Lecture 15 - Page 1 of 7 Lecture 15 – Welded Connections (cont.) The design of a typical all-welded double-angle simple shear connection will be investigated. Similar to an all-bolted connection, the AISC manual makes use of a one-stop-shopping design aid Table 10-3 p. 10-48 for all design considerations. An example design of a typical all-welded double-angle simple shear connection is as follows: Example 1 (LRFD) GIVEN: A W21x44 A992 girder with a factored end reaction = 87 KIPS has 2 – L3x3x3/8 connection angles shop-welded to the girder web and field-welded to the W12x58 A992 column flange as shown. REQUIRED: Design the connection and provide a summary sketch. 2X weld size Weld B L = ? Weld A 3/16 L2x2x¼ erection angle shop-welded to col. flange W21x44 Girder W12x58 Column ¼ L = ? 2 – L3x3x3/8 connection angles Minimum Web thickness
