Abstract

Highlights: We examine near-regular (quasi-symmetric) structures with local modification. We decompose any general load to cyclic and asymmetric load. We use up to four symmetry components. We aim to show this method can be used in case of other symmetry group Civ . Abstract: This work aims to discuss the static analysis and reanalysis of near-regular (quasi-symmetric) structures and to develop further the analysis of these structures based on the principle of general connect (coupling) and the group representation theory with symmetry groups C3v and C1v . During the analysis, only one-dimensional irreducible representations of different symmetry groups are taken into account, and we investigate the effect of these to the static analysis and to local modification method, as well. For these structures any general load can be decomposed into cyclic and asymmetric load, furthermore at most four symmetry components SSS, AAA (C3v ) and S, A (C1v ) ( S – symmetric component, A – antimetric component) are used in this paper. The mentioned methods were applied for static analysis with two perpendicular symmetry planes; this paper examines the effect of three symmetry planes and considers the applicability in case of more-than-three symmetry planes for analysis.
