Numerical model for analysis of stress-ribbon bridges

Abstract

A newly developed numerical model for the analysis of stress-ribbon bridges under the short-term (static and dynamic) and long-term loads and actions is presented in the paper. The model can simulate main nonlinear effects of the behaviour of these structures, including nonlinear behaviour of materials, change in the structure geometry, phased construction, prestressing, etc. Basic solutions for the stress-ribbon bridge over the Cetina River near Zadvarje, and some results of its calculation using the developed numerical model, are presented.
