摘要
利用频域中的单模态识别法(SDOFI)对珠江大桥———大跨度预应力砼连续刚构桥的现场环境振动试验数据进行桥梁动力特性识别。利用ANSYS建立了全桥三维有限元模型并进行了理论模态分析。
The single-degree-of-freedom identification(SODIF) method in frequency domain is used for the output-only data model identification. The 3D finite element model is constructed and modal analysis is performed to get natural frequencies and mode shapes by using ANSYS software.
