Fig. 12.8-2 Header of program SCRKCO
The input data for the program SCRKCO are: the section details, the
characteristic strength of the reinforcement and the moment redistribution
ratio. The program outputs the allowable tension bar spacing.
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.
12.8(c)
Program SSHEAR (=Slab SHEAR)
Figure 12.8-3 shows the Header of the program SSHEAR, which designs
the shear reinforcement for a slab, as described in Section 8.7. The
program SSHEAR allows the user to specify:
(1) the type of shear reinforcement (i.e. either links or bent-up bars);
(2) the size or spacing of links.
With reference to (2), if the user specifies the link size, then the program
calculates and outputs the link spacing; however, if the user specifies the
link spacing, then the program will output an appropriate link size up to
size 16 mm. The bent-up bars are designed using the equation given in
Table 3.17 of BS 8110.
The input data for the program SSHEAR are: the section details, the
characteristic strengths of the materials and the design ultimate shear
force. The output data from the program SSHEAR are: the design shear
