ABSTRACT

The applied low cyclic reversed loading scheme is shown in Figure 4, and the hysteretic responses of specimen with different friction forces are shown in Figure 5. Because the servo hydraulic test system produced asymmetric loading displacements in tension and in compression, asymmetric responses were observed during the tests, but the PS-SCED

bracing system still can exhibit stable and repeatable self-centering responses with effective energy dissipation throughout the entire loading protocol. The results also demonstrate that the energy dissipation capability of the brace is enhanced with increasing friction force.
