Shear connections between W-beams and HSS-columns include the consideration of additional limit states in the design. This document shows a step-by-step HSS shear connection example using ASDIP STEEL software.

HSS Shear Connection Example

As an example, consider the W14x26 beam connecting to the HSS10x10x5/16 column shown below. The unfactored beam reactions include DL and LL. Design and optimize the shear connection per the AISC 360 provisions.

HSS Shear Connection Example Input

Enter the information given in the statement of the example. Go to the Geometry tab and select Single-Plate as the connector. Click on the Support tab and select the column type as HSS-Column, then select the column size from the steel sections database. Go to the Beam tab and select the beam size W14x26 from the database. Go to the Plate tab and enter the dimensions of the shear plate, in this case plate width = 4" and thickness = 3/8". Finally go to the Bolts tab and specify the number of bolt rows as 4.

Use the Materials tab to enter the material properties for the different components. In this case use Fy = 50 ksi for the beam and plate. Bolts will be 3/4" A325 bolts. Finally, go to the Loads tab and enter the unfactored beam reactions given in the statement of the example.

HSS Shear Connection Example Output

The At-a-Glance tab shows a summary of the design for a quick overview of your work as you go. The green check marks indicate that the checks passed. The Condensed tab shows a condensed set of calculations with the most important information grouped by topic for a more in-depth check. The Detailed tab shows a step-by step detailed set of calculations with exposed formulas and references to the design code.

In this example, the limit state of Bolt Shear Rupture controls the structural capacity of the connection as 52.4 kip considering 4 rows of bolts and 0" eccentricity. The maximum factored combined load is 42.0 kip. The screenshot above shows the limit states and the load combinations for this example.

In addition to the calculation of all the applicable limit states, the program performs multiple design checks required by the code, and it check for any geometric constraints. All the design checks pass with the selected connection; therefore, the design is adequate as shown below.

Takeaway

ASDIP STEEL includes the design of HSS Shear Connections, with multiple options to model and optimize the design easily. This HSS shear connection example shows that the design can be completed and optimized using ASDIP STEEL in minutes.
