摘要

松岙大桥主桥为260 m的钢管混凝土提篮拱桥,以该桥为研究背景分析桥梁结构的地震时程响应,应用MAT-LAB语言编写了3个程序:人造地震动、采用频域积分法将加速度时程转化为位移时程、由确定的加速度时程求其加速度反应谱,并采用SAP2000为计算平台对上述几种情况下的桥梁地震响应做了对比分析。分析结果显示,大跨度桥梁对于不同的地震波、采用不同的阻尼算法、是否考虑结构的行波效应、是否考虑结构的几何非线性其地震响应差别较大,在分析中应针对具体的桥梁结构确定合理的参数与求解方法。
Based on Songshan Bridge,whose main bridge is 260 m concrete filled steel tube handle basket arch bridge,three programs for bridges earthquake time history analysis including man-made stir-upped seismic,applying frequency domain integral method to transfer acceleration time history into displacement time history,and solving the response spectrum of acceleration by the certain acceleration time history were compiled by using MATLAB language.Comparison of the earthquake response under abovementioned three circumstances was made adopting SAP2000.The result shows that choosing different seismic waves,different damping algorithms,whether considering the traveling-wave effect,and whether considering the geometrical nonlinear of structure will all greatly effect the response of large span bridge under earthquakes.The reasonable parameters should be determined and solved according to the specific bridge structure.
