Soonhwang Choi,Sooyong Park,Vijayan Sugumaran few decades. System identification is the process of modelling dynamical systems mathematically using measurements of input and output signals. Extended Kalman filter (EKF) or unscented Kalman filter (UKF) are commonly used to identify the structural properties. EKF cannot estimate the state and pa

Jon Atle Gulla,Hans Olaf Borch,Jon Espen Ingvaldsen of the art approach of engineering and design, to reach targeted seismic resilience for structures. There are various methods of adding extra damping to structures that may be used to reduce structural and non-structural damage. Metal yielding type damping systems are sometimes selected among many

Pavel Makagonov,Alejandro Ruiz Figueroa,Alexander Gelbukhculation is developed with an additional stress–strain state stage. It helps to solve the problem of a stochastic crack. The absence of transition from a state of continuity to the state of “section with a crack” does not allow to make uniform the calculation of strength, stiffness, and fracture tou

Jordi Conesa,Veda C. Storey,Vijayan Sugumarann. Life would be much simpler if we had a suitable text book with methods and computer programmes which we could keep referring to. Therefore, we have presented here material that is essential for mathematical modelling of some complex geological situations, with which earth scientists are often con
