Abstract
Two alternative passive seismic protection technologies have been combined in a
single experiment to assess their synergy. The first, a nonlinear-elastic posttensioned
tendon frame, uses steel tendons to connect structural elements. Joints
can rotate elastically allowing large recoverable interstory sway. Such structures
have limited energy dissipation capabilities but are able to re-centre themselves
after a seismic event. The second, a metallic shear panel energy dissipator has a
large energy dissipation capacity but, as it is unable to self-centre, may impart a
residual sway or offset to a structure after a seismic event.
This paper presents a series shaking table tests conducted at ¼ scale to assess the
coaction of these technologies under realistic seismic loading. Repeat testing is
used to investigate the fatigue lifecycle. While challenging to perform, the tests
reveal the technologies to be complementary, each contributing beneficial
characteristics to the global response.
