A theoretical study of the rigidities of slabs with
circular voids oriented in the longitudinal and in the transverse
direction is discussed. Equations are presented for predicting the
bending and torsional rigidities of the voided slabs. This paper
summarizes the results of an extensive literature search and initial
review of the current methods of analyzing voided slab. The various
methods of calculating the equivalent plate parameters, which are
necessary for two-dimensional analysis, are also reviewed. Static
deflections on voided slabs are shown to be in good agreement with
proposed equation.
