longitudinal reinforcement of the section is not less than BS 8110's
minimum limit of 0.4% of bh (see Section 3.5). When the total percentage
of the reinforcement exceeds 6% of bh (see Section 3.5), a warning
message will be printed out.
The input data for the program RCIDSR are: the section details, the
material properties, the increment of x/ h and the maximum xl h to be used.
The program output data are: the steel stresses, a (= Nlfcubh) and {:3
(= Mlfcubh 2 ) for various xlh values. The results are printed out in
tabulated form.
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.
12. 7(b) Program RCIDPR ( = Rectangular
Column; Interaction Diagram;
Parabolic-Rectangular)
Figure 12.7-2 shows the Header of the program RCIDPR, which
calculates the coordinates on the column interaction curve for a rectangular
column section using BS 8110's parabolic-rectangular stress block,
as described in Reference 1.
The input and output for the program RCIDPR are identical to those of
the program RCIDSR (see Section 12.7(a)).
