AISC Design Guide 1: Base Plate and Anchor Rod Design, 2006 Edition

This 2nd edition of the AISC Design Guide 1: Base Plate and Anchor Rod Design guide has been created to assist engineers and fabricators in the design, detailing and specification of column-base-plate and anchor-rod connections, in a manner that avoids common fabrication and erection problems. The updated content in this design guide is based on the 2005 AISC Specification for Structural Steel Buildings (AISC 2005) and includes design guidance in accordance with both Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD).

Topics covered in AISC Design Guide 1 include material selection, fabrication, erection, and repairs, guidance on base plate and anchorage design for compression, tension, and bending, guidance on the design of anchors for fatigue applications, and design examples on all common design cases, presented side-by-side for both ASD and LRFD.
