【摘要】 利用结构损伤前后应变模态的变化,引入均值变点检验方法,建立了无模型条件下混凝土梁的多处损伤的损伤定位定量分析方法,并提出了定位离散模型和定位准则。数值实验表明,本方法是正确且行之有效的。更多还原

【Abstract】 The quantitative analysis of damage position of concrete beam is established. The method of damage position free of models used in this paper is based on the variations of strain mode and test of even change point. The discrete model and the position criterion are presented. Numerical example is conducted, which demonstrates that the method of damage position is correct and effective.更多还原
