Abstract
A cyclic loading test was performed on a 1/3 scale model of a rectangular steel pier base-to-footing connection. From the experimental results, the maximum pier base moment and the corresponding rotational angle under cyclic loads decrease by 20% and 60%, respectively, compared with the results under monotonic loading. In the post peak range, however, the moment drop is small and the connection exhibits a stable behavior under cyclic loading. Based on the hysteretic behavior obtained by the experiment, a hysteretic model for a rectangular pier base connection was presented, following the procedure proposed by Goto et al.
