0 The Force vs. displacement diagram shows the two level 1. The facts defining damper: work of the damper strengthened by +-55mm and provided with deformation control feature. Fig.6 shows the three level work of the damper in elasticity zone, in deformation control zone and in post-collapse zone with deformation and force control.

2. Dampers parameters are: - Diametar (% reduction, minimum 20%) - Length reduction (corresponding max strain 10%) ״Roughness of element “dog bone- Fig1 . - Elements for local and gobal buckling (for work in compression, concrete, lead, aluminium plate, and element for sliding) - C and γ –material and damper constants The problem is how to describe histeresis loop with large displacements and in situation when the acting force is small, because the relation are not more applicable. Hystereses loop is defined by: : Fig.3. Testing at Military Institute-VTI Belgrade Manson-Coffine Law, (VERY LOW CYCLE FATIGUE) • Δεp - the cyclic plastic strain range (accumulated strain) and • Nf - the number of cycles to failure and Fig . 2 • F (σ,ε), hystereses line Force vs. displacement
