Abstract

Abstract

In order to study the hysteretic behavior of the rotational friction damper under static cyclic loading, the quasi-static test of six rotational friction dampers was carried out. The working mechanism, hysteresis performance, energy dissipation capacity and friction coefficient were analyzed. The numerical simulation was carried out by using ABAQUS finite element software. The results were compared with the experimental results. The results showed that:1)rotational friction damper had full hysteretic curve and good energy dissipation capacity; 2)the friction of asbestos-free organic matter was relatively stable, and the friction dispersion of Al-Mg alloy and Cu-Zn alloy dampers was relatively large; 3)increasing the pre-tightening force of high-strength bolts and the number of elements of the damper could increase the friction force of the damper and effectively improve the energy dissipation capacity of the friction damper; 4)the energy dissipation capacity of Al-Mg alloy was better than that of Cu-Zn alloy and asbestos-free organic matter, the energy dissipation stability of asbestos-free organic matter was better than that of Cu-Zn alloy and Al-Mg alloy; 5)the friction coefficient of Cu-Zn alloy and Al-Mg alloy was greater than 0.3, the friction coefficient of asbestos-free organic matter was about 0.16; 6)the error between the finite element analysis results and the test values was small, the finite element model could simulate the test well.
