FEM modeling of spatial structural systems in evaluation of the real structural performances

Abstract

The paper is a review of enhanced concept of CASA (Computer Aided Structural Analysis) software application in FEM modeling of spatial structural systems of bridges, buildings, industrial facilities, machine devices, etc. in evaluation procedures of real structural performances. Contrary to everyday engineering design circumstances, which comprehend, primarily, respect of technical regulations, FEM modeling in case of structural evaluation, needs, in some sense, alternative type of creativity. Chosen examples could be illustrative for this attitude.
