Bars of nominal diameter 16 mm are used in compression for an RCC work consisting of M30 grade concrete, for which the design bond stress (τbd) is 1.5 N/mm2. The stress in the bars at design load is 50 N/mm2. What is the development length (Ld) of the bars as per IS: 456-2000? (Note: account for the 25% increase in bond stress for bars in compression.)
