Shake table testing of a low damage steel building with asymmetric friction connections (AFC)

摘要

This 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 dynamic properties of the test structure are determined using snap-back tests. The behavior of the test frame to ground motions was consistent with standard methods to estimate peak displacements, and residual displacements. When beam ends and the base-column joints were modelled by trilinear and bilinear hysteresis loops respectively, the response with time matched numerical simulations well. Residual drifts were 0.2% for peak inter-story drifts up to 3%, and 0.7% for peak inter-story drifts of 6.0% and the structure was able to manually restraightened. (C) 2019 Elsevier Ltd.
