# AISC J10.2 Web Local Yielding

## AISC J10.2 Web Local Yielding

(OP)
I'm going through some hand calculations on a Beam to Column moment connections and there is something in this section that doesn't make sense to me.

The column capacity for web local yielding is given by equation J10-2:
Rn = (5k+N)*Fy*tw

I am trying to make sense of AISC's comment that N is "not less than k for end beam reactions".

Are they talking about the k of the column or the beam? If they're talking about the k of the column then why should this affect the value of N? It doesn't seem to make physical sense to me.

If they're talking about the beam's k distance, then does this apply to my moment connection? Or, do they mean a different type of connection when they refer to "end beam reactions".

### RE: AISC J10.2 Web Local Yielding

It doesn't apply to your moment connection. They're talking about the minimum required bearing length for beams supported by direct bearing on the bottom flange, such as for a beam supported by a stiffened seat (page 10-93 in the 13th edition manual).

### RE: AISC J10.2 Web Local Yielding

I believe end beam reactions means a beam sitting on a seat-type simple shear connection. No column involved.

Thank you both!

The more I looked at it the more I was convinced that it did not apply to my connection. But, then I really wanted to understand what types of connections it would apply to. Seated shear connections makes more sense than anything else. Though the 'k' distance still seems like an odd that they're using k rather than k1.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why itâ€™s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
