摘要:

建筑结构的损伤诊断分析是结构性能评估的基础.采用静态检测方法对梁类构件的损伤诊断问题进行了理论分析.根据梁截面等效抗弯刚度的变化建立了梁的力学模型, 利用在集中荷载作用下梁的挠度变化,并基于系统识别原理,建立了梁类构件的损伤诊断分析方法.通过实例计算,表明该方法具有较好的收敛性和稳定性.

Abstract:

The damage diagnosis and analysis of building structures is the basis for structural performance evaluation. The static detection method is used to analyze the damage diagnosis problem of beam components. According to the change of the equivalent flexural stiffness of the beam section, the mechanical model of the beam is established, and the damage diagnosis and analysis method of beam members is established based on the deflection change of the beam under concentrated load, and based on the principle of system identification. Through example calculation, it shows that the proposed method has good convergence and stability.
