materials and the loading information. The program first checks that the

percentage of compression steel specified is within BS 8110's allowable

limits for rectangular beams (see Section 4.10), before it outputs the areas

of reinforcement, and the ratios of x/d and zld at the ultimate limit state.

If the percentage of tension steel required, or the xld value or zld value,

does not satisfy BS 8110's requirements, warning messages will be printed

out.

12.5(a) Program BDFLCK ( = Beam DeFLection

ChecK)

Figure 12.5-1 shows the Header of the program BDFLCK, which checks

whether the span/depth ratio of a rectangular or flanged beam section is

within BS 8110's allowable limit, as described in Section 5.3. Instead of

using the data in Tables 5.3-2 and 5.3-3, the program calculates the

modification factors for the tension reinforcement and the compression

reinforcement from the equations given in BS 8110: Clauses 3.4.6.5 and

3.4.6.6 (see also eqns 5.3-1(a) and (b)).
