This paper presents a simple but relatively accurate procedure for the analysis of unbonded prestressed continuous
flat slabs. Bi-circular curves instead of conventional parabolic ones are introduced to obtain the characteristic
parameters of the curved tendon profiles. Based on the proposed tendon profile and theory of thin plates, a
series of simple formulae are derived to compute the bending moments of flat slabs. The validity of the proposed
method is demonstrated by comparing the results with those obtained from finite element analysis. The results of
the analysis presented in this paper indicate that the proposed method turns out to be convenient and reasonably
accurate in the analysis of prestressed flat slabs. Copyright © 2004 John Wiley & Sons, Ltd.
