Abstract:Self‐centering (SC) bridge piers generally set one or several gaps to avoid the occurrence of plastic hinges and mitigate both damage and residual drifts during major earthquakes. However, the gap opening mechanism also produces new problems in theoretical analyses, such as the strong nonlinear contact motion behavior between adjacent segments. An accurate contact mechanism is therefore significant to describe the gap‐opening process and evaluate the mechanical properties of rocking systems. Firstly, for the l… Show more
