Summary
Simulation of real structural behaviour is a powerful tool, which helps engineers in the assessment of existing bridges as well as while designing new ones. ATENA is specifically developed for the advanced analysis of reinforced or pre-stressed concrete structures. The newest version of the software has been released in November 2008. The new version builds upon the great success of the previous versions and includes many new exciting features, which are especially useful for the analysis of concrete bridges. ATENA unique features are embraced by engineers in more than 40 countries all over the world. ATENA builds on the long tradition and experience of its developers in the numerical modelling of reinforced concrete structures. The program founder was among the first researchers that introduced the concept of nonlinear modelling of concrete behaviour into the finite element method [1]. This in depth understanding of reinforced concrete modelling resulted in several unique features of the software:
