【摘要】 对同时作用有未知顶点集中荷载和未知地震荷载的框架结构的物理参数识别及荷载反演进行了研究。根据地震荷载在框架任意层上的作用都是时域相关的特点,并结合"消去法"和"统计平均法"对结构的物理参数识别的同时,反演出未知顶点集中荷载和地震荷载时程。通过具体工程算例验证该算法的有效性和可靠性;并对有噪声情况下识别进行探讨。从而为结构损伤识别提供有效的方法。更多还原

【Abstract】 The physical parameter identification and load inversion of frame structure affected by both unknown vertex concentrated load and unknown seismic load are researched.According to the temporal correlation feature of effect of seismic load on either layer of frame and combining with "Elimination Method"and "Statistical Average Method",the physical parameter of structure and inverts the time interval of unknown vertex concentrated load and unknown seismic load as well are identified.Specific engineering examples are applied to verify effectiveness and reliability of this algorithm and identification with noise is also discussed in order to provide efficient method for structural damage identification.更多还原
