| 摘 要： | 研究了不同的建模方式对不同的墩高、不同场地条件下桥梁地震反应的影响程度。研究发现：无论在何种场地条件、何种桥墩高度的桥梁，单梁模型在纵、横桥向地震响应的分析精度都较高，能满足工程设计需要；梁格模型纵向地震响应分析误差在5％以内，横向地震响应分析误差在10％-20％。因此，对于横向由多片梁组成的T梁桥，单梁模型建模简单且精度较高，能满足工程设计需要。

| Abstract: | The effect degree of different modeling methods to seismic response of bridge with different pier,various terrain conditions is studied.Study found:single-beam model has high analysis precision on seismic response in longitudinal direction and in transverse direction of bridge with whatever pier height and terrain condition,it completely meets needs of engineering design.The error of beam gird model is within 5% to seismic response in longitudinal direction,and the analysis error is in 10%~20% to seismic response in transverse direction.To conclude,for the multi-beam composed T-beam Bridge,single-beam model is simple and high in precision,it can meets needs of engineering design. |
