Abstract: A structural assembly includes an elongated support member having an end and a wall extending from the end. The wall has therein, at a location spaced from the end, a transverse opening. An elongated beam is positioned to be connected to the support member at the end thereof, the beam having first and second surface portions. An angle-shaped joining member has first and second outwardly extending wings. The first wing has at least one transverse projection, which extends through the transverse opening in the wall of the support member. The second wing has first and second surfaces. The second wing extends along the beam with the first surface of the second wing confronting the first surface portion of the beam.
