Anchor-Bolt-Yield-Type Exposed Column-Base under Variable Axial-Force and Bending
restoring force characteristics
cyclic loading tests
An experimental study on non-slip-type exposed column bases proposed by the authors, subjected both to cyclic horizontal loadings and to variable axial forces in the limits of compression, was made to make clear bending moment characteristics of the column bases and to propose models of restoring force characteristics. In addition, the same experiments on conventional exposed column bases were conducted to show the effectiveness of the proposed column bases. The following conclusions were drawn from the experimental results: 1)The restoring force characteristics of the non-slip-type column bases become linearfrom-origin-type under variable axial forces, 2)The column bases sustain the self-centering performance reducing residual deformation of a building after an earthquake.
