【摘要】 钢管混凝土构件的自振特性(自振频率和振型)是结构动力特性分析和抗震设计的重要参数。文章根据结构自振特性分析理论,利用有限元模型对钢管混凝土构件的自振频率和振型进行了模拟分析,并阐述了自振频率和振型在桥梁损伤检测中的应用情况。更多还原

【Abstract】 The self-vibration(natural frequency and mode type)of the concrete filled steel tube component is an important parameter for dynamic characteristics analysis and seismic design.Based on the analytical theory of self-vibration,the article uses finite element model to perform stimulation analysis on the natural frequency and model type of the con-crete filled steel tube component,and discusses their applications in the bridge damage de-tection.更多还原
