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. 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. Aug 2012 by dan mazzei p e. He dimension between the anchor bolt and the t bending plane is the moment arm to be used in solving for the base plate.

Base plate design based on code abbreviation. Aisc design guide 1. Aisc design guide 1. Base plate and anchor rod design 2nd edition.

Column section type column section size column section properties. Column section type. The forces and deformations from the structural analyses used to design the column base plate connection are dependent on the choice of the column base plate connection details.

Aisc design guide 1. 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. Hss column cap plate connections limit state of wall local yielding. This results in base plate details that are expensive difficult to fabricate and may even contribute to the hazards.

Of the column base plate connection in the elastic and plastic ranges and for seismic loading possibly even the cyclic force deformation relations. Csa a23 3 14 design of concrete structures. 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. 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.
