Analysis for Seismic Response of Long Span Rigid Frame Bridge

Xiao Jun Ning, Yi Zhou

Open full text 2 citations

Abstract

Rigid frame bridge is widely used in China because of its lower cost. The aseismatic ability of rigid frame bridge is difficult to judge for designer when the bridge is used to span valley in intensity region. The seismic response of one rigid frame bridge with 160m span is calculated. It is indicated that the aseismatic ability of rigid frame bridge is good and bridge design is controlled by bending moment at bottom of pier.
