lb) Hook

Figure 8.6(a) shows anchorage of tensile reinforcement being achieved using a straight bar. It should be noted that EC2 does not permit straight anchorage or bends for smooth bars of more than 8 mm diameter.

Note:

The CEB-FIP Model Code(16) gives a factor of 1.0 for lbnet as opposed to 2/3 in EC2. Designers may wish to consider using the higher value.

Typical values for anchorage length and support width, w, can be obtained for (a) and (b) in Figure 8.6.
