The dynamic characteristics of a continuous rigid-frame bridge with fabricated super-high piers (CRFB-FSP) connected by grouting sleeves and adjacent beam bridges (AB) are significantly different, they prone to pounding under earthquake excitation. At present, the response between CRFB-FSP AB is still unclear, impact on seismic performance in exploratory stage. In this study, two 1/20 scaled mo...

Four existing methods to calculate critical separation distances between adjacent nonlinear hysteretic structures are evaluated through Monte-Carlo simulations, for which seismic excitation is characterized as a nonstationary random process. All the methods use the well-known Double Difference Combination rule, but follow different approaches to calculate the correlation coefficient ρ. Results ...
