Analysis of Rational Finite Element Model of Two-Span Skew Girder Bridge Based on Shaking Table Test

Based on the shaking table test, seismic responses of main parameters two-span skew bridge were gutted. The finite element model test was established by analysis software OpenSEES. An improved single beam quality distribution proposed. stiffness end twice that actual beam, rather than rigid arm. At same time, mass distributed in way shares half and beams at both ends share half, taking into account torsion body. Three-direction ground motion input carried out to improve response structure under three-direction obtained, comparison made between analytical results experimental results. show can consider effect while result greatly improved, which more close value, could efficiency calculation.
