Fig. 12.9-1 Header of program PSBPTL
with the floppy disks, are obtainable from the Publishers. See Section
12.1(a) and Appendix 1.
12.9(b) Program PBMRTD (=Prestressed Beam;
Moment of Resistance; Tabulated Data)
Figure 12.9-2 shows the Header of the program PBMRTD, which
calculates the moment of resistance of a rectangular prestressed beam
section with bonded tendons using tabulated data, as described in Section
9.5. The program is also applicable to flanged sections in which the neutral
axis lies within the flange.
The input data for the program PBMRTD are: the section details, the
characteristic strengths of the materials and the effective prestress. The
program output data are: the ratios of[puAps/fcubd,fpb/0.87/pu,fpe/[pu and
xld, and the moment of resistance Mu·
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.
12.9(c) Program PBSUSH (=Prestressed Beam;
Symmetrical; Unreinforced; SHear)
Figure 12.9-3 shows the Header of the program PBSUSH, which
calculates the required ratio of link area to link spacing for a symmetrical
and unreinforced prestressed beam section, as described in Section 9.6.
