Errata List AISC Steel Construction Manual, 13th Edition, Second Printing
The following list represents corrections that have been made in the Third Printing of the 13th Edition of the Steel Construction Manual. Page(s) 1-34 1-34 1-56 1-58 1-108 1-108 2-12 Item Table 1-5: Replace “C8x18.7” with “C8x18.5.” Table 1-5: For a C6x13, the dimension T is 4a in. Table I-8: The WT10.5x28.5 should onlyhave references to note “c” and not note “c, h.” Table I-8: The WT8x20 and the WT8x18 should only have references to note “c” and not note “c, h.” Note “h” should be removed from the bottom of the table. Table 1-16: Replace “C8x18.7” with “C8x18.5” Table 1-16: Replace the rx values with the values given in the attached Table 1-16. The table at the bottom of the page should be revised and is shownbelow: Load Ratio from Step 3 (times 1.6 for ASD, 1.0 for LRFD) Design Story 0 Drift Limit H/100 1 H/200 1 H/300 1 H/400 1 H/500 1 2-21 2-47 5 1.1 1 1 1 1 10 1.1 1.1 1 1 1 20 1.3 1.1 1.1 1.1 1 30 1.4 1.2 1.1 1.1 1.1 40 1.3 1.2 1.1 1.1 50 1.3 1.2 1.2 1.1 60 1.4 1.3 1.2 1.2 80 1.4 1.3 1.2 100 1.5 1.3 1.3 120 1.4 1.3

For the section “Steel Castings and Forgings” the “ASTM A148 grade 80-35” shouldread “ASTM A216 grade 80-35.” A reference should be added alphabetically between SSPC and Tide, and should read as follows: Thornton, W.A., 1992, “Eliminating the Guesswork in Connection Design,” Proceedings of the AISC National Steel Construction Conference, pp. 24-1 – 24-21, AISC, Chicago, IL.

Table 3-10: The Available ASD Moment label on the vertical axis between “176” and “184” should read “180” rather than “188.” Table 3-11: Replace “C8x18.7” with “C8x18.5.” Table 3-11: Replace “C8x18.7” with “C8x18.5.” Table 3-13: Replace this table with the attached Table 3-13. Table 3-21: For the Deck Perpendicular condition, “Strong studs per rib”should read “Strong studs per rib (Rp=0.75)” and “Weak studs per rib” should read “Weak studs per rib (Rp=0.60).” Table 4-1 and Table 4-2: Replace the Properties, “Pex(KL2)/104 ” and “Pey(KL2)/104 ” with “Pex(KL)2/104 ” and “Pey(KL)2/104.” Table 4-4: The units for the radius of gyration should read “in.” Table 4-4: The last value of Effective Length, KL, should read “30.” Table 4-7: The units for theProperties, rx and ry, should read “in.” Table 4-9: The weight per foot should read as follows:
