A study is presented of the nonlinear behaviour of a system of ductile steel plates subjected to bending cyclic loads which could be used as a seismic damper. Evaluation is carried out through laboratory tests, and a nonlinear analytical model is presented. The mechanical properties and deformation capacity of dissipation of the system of steel plates are determined from the experimental data, and a mathematical technique is proposed to fit the data to an analytical model. The results show that, using this technique, the hysteretic model proposed can predict the force–displacement relationship of the plates and the hysteretic energy dissipated by the nonlinear behaviour of the plates.Key words: seismic damper, experimental data fit, analytical load–displacement, laboratory tests, analytical model.

The Cost

In this work, a recently patented seismic damper to be applied to structures composed by systems of panels is presented. In particular, the article is devoted to characterize the behaviour of the proposed connector by means of an experimental and numerical analysis and to provide some information about the cost of the elements needed to realize the damper, accounting for the manufacturing process. The experimental analysis has regarded five specimens tested under different loading conditions, and it has been used as a term of comparison with the classical systems of connection currently employed in these structures. Afterwards, in the article, a design criterion able to control the capacity and ductility of the device by simply varying the shape of the damper is presented and its accuracy is evaluated by performing finite element analyses. The results of the experimental and finite element analyses are very promising in terms of cyclic behaviour and energy dissipation capacity and reveal that the design of the element can be accurately controlled by means of the proposed approach. Furthermore, the cost estimate has revealed that the proposed damper is also cheaper than the classical solutions with a cost reduction of about 40%.
