Tech Tip: Stabilizer Plates in SDS/2

According to the AISC 14th Edition Manual, stabilizer plates in an extended shear plate configuration are not required when the required shear strength is equal to or less than the available strength to resist lateral displacement. (Please refer to the Requirement for Stabilizer Plates section found in the AISC 14th Edition Manual on Page 10-105 for more information on these requirements.)

When designing connections using either the ASD 14 or LRFD 14 design methods, SDS/2 takes these AISC requirements for stabilizer plates into consideration to determine if they should be provided or not. You can choose to ignore these requirements and always provide stabilizer plates by turning on the option Always provide stabilizer plates, found in Job or Fabricator Options, as shown in Figure 1.

When stabilizer plates are provided, if half the column flange minus k1 distance is less than 4 inches, the stabilizer plates extend to the column web. Otherwise, they extend from the k1 distance to the toe of the flange. In SDS/2 2015, you can force the stabilizer plates to extend to the column web by setting the option Extend stabilizer plates to Web, found in Connection specifications, as shown in Figure 2.

Customer Profile: Johnson Machine Works, Inc.

Chariton, Iowa-based Johnson Machine Works, Inc.'s portfolio includes not only structural steel fabrication for commercial buildings, but heavy fabrication projects as well. Those projects typically consist of fabrication with tight tolerances, machined surfaces and machined components.

The company's work on the Saylorville Lake/Big Creek Diversion project highlights some of these specialties, and showcases the flexibility of SDS/2.

The $9.3 million project involves replacement of the slide gate structure at Big Creek Lake Diversion Dam, which has been inoperable since 1998. The dam gate is one of several flood-control structures that protect Polk City, Iowa, residents during high water events.

Although some of the machined components are not what the software was designed to do, Johnson Machine Works' Jason Unger points out that, "the capabilities available to the SDS/2 user with features such as turned solid element and material fuse have proven to be very valuable in creating axles, shafts, bushings, wheels and other turned features with chamfered edges."
