【摘要】 对建筑结构动力特性理论进行了介绍,根据动力检测的基本原理,对钢筋混凝土屋面梁进行了检测,主要通过应变—时间曲线和FFT图谱分析研究了结构在振动荷载作用下性质的变化,从而更好地确定工程结构的实际性态。更多还原

【Abstract】 The structural dynamic characteristics theory of buildings was introduced.According to basic principle of dynamic detection,the reinforced concrete floor lintel was detected.The properties change of structures under oscillatory loading was studied mainly by strain-time curve and FFT spectrum analysis,therefore better determined practical condition of engineering structure.更多还原
