Hss column base plate design.

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. Aisc design guide 1. 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. 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.

Designing column base plates for uplift. Of the column base plate connection in the elastic and plastic ranges and for seismic loading possibly even the cyclic force deformation relations. Aisc design guide 1. Column section type column section size column section properties.

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. Hss column cap plate connections limit state of wall local yielding. Base plate design based on code abbreviation.

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.

The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out. Aisc design guide 1. Csa a23 3 14 design of concrete structures.
