Abstract
In this work we address some of the present threats posed to engineering structures in putting
them under extreme, transient loading conditions. The case which is studied in detail pertains to
the terrorist attacks brought explosion and impact of large airplane on a massive structure, By
using these case studies, we discuss the issues related to multi-scale modeling of inelastic
damage mechanisms for massive structures, to time integration schemes in the presence multiscale
content in time brought by a particular nature of loading and finally to model reduction
seeking to provide an efficient and sufficiently reliable basis for parametric studies employed
within the framework of a design procedure. Several numerical simulations are presented in
order to further illustrate the proposed approaches. Concluding remarks are stated regarding the
current and future research in this domain.
