	Human-structure interaction We present a new human-structure interaction (HSI) model of walking on a flexible surface. A human is considered as a mass point, located at the body’s Center of Mass (COM). The mass moves along a predefined trajectory, which deforms together with the surface on which the human walks.
	Dynamics of structures with semi-rigid joints This topic comprises numerical and experimental investigations of flexible connections. Besides elastic effects, I take into account contact and friction mechanisms between joined structural elements and between structural elements and their connector bolts.
	Computational structural dynamics My work in this area includes implementation of numerical algorithms for modelling of the dynamics of complex structural systems. The employed techniques include dynamic substructuring, model order reduction, and parallel computing.
	Vibration control of guyed masts and Numerical simulation (avi file) This research area concentrates on the development of control algorithms for improving structural response to critical loads, like wind gusts impacting slender cable structures.
	On-line dynamic load identification In this project an attempt was made to identify dynamical loads acting on a structure from acceleration measurements. For this purpose, an algorithm based on a recursive Kalman filter was proposed.
	Optimal design This research area pursued the development of computationally efficient algorithms for optimal design of engineering structures, composed of many groups of structural elements chosen from a discrete catalog. The proposed algorithms were based on graph methods introduced by the group of Prof. Gutkowski.
