摘要: 以平面框架为例,通过分析结构的横向柔度,深入研究了局部构件损伤对框架水平位移变化的影响机理特征。基于上述工作,利用框架的层间相对水平位移变化量(RDCSF)作为损伤特征参数,结合神经网络设计,对结构进行损伤检测分析。Abstract: On the basis of analyzing transversal flexibility of the planar frames, the influencing mechanism of the damage to local members on the displacement variation of frames is introduced.Based on the aforementioned work, the relative displacement change in storeys of the frame(RDCSF) is extracted as the damage characteristic parameter, and the structural damage detection is also analyzed by combining the design of artificial neural network.
