以三水河大桥为工程背景,对超高墩桥梁地震作用下行波效应进行分析。采用SAP2000计算对比基于绝对位移法与普通加速度地震动一致激励,分析不同输入模式,不同波速对超高墩地震响应的影响。 Taking Sanshui River Bridge as the engineering background, the traveling wave effect under the seismic action of the bridge with ultra-high pier was analyzed. Comparing with SAP2000, the uniform excitation based on absolute displacement method and general acceleration earthquake are used to analyze the influence of different input modes and different wave velocity on the seismic response of ultra-high pier.
