ASDIP STEEL is a structural engineering software for the design of structural steel members. It includes the design of shear connections based on the AISC 360 provisions. This document is a step-by-step design example of a beam-to-girder single plate connection.

Single plate connection example

As an example, consider the partial framing plan shown below, which is part of the second floor of a retail building. All member sizes have been specified as 16" deep due to clearance limitations, which will force to cope the beams at top and bottom. Design the single plate connection of the beams to the girder for the given reactions.

Design Steps

1.- Enter the known information, such as the support member size. The connection will be to a beam web. The At-a-Glance tab shows a summary of the design for a quick overview of your work as you go. Note that ASDIP STEEL shows the applicable limit states with a pass / fail indicator. Likewise, it shows the loads combinations and the applicable design checks. With this information it's really easy to identify the controlling limit state and load combination.

2.- Enter the beam size, given in the problem statement. Since all members have the same height, it's necessary to cope the top and bottom flanges of the beams. This is important since some special limit states apply to coped beams. The Condensed tab shows a more complete set of results grouped by topic, great for a more detailed overview of your design. Note it presents more useful information, such as the controlling limit state and load combination, etc.

3.- Enter the connector properties. This includes the plate size, eccentricity to the beam CL, and edge distances to the bolts. ASDP STEEL lets you specify if the plate is bolted or welded to the beam. In this example the plate will be shop welded to the girder and field bolted to the beam. The Detailed tab shows a complete set of step-by-step calculations with exposed formulas and with references to the AISC code. Note that the calculations are organized by topic, and per limit state, for a granular checking of the results.

4.- Enter the loads given as beam reactions in the problem statement. ASDIP STEEL lets you specify either a single pre-combined load, or a set of load cases, In this example the known loads are by load case, and will be combined per ASCE 7-10. The design can be either per ASD or LRFD. The Graph tab shows graphically the connection details in front, side, and top views. The design summary shows the satisfactory results.

Takeaway

ASDIP STEEL includes the design of different types of shear connections, with multiple options to model and optimize the design easily. This single plate connection example shows that the design can be completed and optimized within minutes.
