Designing a simple beam shear connection is easy and quite simple, of course. All that an engineer needs to do is to determine the beam end reaction and then simply design the connection. That's it. Magic!
However, the beam end reaction is not always available on some design drawings provided by some 'unruly' clients. Oftentimes, as a result, we get frustrated over a generic design note on a design drawing which says: design beam shear connections using half the capacity of beam. Determining half the beam capacity, which is simply equal to the beam reaction, really takes some time. As always, we are referred to Table 3-6 of the AISC Steel Construction Manual. There, we look for the value of the maximum total uniform load that corresponds to a given beam span. Interpolation or extrapolation is the name of this boring task.
If you hate going through Table 3-6 of AISC Steel Construction Manual and also hate doing the cumbersome interpolation in calculating beam end reaction, this one engineering tool is for you.

| CR | Reaction Magnification Factor in Percent (Composite Beam) | uw | Maximum Total Uniform Load | |
| LB | Beam Span | Ra | Maximum Beam End Reaction |
Notes:
- LS_F is the span of beam that corresponds to 'Shear - Flexural' Yielding boundary. Shear Yielding governs below this span. Flexural Yielding governs above this span.

Input for the length of beam, LB, can be accomplished in several ways. Input can be either in decimal or imperial/architectural format. If you enter, for example, 144.5 or 144.5", the number is automatically converted to 1'- 1/2". If you enter 144.5', the number is converted to 144'-6". A number without a trailing apostrophe or quotation mark is read in inches.
You may also enter a number in imperial (FIS) format containing fraction and decimal. For example, if you enter 1.5'-1 1/2", the number is converted to 1'-7 1/2". If you enter 1.5'-1.5", the number is also converted to 1'-7 1/2".
Unrecognized input format, however, is automatically interpreted and converted to ZERO.
I'm not sure why but this site is loading very slow for me. Is anyone else having this problem or is it a problem on my end? I'll check back later and see if the problem still exists. safety decking
