SEISMIC ANALYSIS OF JIUJIAPENG BRIDGE UNDER EXCITATION OF TRAVELLING WAVE
Earthquake excitation input is an important focus in the seismic analysis. For long span bridge, the traveling wave effect should be taken into consideration. To study the traveling wave effect on long span concrete box girder, the finite element analysis is performed on Jiujiapeng Bridge. In the analysis procedure, the bridge construction process is modeled to consider the exact internal member force distribution. The box girder response under both the coincident earthquake excitation and multi-support seismic excitation is also analyzed. The analysis result shows that the bridge seismic response under multi-support seismic excitation is much different from that under consistent seismic excitation. Some useful results are drawn for the bridge aseismic assessment.
