Short-time deflections of two-way slabs

Chhangani, O.P. / Lenkei, P.

A method to calculate short-time deflection of two-way slabs of different boundary conditions is presented. The effective moment of inertia function developed by Branson is examined and a modification of the equation proposed in ACI approach is suggested. The method presented herein considers the influence of reinforcement, material properties of both concrete and steel, and physical dimensions of the slab. Thus the deflections corresponding to cracking and service loads can easily be calculated following the equations developed for the slabs of different boundary conditions. Comparison of the method is made with the experimental studies of Hung and Nawy and the results are found to agree satisfactorily with the experimental values.
