Coping involves modifying which beam element to avoid interference?

• A. Flange
• B. Web
• C. Gusset plate
• D. Stiffener

Answer: (A)

Coping is trimming or shaping the end of a beam so it can fit without colliding with nearby members. The part that’s typically modified to achieve this clearance is the flange—the horizontal, flat edge at the end of the beam. By coping the flange, you remove just enough material for the beam to fit around or past another member (like a column, gusset plate, or another beam) without interference. The web—the vertical piece between flanges—generally isn’t modified through coping, since changing its shape would affect shear capacity and isn’t the usual practice. Gusset plates and stiffeners are connection or reinforcement elements, not the part you cope in this context. So the correct choice is the flange.
