Theoretical Investigation on Multiple Separation of Bridge under Near-Fault Vertical Ground Motion

Abstract: In order to consider the effect of near-field vertical earthquake, a model of a two-span continuous beam bridge is established. On the basis of superposition of longitudinal and vertical seismic actions, the possible separation of vertical earthquake is considered, and the influence of separation on structural failure is calculated. The transient wave characteristic function method and the indirect mode superposition method are used to solve the response theory of the bridge structure during the earthquake. Wh… Show more

“…Continuous bridge is one of the common types of highway seamless structure without expansion joints. However, its construction process is more complicated and the response to imposed deformations, as temperature and foundation settlements (An et al, 2021;Chen et al, 2021), is less efficient. A link slab in steel-concrete composite bridges joins the concrete slab of two spans together but keeps the steel beams disconnected, in a so-called "semi-continuous" solution.…”
