Experimental Study on Seismic Behavior of Steel Column Base Connections with Arc End-Plates Slip-Friction

This paper proposes a new type of steel slip-friction column base connections with arc end-plates. Two end-plates the base, which can slide between each other to some extent, were set at position where is subject plastic deformation. Thus, sliding-friction energy dissipation effectively minimize or eliminate traditional connections. Cyclic loading tests conducted study hysteretic performance and consumption proposed Considerations have been given different axial compression ratios, Belleville springs (Bes), brass plates, horizontal protocols. The test results show no obvious deformation damage during radial cyclic test. curve shape measurement approximates parallelogram, showing good force performance. increasing increase ability load-carrying capacity. Therefore, connection has perfect seismic behavior.
