A schematic of the column-to-base plate connection investigated is shown in Fig. 1. The traditional calculation methods are based upon the recommendations presented in AISC Design Guide 1 (Fisher and Kloiber 2006). ... However, if plate washers are used, the strength reduces with increasing base plate thickness. The traditional calculations ...
a base plate hole is enlarged, the washer plate size will also need to be increased to bridge over the enlargement. It should be noted that washer plates may be need to transfer forces from the column into the foundation. If this is the case, the washer plate size and necessary welding will need to be designed by the EOR. ADDRESSING ANCHORS
Following customer requests, the scope of US base plate design is extended to include welded plate washers. The primary design advantage of these is to equalize the shear …
A 3/8" thick plate washer and a regular F436 washer can be used instead. The plate washer doesn't need to be hardened; Written April 19, 2011, modified October 29, 2014. . https:// (column to beam) if not why? Reply. Dane McKinnon says: February 16, 2018 at 9:09 am
Forces in T-stubs of the base plate Assuming that tension is resisted on the line of the bolts and that compression is resisted concentrically under the flange in compression, the lever arms from the column centre can be calculated as follows: z t = 380/2 = 190 mm z c = (276.3 – 25.3)/2 = 125.5 mm In this design situation, the left flange is in tension and the right in …
9. 2 / DESIGN GUIDE 1, 2ND EDITION / BASE PLATE AND ANCHOR ROD DESIGN The vast majority of building columns are designed for axial compression only with little or no uplift. For such col- umns, the simple column-base-plate connection detail shown in Figure 1.1 is sufficient. The design of column-base-plate connections for axial compression only is …

Grouting helps you to model columns to the top of concrete parts and place the base plate correctly. It also makes it easier to dimension the detail in GA drawings.
An adequate washer (see 7.2.4) should be provided for each anchor rod. Because these hole sizes are recommended as maximum sizes, the use of smaller hole sizes is often …
weld anchor rod plate washers to the base plate. For a column that is also subject to lateral loads, it depends on what load path you are anticipating to get the lateral loads from the column to the foundation. If you are planning to transfer the column shear into the foundation through the anchor rods, then I recommend the washers for those ...
Next, it is detailed the configurations adopted for elements in contact with the semi-rigid connection, such as plates, beam, column, bolts, washers, and nuts. The frictional contact type was used for the lateral contact region between nut-washer 1, washer 1-column, column-plate, plate-washer 2, and washer 2-bolt, as displayed in Fig. 3.4.
Column base plate connections are the critical interface between the steel structure and the foundation. These con- nections are used in buildings to support gravity loads and function as part of lateral-load-resisting systems. ... The …

See the section on Base Plate Bending Strength for rod layout restrictions related to columns in uplift; When welded plate washers are used only 2 rows of rods are allowed. Base plate position - The column base plate can only be concentrically placed about the major axes of the steel column, so that there is no eccentricity in the line of ...
AISC Table 14-2 allows grossly oversized holes in a column base plate, which requires a plate washer. I can't find anything that says the plate washer has to be developed by field welding it to the base plate. In my particular case that I am looking at, my columns are pinned base, and are embedded 10" into the slab blockout.
