What letter is used for beams in the plan drawings?

• A. B
• B. L
• C. I
• D. T

Answer: (A)

Beams are labeled with the letter B on plan drawings to identify each member type clearly in the layout. This simple labeling lets you quickly reference the beam schedule for exact dimensions, reinforcement details, and placement without crowding the drawing. Other letters are used for different member types—L for lintels, I for I-beams, and T for T-beams—so you can tell at a glance what each line represents. Knowing this convention helps you map the plan information to field work accurately. So, the letter used for beams in plan drawings is B.
