Fig P$10\mathrm{.}3$ shows a typical interior region of a prestressed concrete floor that a to be designed as a flat plate, using unbonded post$-$tensioned tendons. There will be column capitals or dropped panels. Service live load is $80$ psf$,$ dead load consists of self$-$weight plus $20$ psf superimposed. $($a$)$ Find the required slab thickness, tendon profile, required prestress force per ft$,$ and spacing of tendons in the colume sad middle strips. A two$-$way banded tendon arrangement is specified Prestress should be based on a balanced load consisting of self weight plus superimposed dead load $($b$)$ Find the concrete stresses at all critical sections resulting from applicanom of dead plus service live load. $($c$)$ Determine the size, spacing, and length of all required non$-$prestressed bonded flexural steel $($d$)$ Check the flexural strength of the slab, and modify the design, if necessary Note that, according to ACI Code, if the

line load does not exceed three$-$fourths of the dead load, m moments may be anned to occur at all with des entire slab system. $($e$)$ Check for shear transfer at a typical panel reinforcement a required, use $45$ degree bent bus $($se Ref. $19341)($ deffection at the center of a typical panel when the full service live load is in place?

Tendons will be $0\mathrm{.}500-$in diameter Grade $250$ unbonded strands and f$\text{'}$c$=5,000$ psi and f'ci$=3,500$ psi Assume $20$ percent time dependent loss.FIGURE P$10\mathrm{.}3$
