Hence required anchorage, 0f-)/bnet at a direct support Figure 5.12 = (f-)/b X 4740/9650 = 500 mm > 0.3/b OK

Anchorage up to face of column = 600 - 75 = 525 mm OK

The anchorage may be increased to I if preferred, by providing a bend at the end of the bar.

The requirement for transverse reinforcement along the anchorage length does 5.2.3.3 not apply at a direct support.

Secondary reinforcement ratio for top steel 5.4.3.2.1 p2 > 0.2pi = 0.2 x 0.00476 = 0.00095

Use T16 @ 250 mm crs. (804 mm2/m) transversely in top

The reinforcement details are shown in Figure 7.6.
