Nonlinear Dynamic Analysis of Hybrid Sliding-Rocking Bridges
This paper introduces an innovative joint element to model the hybrid sliding-rocking (HSR) joints utilized in substructure columns of HSR segmental bridges. HSR joints allow both sliding and rocking of the connected segments with respect to each other, which makes their simulation challenging. The proposed element is capable of capturing the interaction of the adjacent segments by combining a force-based (FB) beam element formulation with a hysteretic friction model and an empirical formulation for joint rocking. The empirical rocking formulation is incorporated at the element mid-length, where rocking occurs, through adaptive modification of the corresponding integration weight, which is varied throughout the analysis as the segments’ contact depth changes. The results obtained from the numerical simulations of a HSR pier using this element are in a good agreement with the past experimental data.
