Hss column base plate design. The dimension between the anchor bolt and the bending plane is the moment arm to be used in solving for the base plate thickness. Note the aisc design guide 1 base plate design procedure for wf columns if used for hss columns would assume a bending plane at the face of the hss column and the portion of the plate beyond the column as a cantilever. Column section type column section size column section properties. Design of column base plates typical column bases as shown below consist of a single plate fillet welded to the end of the column and attached to the foundation with four holding down bolts.

This results in base plate details that are expensive difficult to fabricate and may even contribute to the hazards. The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out. In articles practical solutions comments 0. Note the aisc design guide 1 base plate design procedure for wf columns if used for hss columns would assume a bending plane at the face of the hss column and the portion of the plate beyond the column as a cantilever.

45 degree progression bending planes vs aisc hss base plate bending planes. When a concentrated tensile or compressive force acts on the end of a round or rectangular hss column with a cap plate and the force is in the direction of the hss axis the walls of the hss member could fail in sidewall yielding with consideration of shear lag. Aisc design guide 1. He dimension between the anchor bolt and the t bending plane is the moment arm to be used in solving for the base plate.

Steel column base plates are one of the most ndamental parts of a steel structure yet the design of base plates is commonly not given the attention that it should by engineers.
