On the importance of soil damping for tall buildings loaded by wind

In this paper, the overall damping as function of the velocity of vibration of two tall structures subjected to wind is studied. The overall damping ratio is studied by means of two simple, but representative and complementary models and it is compared with that identified in two buildings in The Netherlands. In the models, the soil-structure...

Identification of energy dissipation in structural joints by means of the energy flow analysis

In this paper, identification of energy dissipation in the joints of a lab-scale structure is accomplished. The identification is carried out by means of an energy flow analysis and experimental data. The devised procedure enables to formulate an energy balance in the vicinity of the joints to obtain local energy dissipation. In this paper, a...

Evaluation of the applicability of the Lugre model for modelling the dynamic behaviour of bolt connected frames

Nowadays buildings are becoming taller but also lighter and more slender. Those characteristics make buildings more sensitive to dynamic loads. Damping is an important but most uncertain parameter in the dynamic response of buildings under wind excitations. As a consequence, several researchers attempted to study it. Davenport [1] defined the...
