Computational methods for structures

Abstract

The principal goal in the design of any general engineering structure is to achieve stability. A structure must remain stable and therefore, fit for purpose, throughout its useful life. This requirement can be achieved with the help of structural analysis techniques, which nowadays can be performed using computers. In this paper, the authors consider the three distinct phases of structural analysis, namely Idealisation, Analysis and Interpretation. The idealisation phase describes the process of translating the proposed engineering works into a model that represents the physical response of the structure to applied loading. This model is a simplification of the real structure and only considers the characteristics of the components that have the greatest influence on its stability. In the following phase, the analysis phase, the aforementioned model is used to study and understand how the structure might behave in reality. The framing of this model may draw upon knowledge obtained in many other disciplines, including Applied Mathematics and Materials Science. The significance of the results are determined during the interpretation phase and the engineer either decides that stability can be achieved or works through the process again, modifying the initial idealisation. As computers continue to grow in capability, it is the purpose of this paper to consider the role of computational methods and how they may empower present and future structural engineers.
