ASDIP STEEL is a structural engineering software for design of steel members and connections. ASDIP STEEL software includes the design of shear connections based on the AISC 360 provisions. Following is an overview of the graphical user interface and the required steps for shear connection design, with annotated screenshots of the software.

ASDIP Graphical User Interface

ASDIP interface consists of two panes. The left pane is dedicated to the data input, and the right pane is for the results. Both panes include tabbed pages to organize the information is a logical and productive way. ASDIP provides graphical controls such as buttons, check boxes, text boxes, radio buttons, etc, to simplify the data input. In addition, the menu bar and the tool bar provide useful options to navigate throughout the software easily.

Shear connection design steps

In the Geometry tab enter the sizes, dimensions, and all geometric information of the connection. At the top of the page select the connection type: either single angle, double angle, single plate, or tee. The program will automatically update the graphical interface to reflect the selection.

At the bottom of the page, click on the Support tab to specify the support type, either column flange, column web, or beam web. Click on the AISC Sections button to select the support steel section from the built-in AISC sections database. If there is a similar connection at the other side of the support, then check the corresponding box to specify that the support will have twice the load. 

Click on the Beam tab to enter the beam dimensions. The beam size can be selected from the AISC sections database as well. If the beam is coped, check the corresponding box for the top flange and bottom flange. The program will use this information in the calculations.

A tab for the connector will show up depending on the connection type. For single-angle and double-angle connections click on the Angle tab to enter the related information. In this tab you can enter the angle dimensions and eccentricity. The angle can be either bolted or welded to the support and to the beam. If bolted, specify the bolt edge distance. Similar information is required for the other types of connectors, such as single-plate or tee.

Depending on whether the connector is bolted or welded, the Bolts tab and Weld tab will show up to enter the corresponding geometric information.

In the right pane, the At-a-Glance tab show a summary of the results, with the most relevant information, organized by topic. This is useful for a quick identification of any problem in the design.

In the Materials tab specify material properties for support, beam, and connector, such as Fy and Fu. In the Bolts tab enter the bolt diameter and material specification. In the Weld tab enter the fillet weld leg size and electrode strength.

The Condensed tab shows a more detailed set of results, organized by topic. This is useful when more information is required, for example the full list of the geometric constraints checks. The program shows the design strength of all the applicable limit states, and it identifies the controlling limit state. Likewise, the program calculates the factored loads per load combination, and it identifies the controlling load combination, as show above.

In the Loads tab you can specify either a single set of pre-combined loads, or a set of nominal load cases to be combined internally. The first option applies when the loads come from another software and they are already combined, for example the beam reaction for 1.2D+1..7L. In this case enter this load as a pre-combined load and the software will use this load without any additional load factor.

Specify the load combinations code, either ASCE 7-05 or 10/16. Select the steel design method philosophy, either ASD or LRFD. The required load information is the vertical load P acting at the end of the beam, as shown above.

The Detailed tab shows full detailed results, step-by-step calculations with exposed formulas and Code references. It includes the detailed calculation of the design strength of every applicable limit state. This is useful for a granular check of the shear connection design and for submittals to approval agencies.

ASDIP STEEL generates scaled graphics of front, side, and top views with the corresponding dimensions. and a summary of the design ratios, for final check, as shown above.

Takeaway

ASDIP STEEL includes the design of shear connections, with multiple options to optimize the design easily. The design of shear connections may be cumbersome and error-prone, with multiple limit states checks. With the friendly user interface the design can be completed and optimized with ASDIP STEEL in minutes.

  • It would be nice to add bolt staggering between support leg and beam web leg, so the length of the angle is shown correctly in the calculation, otherwise it works flawlessly.
