Line / Correction
6 / In Figure 1.4 caption “spandrel” under left beam is misspelled
30 / load combinations 3, 4, 7 with roof should be (roof or snow)
31 / load combinations 2, 3, 4 with roof should be (roof or snow)
81 / 21 / reference on definition of Ubs should be to Chapter 10, not Chapter 7
136 / 23 / rib= “radius of gyration if” should be “radius of gyration of”
143 / Ex. 6.1 line 9 / = 560 in.4 should be in.3
144 / In Figure 6.5 the PNA should be moved up into flange
144 / Ex. 6.2 line 18 / In equation, the (8.82-7.75) should be (8.82- 7.55) with changes in calculated numbers accordingly
147 / Ex. 6.4a line 12 / Ma should be Mu
158 / Ex 6.5b lines 29 & 31 / Mp/W should be Mn/W
159 / Ex 6.5b lines 6, 7 & 9 / Mp/W should be Mn/W
163 / Ex. 6.6 Last line / kip-ft should be ft-kips
172 / Ex. 6.9 line 19 / Missing before 2.3(8.85..)
224 / 2 / should be
224 / 22 / Rm=1 should be RM=1
227 / Step 5, Correct the value of the load in B1 calculation. The 354 should be (354+99)
229 / Step 5, Correct the value of the load in B1 calculation. The 280 should be (280+62)
235 / Ex. 8.4a line 19 / The reference to Table 6-2 should be to Table 6-1
242 / Ex 8.5 step 10 should have included wind moment. This requires additional calculations.
244 / 12 / Pr =2.1 should be Pr =22.1
257 / Ex. 8.7a line 5 / Dead load should be 113 kips and live load should be 45 kips

270 / 15 / “less that this” should be changed to “less than this”
304 / 6 / Units on EIeff should be in.2-kips
339 / Prob 12 figure, the left side break line should only be in outer two plates
346 / Step 7 typo on calc of shear rupture, 1.96 should be 1.69, answer is correct
349 / Correct angle in Fig 11.3 top. The 2 angles are not shown with the same leg length and should be.
354 / Fig. 11.4 right / Both angles should be welded to the beam web in the section
358 / End of step 5 / fRn should be Rn/W
375 / Fig 11.12 kdet the units are in wrong place.
392 / Prob 19 correct W360 to W36
392 / Prob 20 make it a bolted-welded connection
392 / Prob 29 add 3/4 in. bolts to the problem data
392 / Prob 30 make the WT7x24 a 9 in. long element and change Fig. ref to 11.19
408 / 9 / Change Fy/Ft to Fy/Fu
420 / Ex. 12.4b line 9 / fRn should be Rn/W
