Seismic Isolation and Energy Absorption Properties Research for a Dry Joint Segment Fabricated Pier Viaduct in a Highly Seismic Region
ICTE 2015(2015)
摘要
This article proposes a bilinear stiffness plastic hinge simplified model, based on the existing experimental research on dry joints fabricated pier; Using of nonlinear time history analysis method, seismic isolation performance of combination system of dry joints fabricated pier with laminated rubber bearing is discussed in the perspective of damping isolation. Results indicate that the dry joints fabricated pier system can reduce the seismic force and energy. The conclusion has some practical significance for the applications of dry joints fabricated pier bridge in high earthquake region.
