What is the Steel Connection Tool?

Structural Central's Steel Connection Tool is structural engineering software that allows you to quickly generate the calculations required to determine the strength of a steel connection.

The calculations evaluate each of the possible limit states for the coped beam, bolts, welds, angles, plates, girder and/or column in order to determine which failure mode will control the load-carrying capacity of the design.

Some of the limit states considered include:

Connection Types

Determine the load-carrying capacity of the following connections: Double-Angle, Single-Angle, Tee, Single-Plate, Shear End-Plate, Unstiffened Seated, and Stiffened Seated. These are all of the standard shear connections discussed in the Steel Construction Manual produced by the American Institute of Steel Construction (AISC).

Connection Options

Each connection type comes with many additional options to match your exact needs:

  • Coped beams (top and/or bottom)
  • Bolted, welded, or a combination of both
  • Multiple rows of bolts
  • Supported by girder, column web, or column flange
  • Single-sided or double-sided connections
  • Steel Angle, WT, or Plate seat types
  • Workable gages
  • Standard, oversized, or slotted bolt holes
  • Slip critical bolts

Design Code

Calculate steel connection capacities per the Specification for Structural Steel Buildings (ANSI/AISC 360) which is the Referenced Standard for steel design of the International Building Code (IBC).

Design Criteria

The strength of the connections can be determined using Load and Resistance Factor Design (LRFD) or Allowable Strength Design (ASD).

The strength of the steel shapes, plates, bolts, and welds will use the preferred material specifications by default, or you can select other common specifications, or just set the strengths directly (Fy, Fu, Fnt, Fnv, FEXX).

Factored or Unfactored Loads

The beam reaction can be entered as either a single load or as multiple loads with different load types (Dead, Live, Wind, etc). Multiple loads will be combined automatically using the LRFD or ASD load combinations provided by Chapter 16 of the International Building Code.

What constructability checks are performed?

In addition to determining the capacity for the steel connection you propose, Structural Central's Steel Connection Tool will warn you if it identifies any conditions that do not meet the recommendations found in the Steel Construction Manual.

Connection Constructability Checks
Check IconMinimum and maximum bolt spacing(Sections J3.3 & J3.5)
Check IconMinimum bolt edge distance(Table J3.4)
Check IconMinimum entering and tightening clearance(Tables 7-15 & 7-16)
Check IconMinimum and maximum fillet weld size(Section J2.2b & Table J2.4)
Check IconMinimum fillet weld shelf dimension(Figure 8-13)
Check IconMinimum clearances to make welds(Figures 8-11 & 8-12)
Check IconMinimum clearances between beam, connector, and support(Part 9)
Check IconMaximum fillet encroachment(Figure 10-3)
Check IconMinimum connector length(Part 10)
Check IconMinimum rotational ductility(Part 9)
