CHECKING ROBUSTNESS FOR A CONCRETE ROADWAY VIADUCT
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2012, Vol 57, Issue 1
Abstract
Experts’ pursuits in constructions are connected now with the structural robustness’ notions and how to prevent the partial, full or disproportioned collapse. The question: “What is robustness?” has by far no unitary and simple answer. For bridge’s structures there are no specific directives for robustness’ calculation. Even in COST – Robustness of Structures – TU0601 experts’ discussions, bridges problem was less exemplified because of the every structure uniqueness. The object of this study is a concrete roadway viaduct, with eight spans, for two traffic lanes. This paper focuses on two questions: (i) How the use of a type or another of finite element will influence the initial damage’s modelling. (ii) The effect of the initial failure type for the inherent dynamic response of the structure and, actually, what element for that answer – the value of the inherent period or the form of the eigenvalue – is more susceptible for the initial type of failure.
