Numerical Analysis of Crosswise Heterogeneous Covering Structures in 3D Class Structure Conditions

The following paper presents the results of analyses of multi-layered elements and thick constructions, as well as simplifications used for solving structures of 2D class models published in specialist literature, and compares them with a different approach involving generalization of pertinent problems into 3D classes. An error estimation method was pro-posed, together with a procedure of shaping grid's density ensuring necessary computing precision. Solving huge sets of equations allowed for practically continuous values of complex functions of stress states. Several of the presented typical examples indicate the possibility of applying the algorithms, among others, to heterogeneous structures of reinforced concrete constructions.
