Calculating the Length of Fillet Weld Required for a Connection Subjected to Given Service Dead and Live Loads

June 8, 2017 Abdul Siraj, P.E.

In this post, I will discuss the eleventh example in our steel design course covering bolted and welded simple steel connections. The goal of this steel design example is to calculate the length of fillet weld required for a connection subjected to given service dead and live loads. We are using the 13th edition of the AISC Steel Construction Manual.


The problem statement states,


The connection shown below is subjected to a service dead load of 10 kips and a service live load of 20 kips. If 5/16″ fillet weld of E70XX electrode is used, what is the total length of fillet weld required. Both the gusset and tension members are 1/2″ thick.
