Abstract: “A. KMITA The purpose of this work is to present some aspects and main problems of theory and computations of RC (reinforced concrete) bridge slabs. The differential equation of the cracked bridge slab, using the classical variational method is worked out. The equation of bridge slab deflection with the boundary conditions and compatibility conditions in the crack are obtained. The total differential equations in the class of the general functions are shown. In this model the effect of discontinuity of the first derivative of deflection functions is taken. The numerical results of an approximate method of solutions of RC cracked plates with boundary element method (BEM) are shown.”
