The appliance of interval calculus in estimation of plate deflection by solving Poisson's bisquared partial differential equation

Abstract

The work analyzed the appliance of interval calculus connected to estimation of elements deflection done by reinforced concrete. The simply supported reinforced concrete plate was taken as an example. The plate was loaded by load per unit area. Knowing that there are several parameters that influence the plate deflection, we showed the calculus where the mentioned parameters were given at a certain interval. The results (the final values of deflection) we also got in the form of intervals so it was possible to follow the direct influence of a change of one or more entering parameters on deflection values by using one model and one caculus.
