The input data for the program BDFLCK are: the type of section, the
support condition, the section details, the characteristic strength of the
reinforcement and the loading information. The program output data are:
the basic span/depth ratio, the modification factors, the actual and
allowable span/depth ratios.
Comment
The complete listing of the above program (with commentary), together
with the floppy disks, are obtainable from the Publishers. See Section
12.1(a) and Appendix 1.

Program BCRKCO ( = Beam CRacK
COntrol)
Figure 12.5-2 shows the Header of the program BCRKCO, which
calculates the maximum tension bar spacings ab and ac in Fig. 5.4-1, as
described in Section 5.4. If the overall depth of the section exceeds 750
mm, the size of side bars required is also calculated. The program
calculates the allowable tension bar spacings from eqn (5.4-2) instead of
using the data in Table 5.4-1.
