Homogeneity on Designing the Structural Systems

Abstract

The paperwork presents the analysis over the effects of the variation of constitutive materials’ characteristics in the elastic designing of the structural systems. It has been analyzed the transformation of the actions into sectional efforts using the given techniques by the mechanic materials and static of structures. For the structural analysis it has been used the finite elements technique and also the stiffness matrix method. In this case it is found out that the stiffness matrix of an elastic structure depends essentially on E, on the shape and geometrical dimensions of finite elements. The case study from the last part of this paperwork illustrates the random aspect of elasticity modulus.
