This second-edition 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. This new 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).
