Deviations Due to the Discrete Modeling of the Structures

Binsar H. Hariandja, Ika Bali

Abstract


Real existing structures are generally complicated in geometry that might make them unsuitable or difficult for
the analyses. Several assumptions or simplifications are usually made by the practitioners to make them simpler and
may be analyzed in ease. The assumptions and/or simplifications might make the analyses much easier; however,
they might create some deviations from the true behavior of the structures, which are in fact, are not known precisely
to the analysts. The paper discusses some examples for simplifications in the analysis or the structural systems. The
examples include the types of the simplifications, and the deviations that caused by them. The types of
simplifications are in the case of material behavior, the geometry of the system, an in the case of connectivity of the
structural components. The results signify the importance of wisdom in the setting of the simplifications and the
assumptions to make the analyses easier but with dependable results.
