Reinforcing Bar: Reinforcement Shape Codes To BS8666:2005

The document discusses reinforcement bar shape codes according to British Standard BS8666:2005. It provides 28 different shape codes that are defined by geometric formulas involving the bar dimensions of length (L), width/diameter (A, B, C, etc.). Any shapes not defined by these codes are designated as shape code 99 and require fully dimensioned sketches. It also includes a table with minimum dimension requirements for different nominal bar sizes.
