A structural drawing indicates reinforcement as '6-#8'. What does this notation specify?
Correct Answer
A) 6 pieces of #8 rebar
The notation '6-#8' indicates 6 pieces of Number 8 reinforcing bar. The number before the dash indicates quantity, and the number after indicates the rebar size designation.
Why This Is the Correct Answer
The notation '6-#8' follows standard reinforcement notation where the number before the dash indicates quantity and the number after the hash symbol indicates the rebar size designation. Therefore, '6-#8' specifies 6 pieces of Number 8 reinforcing bar. This is the standard format used in structural drawings throughout the construction industry for indicating reinforcement requirements.
Why the Other Options Are Wrong
Option C: 8 pieces of #6 rebar
This reverses the notation format. The '6' comes before the dash and indicates quantity, while '#8' indicates the rebar size designation. Reading it as '8 pieces of #6 rebar' incorrectly interprets the 8 as quantity and 6 as size, which is backwards from the actual notation standard.
Option D: #8 rebar with 6-inch cover
This misinterprets the notation as spacing information. The '6-#8' format indicates quantity and size, not spacing. Spacing would typically be shown differently on drawings, such as '#8 @ 8' O.C.' or similar notation that specifically indicates on-center spacing measurements.
Memory Technique
Remember 'Quantity-#Size': The number before the dash is always the quantity (how many), and the number after the # is always the rebar size designation.
