Post-tensioning design

[shalini...@gmail.com]

This is with reference to a paper on "Guidelines for the design of
Post-Tensioned Floors" published in Concrete International in March
2003.

It is mentioned that one of the criteria for design of post-tensioning
is percentage of dead load to balance (this is also one of the design
criteria in ADAPT-PT software).Wherein the post tensioning is
converted into an equivalnet balanced loading,

My question is that suppose we balave dead load by some amount say
60%, then what idea is this conveying to the engineer/designer?

Is it that by balancing the amount of dead load he is keeping a check
of deflections in transfer stage?(where the structural system is
subjected to dead load plus pre-stress)

Further,

I have another question:

1.In a reserach problem on post tensioned floor design, we are
modeling the tendon as an eccentric element placed in a 2-D plate.

Now, my question is that suppose I place a tendon with 1KN pre-
stressing force in the plate and get the set of internal forces(say
"Y") due to this tendon, then,

A. IF I want the internal forces due to 100 KN force will it be "Y"
multiplied by 100? (since I am doing linear elastic analysis)
B.Further if use "N" tendons (each tendon with 100 KN force) spaced
uniformly, will the internal forces then be "Y" multiplied by "100"
multiplied by "N"?
