Shake Table Testing of a Low Damage Steel Building with Asymmetric Friction Connections (AFC)

The paper describes the shaking table performance of a half-scale two-story steel moment frame with asymmetric friction connections (AFCs) at the column bases and at the beam ends. The results showed that the beam ends and the base-column joints exhibited bilinear and trilinear response respectively. Residual drifts were less than 0.2% for shake table trials up to 3% peak inter-story drift. Even at a peak inter-story drift of 6.5%, the residual drift response was still only 0.7%.
