Abstract:

Taking Sanshui 2nd Bridge as an example, horizontal seismic response of continuous rigid frame bridges with single thin piers was studied. Pile-soil interaction and structure-water interaction were considered, and seismic response affected by different water depths was analyzed. The calculated results indicate that it is detrimental to continuous rigid frame bridges when pile-soil interaction and structure-water interaction are considered. Transverse internal force of bridge piers calculated with response spectrum method is bigger; internal force of main girder and longitudinal internal force of bridge piers calculated with time-history analysis method are bigger. The analysis method combining response spectrum with time-history analysis method will be used in seismic design of continuous rigid frame bridges. The results and analysis conclusions provide a reference of seismic analysis to continuous rigid frame bridges.
