Dr.-Ing. Amir Hossein Arshian is the current head of research department. The focus of our research activities are mainly about extreme structural engineering where we evaluate the performance of structural systems subjected to severe dynamic loading scenarios such as earthquake, impact, explosion and progressive collapse.
We are expert in using nonlinear FEM approaches for diverse structural engineering problems from seismic recalculation of existing buildings to design of protective structures. Beyond the traditional nonlinear approaches such as implementation of rigid-plastic hinges, we are capable of considering physical nonlinearity problems such as cracking, crushing, tension-stiffening, yielding, strain-hardening and rupturing as well as large displacement – small strain geometrical nonlinearity problems for reinforced concrete and steel structures through implementation of nonlinear fiber-based modeling approach. Furthermore, we are capable of performing sensitivity and uncertainty analyses using probabilistic variance-based approaches in order to quantify uncertainties, to provide a decision model for target confidence level and to estimate the probability of failure.
