基于模态曲率法的木框架结构损伤识别

Damage Identification for Wood Frame Structure Based on Modal Curvature Method

通过ANSYS有限元软件得到结构位移模态分析数据,对于木框架结构在不同损伤工况下进行了模态曲率分析,研究表明模态曲率指标对于木框架的损伤比较敏感,能准确判断木框架损伤发生的具体位置,为研究木建筑结构的损伤识别奠定了理论基础。

The modal data of structural displacement is obtained by ANSYS finite element software. The different damages of wood frame structures are analyzed by the modal curvature method. The results show that the modal curvature index is more sensitive to the damage of wood frame structures and can accurately judge the detailed location of wood frame damage in order to establish the theory basis for studying the damage identification of wood building structures.
