| 摘 要： | 为了提高结构损伤识别的精确度和适用性,将小波分析引入到结构损伤识别中.本文介绍了梁结构在完好状态与损伤状态下振动测试加速度差的理论分析,证明了小波分析加速度差应用于桥梁结构损伤检测的可行性.然后以小波分析为工具,在桥梁结构不同损伤状态下,以移动荷载作用下各节点的加速度时程曲线差为研究对象,来识别结构的损伤状态.并通过试...

| Abstract: | In order to improve the accuracy and applicability of structural damage detection,wavelet analysis is applied to structural damage detection.The theoretical analysis of acceleration time history difference of such beam structure is detected at intact and damage states,proving the feasibility of acceleration time history difference used in bridge structural damage detection.Using the wavelet analysis,taking the acceleration time history difference of structural damage as a research object,the structural dama... |
